GA 98-1995Fire resistive coating for concrete structure (English PDF)

Foreword

Chapters 5, 6, and 7 of this standard are mandatory, and the rest are recommended.

This standard replaces GA 98-1995 "General Technical Conditions for Prestressed Concrete Floor Fireproof Coatings" from the date of implementation.

The main difference between this standard and GA 98-1995 is that the thermal conductivity requirements are eliminated; the performance requirements of tunnel fire retardant coatings are increased.

experiment method. The test modification for the fire resistance of tunnel fire retardant coatings was carried out using BSEN1363-2:1999 Fireresistance tests-Part 2. Alternativeandadditionalprocedures "Fire Test Part 2. Optional Programs and Additional Programs" and GT-9806398-CVB-R1161FIREPROTECTIONFORTUNNELSPart 1. firetestprocedureforimmer-Sedtunnels "Tunnel Fire Protection Part I. Fire Test Procedure for Buried Tunnels" was formulated.

Appendix A of this standard is a normative appendix.

This standard was proposed by the Fire Department of the Ministry of Public Security.

This standard is under the jurisdiction of the 7th Technical Committee of the National Fire Protection Standardization Technical Committee.

1 Scope

This standard specifies the definition and classification of concrete structure fireproof coatings, requirements, test methods, inspection rules and signs, packaging, transportation, Storage.

This standard applies to fireproof coatings on concrete surfaces such as industrial and civil buildings and roads, railways (including subway) tunnels.
