Introduction of GB 12955-2008

1 Scope This national standard specifies the classification, code name, tag, requirement, test method, test rules, sign, packing, transportation and storage of the fire resistant door sets. This standard is applicable to timber, steel and timber-steel fire resistant hung door sets and other material fire resistant door sets. As for other open mode fire resistant door sets, refer to this standard. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this standard. For date reference, the subsequent amendments to (excluding amending error in the text) or revisions of, any of these publications do not apply. And parties to agreements based on this standard are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. For undated references, its latest edition referred to applies.

Hinge is the shaft perpendicular to the floor, this shaft can rotate clockwise or counterclockwise to open or shut the fire resistant door sets of the door wing. 3.2 Fire resistant timber door sets Use the flame resisting timber, flame resisting timberwork to make the doorframe, door wing frame, door wing panel and filling material within the door wing, then fill the fireproofing heat insulating material that is harmless for the human, then form the door with the fire resisting property by assembling with the hardware fittings. 3.3 Fire resistant steel door sets Use the steel material to make the doorframe, door wing frame, door wing panel and fill material within the door wing, then fill the fireproofing heat insulating material that is harmless for the human, then form the door with the fire resisting property by assembling with the hardware fittings. 3.4 Fire resistant timber door sets with steel structure Use the steel material, flame resisting woodiness material or flame resisting timberwork to fabricate the doorframe, door wing frame, door wing panel and filling material within the door wing, then fill the fireproofing heat insulating material that is harmless for the human, then form the door with the fire resisting property by assembling with the hardware fittings. 3.5 Other material fire resistant door sets Use the inorganic noncombustible material, steel, flame resisting timber and flame resisting timberwork but not the steel material, flame resisting wood or flame resisting timberwork to fabricate the doorframe, door wing frame, door wing panel and filling material, then fill the fireproofing heat insulating material that is harmless for the human, then form the door with fire resisting property by assembling the hardware fittings. 3.6 Fully insulated door sets Within the time specified, this door set can meet the requirements for fireproof integrality and ablative insulating quality. 3.7 Partially insulated door sets Within 0.50 h greater than or equal to the requirement, fireproof integrality and ablative insulating quality requirement can be met; when 0.50 h is exceeded, fireproof integrality requirement of the fire resistant door sets can also be met. 3.8 No insulated door sets Within the time specified, the door set can meet the requirements for fireproof integrality and ablative insulating quality.
