Foreword
Clauses 5.1.5, 5.2 and 7 of this standard are mandatory and the rest are recommended.
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB 14907-2002 "Steel Structure Fire Retardant Coatings".
Compared with GB 14907-2002, the main technical changes of this standard except for editorial changes are as follows.
--- Increased terms and definitions of section coefficients (see 3.2);
--- Revised the classification and model of the product (see Chapter 4; Chapter 4 of the.2002 edition);
--- Revised the general requirements of the product (see 5.1; 5.1 of the.2002 version);
--- Increased insulation efficiency deviation requirements and test methods (see 5.2, 6.4.7);
--- Increased pH requirements and test methods (see 5.2, 6.4.8);
--- Modified water resistance, cold and heat cycle resistance, heat resistance, heat and humidity resistance, freeze-thaw resistance, acid resistance, alkali resistance, salt spray resistance
Corrosion, fire resistance requirements and test methods (see 5.2, 6.4.9, 6.4.10, 6.4.11, 6.4.12, 6.4.13, 6.4.14, 6.4.15,
6.4.16, 6.5; 5.2, 6.4.8, 6.4.9, 6.4.10, 6.4.11, 6.4.12, 6.4.13, 6.4.14, 6.4.15, 6.5) of the.2002 edition;
--- Revised the preparation of physical and chemical properties test pieces (see 6.3;.2002 version 6.3);
--- Increased UV radiation resistance requirements and test methods (see 5.2, 6.4.17);
--- Removed additional fire resistance (see 6.6 of the.2002 edition);
--- Revised inspection rules (see Chapter 7; Chapter 7 of the.2002 edition);
--- Increased insulation efficiency test for steel structure fire retardant coatings (see Appendix A);
--- Revised the calculation of the fire test load of steel structure fire retardant coating (see Appendix B; Appendix A of the.2002 edition);
--- Removed the assessment of the corrosion resistance of steel fire retardant coatings (see Appendix B of the.2002 edition).
