Foreword
This standard 4.4, 4.5, Chapter 6, 7.1 is mandatory, and the rest are recommended.
This standard replaces GA 160-1997 "General Technical Conditions for Non-combustible Inorganic Composite Panels" from the date of implementation.
The main differences between this standard and GA 160-1997 are as follows. the thermal dimensional shrinkage and hygroscopic sagging in GA 160-1997 are eliminated.
Requirements for composite (sandwich) materials in degree and combustion performance; increased dimensional deviation requirements and density of plates with density greater than 1.50 g/cm3
The flexural strength requirements of 1.75g/cm3 sheet and the anti-returnability requirement of glass magnesium plate; the index and test of adjusting the moisture absorption rate
method.
The combustion performance of this standard is mainly based on GB 8624-1997 "Classification Method of Combustion Performance of Building Materials";
ISO /T R1896.1991 "Incombustible and fire-retardant fiber reinforced calcium silicate board or cement board", CNS13778A3357
Chemical Cement Board Inspection Method, CNS13777A2266 "Fiber Strengthened Cement Board".
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.
This standard was drafted. Sichuan Fire Science Research Institute of the Ministry of Public Security, Guangzhou Yayuan Environmental Protection Materials Co., Ltd.
