Foreword
Clause 6 and Clause 8 of this Standard are mandatory. The rest are
recommendatory.
This Standard replaces GB 16807-1997 "Fire intumescent seals".
Compared with GB 16807-1997, the main changes in this Standard are as
follows.
- modified the classification method of structure type, from Type A, Type B,
Type C of the previous edition to Type A, Type B of this Standard (4.1 of
Edition 1997; 5.1 of this Edition);
- modified the requirements and test methods for "swelling performance"
(6.3, 7.3 of Edition 1997; 6.3, 7.3 of this Edition);
- added the requirements and test methods for "toxicity of smoke
generation", "smoke density", "air aging resistance", "cyclizing resistance
to freezing and thawing" (see 6.4, 6.5, 6.6, 6.10, 7.4, 7.5, 7.6, 7.10 of this
Edition);
- modified the performance requirements and test methods for "water
resistance", "acid resistance", "alkali resistance" (6.5.1, 6.5.2, 6.5.3 of
Edition 1997; 6.7, 6.8, 6.9, 7.7, 7.8, 7.9 of this Edition);
- modified "anti-smoking performance" to "fireproof sealing performance",
and improved corresponding performance requirements and test methods
(6.6, 7.8 of Edition 1997; 6.11, 7.11 of this Edition);
- deleted the requirements such as "initial expansion temperature", "bulk
expansion temperature", "linear expansion ratio", "high temperature
resistance and combustion performance", "physical and mechanical
properties" and test methods in the previous edition.
Attention is drawn to the possibility that some of the elements of this Standard
may be the subject of patent rights. The issuing authority shall not be held
responsible for identifying any or all such patent rights.
This Standard was proposed by Ministry of Public Security of PRC.
This Standard shall be under the jurisdiction of Eighth Technical Committee of
National Technical Committee on Firefighting of Standardization Administration
of China (SAC/TC 113/SC8).

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
6.8 Acid resistance
6.8.1 The intumescent components of fire intumescent seals shall be subject
to the acid resistance test according to 7.8. After the test, the fire intumescent
seals shall have no obvious dissolution, swelling, powdering, falling off, etc.
6.8.2 After the acid resistance test, the rate of change in the mass of fire
intumescent seals shall not exceed 5%.
6.8.3 The expansion ratio of the intumescent component after acid resistance
test shall not be less than the initial expansion rate .
6.9 Alkali resistance
6.9.1 Perform alkali resistance test according to the method specified in 7.9.
After the test, the fire intumescent seals shall have no obvious dissolution,
swelling, powdering, falling off, etc.
6.9.2 After the alkali resistance test, the mass change rate of the intumescent
component shall be no more than 5%.
6.9.3 The expansion ratio of the intumescent component after alkali
resistance test shall not be less than the initial expansion rate .
6.10 Freeze-thaw cycle resistance
6.10.1 Perform the freeze-thaw cycle resistance test according to the method
specified in 7.10. After the test, observe the intumescent component and press
the surface of the intumescent component with a glass rod, there shall be no
obvious powdering, shedding phenomenon.
6.10.2 The expansion ratio of the intumescent component after freeze-thaw
cycle resistance test shall not be less than the initial expansion rate .
6.11 Fire sealing performance
The fire intumescent seals for fire doors shall be installed on fire doors
according to the installation methods specified in their instructions on use.
Perform the test according to the method specified in 7.11. The fire-resisting
integrity of the fire intumescent seals used in the site shall meet the
