A fire door is a door that can meet the requirements of fire resistance stability, integrity, and thermal insulation within a certain period of time. It is a fire separation component with a certain level of fire resistance, installed in fire compartments, evacuation stairwells, vertical shafts, etc.

Classification by material: wooden fire doors, steel fire doors, steel-wood fire doors, and other fire doors. Fire doors are an important component of firefighting equipment and a crucial part of social fire prevention. Therefore, many large domestic fire door manufacturers need to obtain corresponding fire certification (GB 12955-2015).

GB 12955-2015 is the national standard for fire doors, replacing GB12955-1991 "General Technical Conditions for Steel Fire Doors" and GB14101-1993 "General Technical Conditions for Wooden Fire Doors".

The main changes in this standard compared to GB 12955-1991 and GB 14101-1993 are as follows:

—— The classification of fire door fire resistance performance has been revised, changing from the previous Class A, B, and C classification to "Insulated Fire Doors (Class A)", "Partially Insulated Fire Doors (Class B)", and "Non-Insulated Fire Doors (Class C)" (GB12955-1991, GB14101-1993):

The requirements for materials used in fire doors are more comprehensive and specific, adding requirements for combustion performance and smoke toxicity of materials other than metal materials (GB12955-1991 and GB14101-1993):

GB 12955-2015 primarily addresses the testing and certification standards for fire doors.

The main items include materials, accessories, processing technology and appearance quality, door leaf quality, dimensional tolerance, geometric tolerance, fit tolerance, and related tests.
