Fire tests — Full-scale room test for surface products
Specifies a test method that simulates a fire that under well ventilated conditions starts in a corner of a small room with a single open doorway. The method is intended to evaluate the contribution to fire growth provided by a surface product using a specified ignition source. It is especially suitable for products that for some reason cannot be tested in a small laboratory scale, e.g.…
Truck and bus tyres — Verifying tyre capabilities — Laboratory test methods
Of the test methods presented (strength test for the structure, endurance test), only some may be required depending on the type of tyre to be tested. The tests are carried out in a laboratory under controlled conditions. Applies to all truck and bus tyres.
1 Scope
O437.0
1.1 This Standard pertains specifically to a class of mat-formed structural panelboards made predominantly of wood strands or wafers of a minimum and controlled length, a controlled thickness, and a variable or predetermined width, bonded together with a waterproof and boilproof binder.
1.2 These panelboards are intended, and used extensively, for construction applications…
