1 - a gear wheel combined with a closer spindle; 2 - piston with a toothed rack; 3 - closer body (hydraulic cylinder); 4 - returnable spring

Figure B.1 - Example of a closer design

The closer consists of a body 3 (hydraulic cylinder), divided into two cavities with a working fluid by a piston 2, made as a whole with a toothed rack. To ensure the tightness and performance of the door closers at various temperatures (temperature range from minus 35 ° C to plus 40 ° C), it is recommended to use ESSO Univis HV126 oil (made in the USA) as a working fluid. The characteristics of the oil are shown in Table B.1.

Pour point, ° С
Flash point, ° С

Gear 1 aligned with the closer spindle, rigidly connected to the link arm (not shown in the figure). When the door is opened, torque is transmitted through the link arm, causing the spindle and gear to rotate 1 ... Rotating, the gear moves the rack, which causes the piston to move forward. 2 ... Piston Compressing Spring 4 and displacing oil, moves to the right side. Oil flows through the bypass valve located at the end of the piston into the left cylinder cavity.

The valve must have a sufficient cross-section so as not to resist when opening the door. After the door is released, the piston, under the action of the spring pre-compressed when opening, starts the reverse movement. The bypass valve closes and the oil flows through special channels with adjusting screws. By turning the adjusting screws, the channel cross-sections are increased or decreased, changing the oil consumption and, accordingly, changing the door closing speed. The door will close faster if the channel cross-section is increased, slower if the channel cross-section is reduced.

Figure E.4 - A device for testing overload closers

E.1.5 The stand should be provided with means by which the test door, opened at 90 °, can be suddenly released, as well as means for fixing falling weights, so that when the test door reaches an angle of 15 ° from the closed position, the load or traction cable does not interfere. further closing the test door.

The opening and closing forces are measured with a dynamometer with an accuracy of at least class 2 in accordance with GOST 9500 or another similar device. The actuators used in the reliability tests shall not prevent the test door from returning to the fully closed position.

E.1.6 Installation and fastening of the closer on the test door should be carried out in a position corresponding to the operating conditions.

E.2 Sampling

E.2.1 Three samples are taken to test the door closers:

- sample A for testing the closers for reliability and resistance to mechanical stress;

- sample B to determine the dependence of the main characteristics of the closers on temperature (if necessary);

- sample B for testing for corrosion resistance (for door closers with the function of adjusting the closing force, sample B must be set to the minimum closing force).

E.2.2 If the tested door closer has the function of adjusting the closing force, then to test the reliability and determine the dependence of the main characteristics of the closers on temperature, use two closers, one of which is set to the minimum and the other to the maximum closing force declared by the manufacturer.

E.3 Testing

E.3.1 Test for reliability and mechanical strength (sample A)

E.3.1.1 Before the test, the closers are adjusted:

a) for complete closing of the door from an angle of 90 ° for a time from 3 to 7 s;

b) for a smooth transition from the closing speed to the closing speed and for non-clapping door closing for door closers with the final closing function;

c) set or disable the opening damping function for the minimum action;

d) turn off the door closer opening locking device or test a similar model of door closers without opening locking device.

E.3.1.2 The safety test cycle for door closers for unilateral opening doors should include opening the door at an angle of 90 ° in a time of 2-3 s and returning it to the closed position using the door closer.

E.3.1.3 The test cycle for the reliability of closers for swing doors should include the alternation of operations to open the door at an angle of 90 ° and completely close it with the closer in both directions.

E.3.1.4 The test to determine the moments of opening and closing is carried out after 5000 operating cycles and after the end of the reliability test.

E.3.1.4.1 Closing time regulators are adjusted to the full opening position. The opening and closing forces of the door closers are measured with a dynamometer located perpendicular to the surface of the test door leaf at the place where the handle is installed, by slowly (not faster than 1 ° / s) opening and closing the test door.

E.3.1.4.2 Measure the maximum door closing force with a dynamometer when the door is in the open position at an angle from 0 ° to 4 ° and from 88 ° to 90 °. The average value of the parameter being determined is calculated from the results of three measurements.

