Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB/T 25998-2010 "Mineral Wool Decorative Acoustic Panel", compared with GB/T 25998-2010, except for editorial changes
The main technical changes outside are as follows.
--- Increased scope of application (see Chapter 1, Chapter 1 of the.2010 edition);
---Modified the definition of mineral wool decorative sound absorption board, wet process board, and dry process board (see 3.1, 3.2, 3.3, and 3.1, 3.2, 3.3 in the.2010 edition);
--- Modified the content of the mark (see 4.3, 4.3 in the.2010 edition);
--- Modified the volume density index (see 5.1.3, 5.3 of the.2010 edition);
--- Modified the combustion performance classification requirements (see 5.1.4, 5.6 of the.2010 edition);
--- Modified the formaldehyde emission index (see 5.1.6,.2010 version 5.10);
---Modified the technical indicators of products with different production processes (see 5.2, 5.3, 5.3, 5.5, 5.6, 5.7, 5.10 in the.2010 edition);
--- Modified the noise reduction coefficient index (see 5.2.2, 5.3.2, 5.7 in.2010 version);
--- Modified the bending failure load index of rock wool substrate dry method board (see 5.3.1, 5.5.2 of.2010 edition);
--- Modified the test method of right angle deviation (see 6.2, 6.2 in.2010 version);
--- Modified the noise reduction coefficient test method (see 6.7, 6.7 in.2010 version);
--- Modified the formaldehyde emission test method (see 6.10,.2010 version 6.10);
--- Removed Appendix B (see Appendix B of the.2010 edition);
--- Modified the method of valuing the bending failure load of dry method plates (see C.5.6,.2010 version of C.5.6).
