the three dimensions of each roll.
Install the roller in the test rig in accordance with 6.2 and apply the mass in accordance with 4.4 and
7.3 of EN 13126-1:2006. Measure and record the initial distance in accordance with 5.2.1.
The rollers shall travel a length of 800 mm ± 10 mm. One cycle consists of one forward and one return
movement.
NOTE 1

All movements should be started without shaking and jerking.

Cycle the roller in accordance with one of the following grades at the rate of 250 +025 cycles/h.


grade 3: 10 000 cycles (+ 1 %) cycles



grade 4: 15 000 cycles (+ 1 %) cycles



grade 5: 25 000 cycles (+ 1 %) cycles

Before beginning the 90° turning procedure, sash 1 and 2 shall be arrested in the test rig into the
closed position in accordance with Figure B.2. The test specimen is adjusted by the test house in
accordance with the manufacturer’s instructions.
The sash is moved by the test rig. The initial position is located approximately 50 mm before the final
closed position. One cycle consists of an operation into the 90 ° turn position and a return operation
into the initial position.
Cycle the specimen in accordance with one of the following grades at the rate of 250 +025 cycles/h.


grade 3: 10 000 cycles (+ 1 %) cycles



grade 4: 15 000 cycles (+ 1 %) cycles



grade 5: 25 000 cycles (+ 1 %) cycles

NOTE 2

A reference velocity of 0,5 (± 0,05) m/s in accordance with EN 1191 is not required.

NOTE 3
The velocity at which the hardware is operated, results from the given rate of 250 cycles/h, taking into

account that all cycles are to be started without shaking and jerking.

Hardware shall be lubricated in accordance with 7.2 of EN 13126-1:2006.
7.2.2.4

Acceptance criteria after the 90° turning procedure

The hardware shall conform to the acceptance criteria of 8.4 of EN13126-1:2006 and the following.


Check that the hardware set functions correctly without any distortion while the load is still applied.

7.3 Additional loading test (window types Q, R and S)
7.3.1

Additional loading test in a 90 ° turn position of sash 3

Use sample A.1. Upon completion of the 90° turning procedure test the sash with the additional
loading test in a 90° turn position of sash 3.
NOTE 1
The additional loading test in a 90 ° turn position is required, if sash 3 (see Figure B.2) is an active
sash which is used as a single side-hung sash.
NOTE 2

This test is for rollers or hardware sets for window types Q, R and S and not for window type N.

Rotate the sash into the 90 ° turn-position and apply an additional vertical force of 1 000 N +50
0 N
in accordance with Figure B.3 and maintain it for 5 min +10
0 s.

During and after the additional loading test, in accordance with 5.2.3, the sash shall not drop. Hinges,
rollers and rails, lateral guides and guide tracks shall still connect the sashes to the frame.

NOTE 3

7.3.2

It is not necessary for the sash to operate during and after the additional loading test.

Additional loading test in the folded position

Use sample A.1. Upon completion of the additional loading test in accordance with 7.3.1, test the
sash in the folded position with the additional loading in accordance with Figure B.4
NOTE 1

This test is only for rollers or hardware sets for window types Q, R and S and not for window type N.

Apply an additional vertical force of 1 000 N +50
0 N in accordance with Figure B.4 and maintain it for 5
min +10
0 s.
In accordance with 5.2.3, during and after the additional loading test, the sash shall not drop. Hinges,
rollers and rails, lateral guides and guide tracks shall still connect the sashes to the frame.
NOTE 2

It is not necessary for the sash to operate during and after the additional loading test.

7.4 Static endurance test at ambient temperature
7.4.1

Rollers for horizontal sliding windows and doors (window type N)

Use sample A.2 for the static endurance test at ambient temperature (3.6 of EN 13126-1:2006) in
accordance with Figure A.2.
Inspect the rolls for surface imperfections. Measure and record the initial diameter of each roll at the
contact point of the roll and the corresponding rail. Mark the contact point on each roll.
Install the roller in the test rig in accordance with Figure A.2 and apply the mass in accordance with
4.4 and 7.3 of EN 13126-1:2006 for 240 +240 h.
The roller shall conform to the acceptance criteria of 8.4 of EN13126-1:2006 and the following.


Check that the roller functions correctly without any distortion while the load is still applied.



Remove the load from the roller. Immediately after removing the load measure and record the
final diameter of each roll at the pre-marked contact point. The difference between any initial and
final dimension shall not deviate by more than 5 % in accordance with 5.2.4.1.

7.4.2 Rollers for sliding folding windows and doors (window types Q, R and S)
Use sample A.2 for the static endurance test at ambient temperature in accordance with Figure B.5.
Inspect the rolls for surface imperfections. Measure and record the initial diameter of each roll at the
contact point of the roll and the corresponding rail. Mark the contact point on each roll.
Install the roller in the test rig in accordance with Figure B.5 and apply the mass in accordance with

4.4 and 7.3 of EN 13126-1:2006 for 240 +240 h.
The hardware shall conform to the acceptance criteria of 8.4 of EN 13126-1:2006 and the following:


14

Remove the load from the roller. Immediately after removing the load, measure and record the
final diameter of each roll at the remarked contact point. The difference between any initial and
final dimension shall not deviate by more than 0,5 % in accordance with 5.2.4.2.


BS EN 13126-15:2008
EN 13126-15:2008 (E)

NOTE
An alternative test rig may be used, that provides the same loads resulting from the test rig (see
Figure B.5).

7.5 Corrosion resistance
NOTE 1

This test is necessary if the manufacturer cannot provide a test report in accordance with EN 1670.

All corrosion tests shall be on original new samples. For Zinc galvanized surfaces on iron or steel the
specified thickness of 12 µ (class 3) or 16 µ (class 4) is not necessary if other surface protection
methods are used to conform to the requirements (Minimum time to formation of white corrosion
products) of ISO 4520 (µ = micrometre).
Unless a test report can be provided by the manufacturer, the hardware shall be tested in accordance
with EN 1670.
NOTE 2 The evaluation of the corrosion resistance is limited to the essential areas (as a rule, the visible

surfaces of the installed hardware).
Exempt from the corrosion resistance evaluation are:
- rivet locations;
- locations of later processing (for example: cleaved surfaces that result from cropping the hardware
components, millings etc.);
- non surface-treated parts/surfaces, provided they are not in the visible vicinity of the hardware (for
example: screw guide-holes made of zinc die-cast etc.);
- welding joints and their immediate surroundings.