E.3.1.4.3 Measure with a dynamometer the maximum force of opening the door at an angle from 0 ° to 60 °. The average value of the parameter being determined is calculated from the results of three measurements.

E.3.1.4.4 Measure with a dynamometer the minimum force of complete closing of the door from the largest opening angle declared by the manufacturer. The average value of the parameter being determined is calculated from the results of three measurements.

E.3.1.4.5 Moments of closing and opening of the closer, Nm, calculated by the formula

where is the force of closing or opening of the closer, measured by a dynamometer, N;

- door width minus 70 mm (handle installation place), m.

The closing and opening moments in each range of door opening angles must correspond to the values given in table 1 for the tested door closer of each class.

E.3.1.4.6 The efficiency of the closer is determined as a percentage as the ratio of the average value of the maximum closing force at an angle from 0 ° to 4 ° to the average value of the maximum opening force at an angle from 0 ° to 4 °.

The closer efficiency shall correspond to the values given in Table 1 for the tested closer of each class.

E.3.1.5 The door closing time is determined before the start of the test, after 5000 operating cycles and after the end of the reliability test.

After 5000 operating cycles according to 5.4.1, the possibility of adjusting the closing time of the tested closer from an angle of 90 ° is determined.

E.3.1.6 Testing of closers with overload when closing is carried out after 5000 operating cycles and after the end of the reliability tests

E.3.1.6.1 The test of door closers by overloading the door when closing is carried out on a stand (see Figure E.1), provided with falling weights, a cable, means for fixing falling weights, when the door reaches an angle of 15 ° from the closed position and the door is fixed in the closed position.

A device for testing door closers by overload is shown in Figure E.4.

E.3.1.6.2 Set the time for closing the door from an angle of 90 °, equal to 10 s.

E.3.1.6.3 The test cycle involves holding the test door open 90 ° with the counterweight weights and then releasing it with the weights falling. The number of test cycles is 10.

E.3.1.6.4 Measure with a dynamometer the maximum frictional force of the test door when it is closed from an angle of 90 ° under the action of weights and calculate its average value.

The maximum frictional force of the door when closing should correspond to the class of the tested door closer according to table 3.

E.3.1.7 Test of door closers with a closing delay function

E.3.1.7.1 The closer is adjusted for the maximum closing delay time.

E.3.1.7.2 When the door is closed from the 90 ° position, measure with a dynamometer the force required to manually pull the test door out of the delay zone (opening area at least 65 °) in a time of 2-5 s.

The average value of the parameter being determined is calculated from the results of three measurements.

The torque required to manually override the delay should not exceed 150 Nm.

E.3.1.7.3 Using the adjustment controls, it is necessary to make sure that at a temperature of 20 ° C the closer has the ability to adjust the time of closing the test door from the 90 ° position to the end of the delay zone for at least 20 s.

E.3.1.8 After the reliability test, re-check the closing time, closing moment, efficiency, maximum closing time and overload tests when closing.

E.3.1.9 A flowchart of the closer test procedure is given in Appendix D.

E.3.2 Tests at extreme temperatures (sample B)

E.3.2.1 When determining the closing time under extreme temperatures (see 5.1.4), an assessment is made of the change in the time that the door closer fully closes from an angle of 90 °.

E.3.2.2 Before each test, the door closer must be kept in extreme temperatures for at least 8 hours. The average value of the time the door closes with the door closer at each given temperature is calculated from the results of three measurements carried out without rebuilding the regulators.

E.3.2.3 The test is carried out in the following sequence:

- set the temperature of the closer (20 ± 1) ° С and regulate it to smoothly close the door from an angle of 90 ° within 5 s. Calculate the average closing time;

- set the temperature of the closer to minus (15 ± 1) ° С (and below) and, slowly opening the test door by 90 ° in a time of at least 4 s, measure the time of complete closing of the door. Calculate the average closing time;

- without reconfiguring the closer regulators, set the temperature of the closer (40 ± 1) ° С and measure the time of complete closing of the door from an angle of 90 °. The average closing time is calculated.

