Table 4 - Acceptance inspection and periodic testing

Apecs has updated the range of door closers in the 2.0 series. This is due to changes in certification. The use of the new standard makes it possible to more accurately determine the class of a door closer. Thus, each buyer will be able to choose a door closer that suits his door.

Until this point, the nomenclature used the traditional method for the Russian market to indicate the force of the closer - each model corresponded to a certain weight range of the door leaf. It is these ranges that were reflected in the nomenclature of the door closer, for example, in the 2.0 series: DC-2x/25-45, /40-65, /60-80, 80-100, 100-120.

This tradition has clear historical roots. Because we're talking about about door closers are of Chinese origin, and Chinese manufacturers are mainly focused on the US market. In the USA, to determine the requirements for door closers, the American standard ANSI/BHMA A156.4 was used, which is based specifically on the weight of the door.

ANSI – American National Standards Institute

BHMA – Builders Hardware Manufacturers Association

The Chinese standard for door closers is based precisely on it. Consequently, factories producing door closers in China mainly use door weight to describe their models. Russian companies also followed this principle.

However, this approach is not entirely correct. Obviously, the force that the closer needs to close the door depends not only on the weight of the door, but also on the location of the closer installation on the door (the farther from the line of hinges, the easier it is to close the door), and the distribution of the weight of the door in the doorway (the wider canvas, the more difficult it is to close the door).

European manufacturers of door closers are guided by a different principle of product classification. The priority parameter for dividing door closers into classes here is the width of the door leaf, and weight is of secondary importance. This principle is described by the standard - EN 1154.

On January 1, 2015, it was adopted and put into effect in Russia new standard"GOST R 56177-2014. Door closing devices (closers)."

3. Approved and put into effect by Order of the Federal Agency for Technical Regulation and Metrology dated October 21, 2014 N 1357-st.

4. This standard complies with the European regional standard EN 1154:1996 "Building hardware - Controlled door closing devices - Requirements and test methods", NEQ) in terms of technical requirements and test methods.

5. Introduced for the first time.

The new Russian standard fully complies with the European standard EN 1154, which European companies are guided by, including those supplying door closers to the Russian market.

In accordance with the new GOST, door leaf width has been added to the range of Apecs closers. This also allows you to separate closers with different forces that are within the same EN (GOST Class).

Now in the nomenclature of Apecs closers we can read:

· Presence (or absence) of built-in fixation;

· Lever type included;

· Door closer color.

The advantage of this approach was greater variability and accuracy when selecting a door closer. If we were guided by only one parameter - the weight of the door, then we often had to buy a door closer of obviously greater power than would be required when taking into account the width of the door leaf. If there is a need to install a door closer on a door that has been in use for a long time (for example, the entrance door of a residential building), then determining its width using a tape measure is much easier than the weight, since for this the door would have to be removed. Thus, the use of the GOST R 56177-2014 standard greatly facilitates the acquisition of such an important part for long-term and high-quality operation of the door as a door closer.

The maximum parameters are determined by the design of the closer and are recommended by the manufacturer along with the installation diagram on the door leaf.

Requirements for closers intended for use in fire/smoke door structures

B.1 The scope of application of closers is the design of fire/smoke doors with a given fire resistance limit based on the results of fire tests of the door structure equipped with this closer.

Closers can be used on doors that are similar in design to the one being tested and used under the same operating conditions.

B.2 In the designs of fire/smoke doors, closers with a closing force of at least class 3 according to Table 1 must be used.

B.3 A locking device in a separate position is not allowed in closers unless it is an electrical locking device.

B.4 The delay function for closing the closer must be configured to close the door from an angle of 120° to the boundary of the delay zone in a time of at least 25 s.

B.5 To eliminate the possibility of blocking the closing or other action of the closer, the closer control regulators must be hidden or activated using a special tool.

Appendix B (for reference)

An example of a door closer design and its operation diagram

a) opening the door

b) closing the door

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

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

Figure B.1 - Example of a closer design

The closer consists of a housing 3 (hydraulic cylinder), divided into two cavities with working fluid by a piston 2, made as a single unit with a gear rack. To ensure tightness and operability of closers at different 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 oil characteristics are given in Table B.1.

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

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