Speciality Doors & Frames/Commercial & Special Use Doors

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.

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.

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.

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.

Materials and design requirements for food equipment: surfaces that must be cleanable in a commercial kitchen or food plant.

Made from materials accepted for contact with food, which is what allows the product into a food preparation or cold storage area.

Classification of rigid PVC compounds by their mechanical and thermal properties: what a PVC component's cell classification refers to.

Surface burning characteristics: the flame spread index and smoke developed index a material is classified by. Class A is the usual requirement in an occupied building.