The average door closing time from a 90 ° angle under extreme temperature conditions shall not fall below 3 s and shall not exceed 25 s (see 5.1.3).

E.3.3 Corrosion resistance tests (sample B)

Before tests for corrosion resistance, the closing moments are calculated according to D.3.1.4.5, and after the corrosion resistance tests, no later than 24 hours later, the closing moment is calculated again according to D.3.1.4.5. After testing for corrosion resistance, the closing torque of the door closer shall be at least 80% of the torque calculated before the corrosion resistance tests.

Currently in Russia in relation to door closers there are state standards former USSR, adopted (or republished) in 1987. The definition of an overhead door closer is given in GOST 27346-87 “Locks and hardware. Terms and Definitions". The requirements for door closers are fully defined in GOST 5091-78 "Hardware auxiliary for wooden windows and doors. Types". The only essential requirement for door closers, in accordance with the current standards, is the number of cycles of failure-free operation. But even this requirement is not consistent with the current regulatory framework for doors of various types and various fields of application.

Due to the backwardness of the current regulatory framework, experts in the field of door technology use European standard EN1154 Controlled door closing devices. In April of this year, European Directive No. 2: 2011 Controlled Door Closing Devices and Systems was issued, which sets out basic guidelines for the selection, installation and maintenance of door closers and equipment for fire doors and doors installed on escape routes. This directive was developed by ARGE, a European union of locks and building hardware associations, which brings together national associations in 16 European countries. These two documents will form the basis of a new CIS interstate standard for door closers and auxiliary systems, which will be developed in the near future.
In connection with the above, in this article we will rely on the concepts and requirements that are defined in the current European regulatory documents.

Types of door closers

The role of door closers in construction is extremely important - the door closer guarantees the correct closing of the door in the event of a fire, as well as when external climatic conditions deteriorate, serves to maintain the functionality of ventilation and air conditioning, etc. But at the same time, the door closer must ensure the comfort of operation of the door itself, so that users, especially children and the elderly, can open the door without any problems. It is these two functions that should be taken into account when choosing door closers - comfortable door opening and guaranteed door closing.
So what is a door closer in terms of European regulations?
Door closer is a generic term for various types of hydraulic controlled mechanisms designed for controlled closing of stop doors and swing doors, which can be installed on / in the door structure, integrated into the floor or into the upper part of the opening. The main purpose of the door closer is to ensure self-closing of the door, that is, the open door must return to the closed position without human intervention, and the closing process must be hydraulically controlled.
Currently there are different options installation of door closer depending on the type of door closer, type of door and the internal structure of the door.

1. Overhead door closer with guide rail
With regard to mounting options, slide rail door closers are universal - they can be installed both on the frame and on the door leaf, as well as on the hinge side and on the opposite side of the hinge. The installation option is selected depending on the geometry and design of the door leaf and frame, as well as the direction of door opening, while taking into account the visual appeal of the entire system. However, when choosing the installation option, it is necessary to check the permissible opening angle of the door, since some restrictions are possible.

2. Overhead door closers with link arm
The most common type of door closers. However, there are a number of limitations regarding mounting options. In the standard version, only sash mounting from the hinge side and frame mounting from the opposite hinge side are possible. When choosing an installation option, it is necessary to take into account the fact that the door closer cannot be installed with outside front door where it will be exposed to the environment.

3. Concealed overhead door closers
As a rule, hidden door closers are installed in the door leaf. However, installation in a frame is also possible. Concealed door closers are usually used when presented high requirements to the door design. In addition, the hidden installation option provides this type of door closers with a high level of anti-vandal protection, as well as increased corrosion resistance. Leading manufacturers have in their lineup Concealed closers for both stop and swing doors. Concealed overhead door closers have a number of restrictions on the opening angle, as well as on the thickness of the door leaf.

