EN 13126-6-2017 pdf download.Building hardware – Hardware for windows and door height windows – Requirements and test methods – Part 6: Variable geometry stay hinges (with or without a friction stay).
513 Corrosion resistance
Hardware shall conform to the grades listed in EN 1670.
Unless already stated with a test report by the manufacturer, relevant components which are representative for the hardware shall be tested in accordance with EN 1670. As specified in EN 1670 the hardware components shall not be mounted on a window profile for the corrosion test.
6 Test equipment and preparation for the test
6.1 Test-rig
The test-rig shall be so rigid that any deformation during the tests shall have no influence on the results.
The test shall be conducted on a test-rig which corresponds in function and shape to the sash for which the hardware is intended. The dimensions of the test-rig shall conform to 4.5.
6.2 Specimen
The variable/parallel geometry stay hinge (with or without a friction system) shall be installed in the specimen for testing in accordance with the manufacturer’s fixing instructions. The hardware tested shall conform to the manufacturer’s recommendations for size and mass of the specimen. The tolerance for the specimen (test sizes) is ± 2 mm.
The specimen shall be infilled with an adequately rigid timber-based panel, PVC, steel or timbercomposite material; this substitutes the glazing.
The specimen shall be installed in a supporting sub-frame using common-practice building procedures.
A circumferential clearance of 5-10 mm between the frame member and the sub-frame shall be allowed;
the area at the fasteners should be compression resistant packed. As a rule, fixings should be spaced
150 mm from the corners; additional fixings shall be with a distance of 400 to 600 mm.
The specimen shall be provided with adjustable datum surfaces near the free corners of the edge of the casements, opposite to its detected locking rail, so that wear and loss of pull-in can he detected.
Any gap between sash and outer frame shall be equal to the working stack height of the variable /
parallel geometry stay hinge (with or without a friction system) mm.
lithe fixing position of the variable/parallel geometry stay hinge (with or without a friction system) is not specified, the variable/parallel geometry stay hinge (with or without a friction system) shall be mounted with its centre line in the plane containing the centre of gravity of the sash, or test panel, to ± 3 mm and as close to its free corners as practicable.
The general tolerance in this standard is +5 % unless otherwise specified.
The hardware manufacturer shall provide test specimens for the testing institute. A drawing of the profile cross-section with relevant information shall be enclosed in the test application, which also contains the necessary hardware installation information for the windows.
Purpose-built steel test apparatus may also be used. Mounting blocks should be used to ensure the fixing gap on the test apparatus is equal to the working stack height of the variable/parallel geometry stay hinge (with or without a friction system).
6.3 Mounting of specimen
The supporting sub-frame with the specimen to which the samples are fastened during the test, shall be fixed to the test rig. The mounting of the supporting sub-frame on the test rig shall represent a typical application and not impair its performance during the durability test.
Instructions for the application of additional stays and other devices in the specimen shall be observed. 6.4 Additional equipment
6.4.1 Block for pull-in abuse test
The pull-in abuse test requires a softwood block of dimensions (25 x 25 x 6) mm ± 10 % (see Figure B.3).
6.4.2 Steel cross for simulated negative pressure test
The simulated negative pressure test requires a welded steel cross to be used to distribute the applied force to the mid-points of the panel rails and stiles.
7 Test procedures
7.1 Samples
Four (hardware) sample sets shall be used [or testing in accordance with this European Standard:
sample A – pull-in, friction and pull-in abuse tests;
sample B — pull-in, durability, simulated negative pressure tests and parallelism test;
sample C – corrosion tests (representative hardware components;
sample D — retained for reference control.
Sample C should only be necessary If no test report can be supplied from the manufacturer regarding the testing of the hardware components in accordance with EN 1670.EN 13126-6-2017 pdf download.
