Foreword
Subclause 7.2 of Clause 5 of this Standard is compulsory; other clauses
of this Standard are voluntary.
This Standard replaces GB 12955-1991 “General technical conditions for steel
fire door” and GB 14101-1993 “Wood fire door - General technical conditions”.
Compared with GB 12955-1991 and GB 14101-1993, the major changes are
as follows:
- ADD the content of the classification of fire resistant doorsets according to
material (see 4.1);
- MODIFY the classification of fire resistance of fire resistant doorsets, from
the original A, B, C to fully insulated doorsets (type A), partially insulated
doorsets (type B) and no insulated doorsets (type C) (4.3 in GB 12955-
1991, 4.1 in GB 14101-1993 and 4.4 of this Standard);
- Requirement for the material of fire resistant doorsets is more specific: apart
from non-metallic material, ADD the requirements for combustion
performance and burning flue-gas toxicant (5.1 in GB 12955-1991 and GB
14101-1993 and 5.2 in this Standard);
- DELETE the requirements of wind pressure deformability resistance, air
penetration resistance and rainfall penetration resistance for fire resistant
timber doorsets used as the building exterior door;
- Performance requirements for fireproof locks are more specific (5.1.3 in GB
12955-1991, 5.1.4 in GB 14101-1993 and 5.3.1 of this Standard);
- Performance requirements for fireproof hinges (gemels) are more specific
(5.1.3 and 5.1.4 in GB 12955-1991, 5.1.4 in GB 14101-1993 and 5.3.2 of
this Standard);
- Performance requirements for door-closing devices are more specific (5.1.3
in GB 12955-1991, 5.1.4 in GB 14101-1993 and 5.3.3 of this Standard);
- Performance requirements for fire resistant glass are more specific (5.1.3
in GB 12955-1991, 5.1.3 in GB 14101-1993 and 5.3.7 of this Standard);
- ADD the quality requirements and test methods for the door leaf of fire
resistant doorsets (see 5.5 and 6.6);
- ADD the requirements and test methods for the degree of curvature in the
width direction of the door leaf (see 5.7 and 6.8.3);
Fire resistant doorsets
1 Scope
This Standard specifies the classification, code and tag, requirements, test
methods, inspection rules, marking, packaging, transportation and storage of
fire resistant doorsets.
This Standard is applicable to fire resistant timber, steel and timber-steel side
hung doorsets and other material fire resistant. As for fire resistant doorsets of
other open modes, it may refer to this Standard.

3.3
fire resistant steel doorsets
Doorsets with certain fire resistance, of which the door frame, door leaf frame
and door leaf panel are made of steel material. If the door leaf is filled with
materials, it will be filled with fireproof and heat-insulating materials that are
non-toxic and harmless to the human body. It is equipped with fire-resistant
hardware components.
3.4
fire resistant timber doorsets with steel structure
Doorsets with certain fire resistance, of which the door frame, door leaf frame
and door leaf panel are made of steel and flame-retardant wood or flame-
retardant wood products. If the door leaf is filled with materials, it will be filled
with fireproof and heat-insulating materials that are non-toxic and harmless to
the human body. It is equipped with fire-resistant hardware components.
3.5
other material fire resistant doorsets
Doorsets with certain fire resistance, of which the door frame, door leaf frame
and door leaf panel are made of inorganic non-combustible materials other than
steel, flame-retardant wood or flame-retardant wood products or partially made
of steel, flame-retardant wood, and flame-retardant wood products. If the door
leaf is filled with materials, it will be filled with fireproof and heat-insulating
materials that are non-toxic and harmless to the human body. It is equipped
with fire-resistant hardware components.
3.6
fully insulated doorsets
Within a specified period of time, doorsets that meet the requirements for fire
integrity and fire insulation.
3.7
partially insulated doorsets
Doorsets that meet the requirements for fire integrity and fire insulation within
a specified period of time greater than or equal to 0.50 h, and meet the
requirements for fire integrity when 0.50 h is exceeded.