Door closer is a generic term for various types of hydraulic controlled mechanisms designed for controlled closing of stop doors and swing doors, which can be installed on / in the door structure, built into the floor or in the upper part of the opening

4. Floor closers
Floor springs (floor-mounted closers) can be used for both swing doors and stop doors. This type of door closers is exclusively recommended for very heavy doors up to 300 kg. Floor springs are widely used in combination with glass clamping fittings for all-glass doors. And also floor closers, along with closers built into the upper part of the opening, are in many cases the only solution for swing doors.

Table 1. Classification of door closers by closing force

Closer strength	Recommended max. width sash (mm)	Recommended weight sash (kg)
1		20
2	850	40
3	950	60
4	1100	80
5	1250	100
6	1400	120
7	1600	160

5. Closers built into the upper part of the opening
By and large, closers of this type are similar in functionality to floor closers. The main difference is that door closers built into the upper part of the opening do not require additional floor preparation.

The main characteristics and functions of the comfort closers

The main characteristic of a closer is the closing force of the closer (sometimes the terms "closer size", "closer force" or "closer force" are used). Table 1 shows the door closers classification according to the closing force in accordance with EN1154.
As we said above, the door closing process must be hydraulically controlled. Therefore, below we will briefly review the basic comfort functions of the door closers (the hydraulic functions of the door closers).
1. Closing speed - adjustable speed with which the closer closes the door from the open position.
2. Final latch - adjustable speed with which the door closer closes the door at the last stage of door movement (15 ° –0 °) to the closed position.
3. Opening damping - safe slowdown (increase in resistance) of door opening to prevent uncontrolled opening of the door.
4. Deceleration of closing - deceleration (braking) of door closing in a certain area, for example, in the range of 90 ° –65 ° (in accordance with the recommendations of EN1154).

The choice of closers

The type of door closer is selected after analyzing all conditions affecting the functioning and comfort of the door operation, based on the type and internal structure of the door. The correct choice of a closer with a specific set of comfort functions and additional options is influenced by many factors. Below we will consider the main ones and define the basic rules for the correct choice of door closers.
1 area of use
a) Fire doors
Must be paid great attention and take extra care when choosing closers for fire doors and doors installed on escape routes.
A fire door is a structural element that serves to fill openings in fire barriers and prevents the spread of fire into adjoining premises for a specified time. The fire door is an essential element fire protection building. In accordance with the technical regulations on fire safety requirements (Federal Law No. 123-FZ dated July 22, 2008), fire doors must have self-closing devices. In this case, fire doors that can be operated in the open position must be equipped with devices that ensure their automatic closing in the event of a fire.
Evacuation exits are exits leading to an escape route, directly outside or into a safe area. In accordance with SP 1.13130.2009 “Fire protection systems. Evacuation routes and exits ”, staircase doors, as well as doors of emergency exits from premises with compulsory smoke protection, including from corridors, must be equipped with self-closing devices.
The type of fire door closer is determined in the technical documentation for the door. The fact is that when testing a door for fire resistance, in accordance with GOST R 53307-2009 “Building structures. Fire doors and gates. Fire resistance test method ", during the tests the samples must be completed and assembled in full compliance with the technical documentation.
As a rule, overhead door closers with a link arm are installed on fire doors, less often with a sliding rail. But this is not a dogma. Some companies that produce fire doors special purpose or high-quality stainless steel doors, completing their products with hidden overhead door closers.
Closers installed on fire doors cannot be equipped with mechanical fixing devices - the elements for fixing the door in the open position must be connected to the building's fire protection system and must ensure that the door is closed in the event of a fire. During normal use, external electromagnetic devices, electromechanically latching rail door closers or electro-hydraulically latching link / rail door closers can be used to hold the door open during normal use. In practice, electromagnetic devices are widely used, as well as slide rail door closers with electromechanical fixation.
It should also be noted that double-leaf doors with an emphasis must be equipped with devices for coordinating the closing of the door. The closing sequence function for double-leaf doors ensures the correct closing sequence - first the passive leaf closes and then the active leaf. This function is realized in the following way: the active leaf is held in the open standby position until the passive leaf is completely closed, after which it closes.
Devices for coordinating door closing are divided into 4 main groups:
- integrated into door closers;
- integrated into door closers with electric hold-open;
- hidden door coordinators;
- external door coordinators.
In practice, external door closing coordinators are commonly used in combination with link arm overhead door closers. But in Lately more and more began to be used modern systems according to European standards - systems consisting of two overhead door closers with a guide rail with integrated closing sequence coordination.
b) Entrance doors
In accordance with GOST 24698-81 from 01.01.1984, “Wooden external doors for residential and public buildings. Types, design and dimensions ", entrance and vestibule doors must be equipped with door closures to protect against mechanical damage, reduce noise and heat loss. When choosing closers for an entrance door, there are 2 main factors to consider. Firstly, the door closer should only be installed on the inside of the door and, as a rule, it is installed on the frame. Secondly, the closer must have an opening damping function.
c) Doors for special groups of the population
Special (low-mobility) groups of the population include people with disabilities, people with temporary health problems, pregnant women, elderly people, children, people with strollers, etc. To create a full-fledged architectural environment that ensures the required level of accessibility of buildings and structures for all groups of the population and their unhindered use, in accordance with SP 35-101-2001 “Design of buildings and structures, taking into account accessibility for people with limited mobility. General Provisions ", there are additional requirements for the maximum force when opening the door - no more than 25 N. Also, the door width must be at least 900 mm. Only modern door closers from leading European manufacturers with high efficiency meet such stringent requirements.
In some cases, for example, for the unimpeded passage of a person in a wheelchair, the door closer must have the function of slowing down the closing within a specified range for a specified period of time (0-30 sec).

