All components are required to adhere to product certification requirements that are acceptable to the local Authority Having Jurisdiction (AHJ) by meeting the requirements of the local building code and fire code. The regulatory requirement will change from country to country.
For example in the United Kingdom a fire resisting doorset should be sujected to either a British Standard Fire Test BS 476 Part 22 1987, or a BS/EN 1634-1 2000 test. The results are recorded by the test house or Institute and given in a report which will also detail such things as constructional details, distortion data and pressure readings. These tests are applicable to the performance of the specimen tested. It is the Building Regulations approved Document B or British Standards such as the BS 5588 series which lays down the criteria for the fire performance such as 30 minutes FD30 or FD30(S) if cold smoke resistance is required.
Similar technical guidance documents and building regulations are in effect in other countries.
Combustibility
Fire doors are not necessarily all noncombustible. A fire door is but one of many passive fire protection components used to compartmentalise fire and thus keep it in the compartment of origin, so either it runs out of fuel or it is extinguished, or, at the very least, enough time has been bought to enable evacuation of the building.
Fire Door 防火門, 防火玻璃門 產品認證 (PCCS-FD) - recognized by the HKCSL (Hong Kong Certification Services Limited) to ensure the door quality as well as performance reliability.
