The designations below are cited by the products on this page. A specification is written in these, not in product names, so each one is set out with what it governs. Progress Horizon Trading supplies this line as an authorized distributor across Saudi Arabia.
SASO standards
The Saudi Standards, Metrology and Quality Organization requirements: what a product must meet to be placed on the Saudi market.
BS 476-22
The older British fire resistance test for non-loadbearing elements, tested at roughly neutral furnace pressure. Still cited on UK-legacy specifications alongside EN 1634-1.
EN 1634-1
The European fire resistance test for door and shutter assemblies, and the basis for CE marking a fire door. Built on a different pressure regime from UL 10C, so the two ratings are not interchangeable.
UL 10C
The positive pressure fire test for door assemblies. Positive pressure drives hot gas through any gap between door and frame, which makes it the more demanding test and the one North American codes now call for.
NFPA 80
Not a test but a compliance standard: how fire doors are installed, inspected and maintained, including the annual inspection and the requirement that every fire door self-closes and positively latches.
ANSI/WDMA I.S.1A
The American standard for architectural wood flush doors, covering construction, performance duty level and warranty.