Due to the backwardness of the current regulatory framework, experts in the field of door technology use the European standard EN1154 Controlled door closing devices. In April of this year, European Directive No.2: 2011 Controlled Door Closing Devices and Systems was issued, which sets out the basic guidelines for the selection, installation and maintenance of door closers and equipment for fire doors and doors installed on escape routes. This directive was developed by the European Union of Lock and Hardware Associations ARGE, which brings together national associations in 16 European countries. These 2 documents will form the basis of a new CIS interstate standard for door closers and auxiliary systems, which will be developed in the near future.

2. Width and weight of the door
After selecting the required type of door closer with a given set of comfort functions for specific operating conditions and installation option, it is necessary to determine and correctly set the force of the closer for a given door width in accordance with Table 1 above in this article. It should be noted the following important factors affecting the choice of a closer, depending on the width and weight of the door. The sash widths shown in the table are based on standard conditions. In the case of high or heavy sash, with a high wind load, with large differential pressures of the indoor and outdoor air, as well as other additional limiting conditions, a closer with a higher force must be used.
The recommended door weight does not limit the maximum allowable door weight for a particular door closer force - the recommended sash weight is used for testing. The maximum permissible sash weight is determined in the manufacturer's documentation. For example, there are door closers with EN7 force for sash widths up to 2000 mm and weight up to 350 kg.

b) closing the door

1 - gear, combined with the closer spindle; 2 - piston with a toothed rack;

3 - closer body (hydraulic cylinder); 4 - returnable spring

Figure B.1 - Example of a closer design

Gear 1 is aligned with the closer spindle, rigidly connected to the link arm (not shown in the figure). When the door is opened, a torque is transmitted through the link arm, which causes the spindle and gear 1 to rotate. When rotating, the gear moves the toothed rack, which leads to the translational movement of the piston 2. The piston, compressing the spring 4 and displacing the oil, moves to the right side. Oil flows through the bypass valve located at the end of the piston into the left cylinder cavity.

The valve must have a sufficient cross-section so as not to resist when opening the door. After the door is released, the piston, under the action of the spring pre-compressed when opening, starts the reverse movement. The bypass valve closes and the oil flows through special channels with adjusting screws. By turning the adjusting screws, the channel cross-sections are increased or decreased, changing the oil consumption and, accordingly, changing the door closing speed. The door will close faster if the channel cross-section is increased, slower if the channel cross-section is reduced.
