Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 25261-2010 "reflective thermal insulation coating for construction", compared with GB/T 25261-2010, except for editorial repair
The main technical changes changed are as follows.
--- Revised the scope of the standard (see Chapter 1, Chapter 1 of the.2010 edition);
--- "GB/T 9271, GB/T 13491" in the normative reference documents were changed to "GB/T 9271-2008, GB/T 13491-
1992"; added normative references "GB/T 1728-1979, GB/T 1733-1993, GB/T 1766-2008,

The normative reference document "GJB2502-1996" (see Chapter 2, Chapter 2 of the.2010 edition);
--- Added classification (see Chapter 4);
--- Increased the functional requirements and test methods for paints in heat insulation (see 5.1.1, 6.4.2 and Appendix A);
--- Increased the division of the brightness range of the reflective heat-insulating flat topcoat (see 5.1.2);
--- Revised the solar reflectance, hemispheric reflectance index and test method of reflective heat-insulating flat topcoat (see 5.1.2, 6.4.3,
6.4.5, 4.1, 5.4, 5.5) of the.2010 edition;
--- Increased the near-infrared reflectance of the reflective heat-insulating flat topcoat, the rate of change of the solar reflectance after contamination, and the thermal insulation temperature of the reference blackboard
Differential test items, indicators and test methods (see 5.1.2, 6.4.4, 6.4.6, 6.4.7, Appendix B);
--- Added functional requirements, basic performance requirements and test methods for reflective heat-insulating topcoats (see 5.1.3, 6.3.4, 6.4.3,
6.4.4, 6.4.5, 6.4.6, 6.4.7, Appendix B);
--- Increased the basic performance requirements and test methods for paints in heat insulation (see 5.2.1, 6.4.8, 6.4.9, 6.4.10, 6.4.11, 6.4.12,
6.4.13, 6.4.14, 6.4.15, 6.4.16, 6.4.17, 6.4.18, 6.4.19);
--- Increased basic performance requirements for reflective heat-insulating flat topcoats (see 5.2.2);
--- Removed Appendix A "Equivalent Coating Thermal Resistance Calculation Method" (see Appendix A of the.2010 edition).
