GB17835—1999
Water-based fire extinguishing agents are a type of fire extinguishing agent that has been developed in my country in recent years. Due to the low price and high fire extinguishing efficiency of this type of fire extinguishing agent, it has been paid attention to by the domestic fire protection industry. In order to ensure the product quality, supervision and testing of this type of fire extinguishing agent, this standard is specially formulated as a unified technical basis. The main technical content of this standard includes the technical requirements and test methods for the physical properties and fire extinguishing performance of water-based fire extinguishing agents. This standard is proposed by the Ministry of Public Security of the People's Republic of China. This standard is under the jurisdiction of the Third Subcommittee of the National Fire Protection Standardization Technical Committee. This standard is drafted by the Tianjin Fire Science Research Institute of the Ministry of Public Security. The main drafters of this standard are: Ren Xuewen, Wang Ya, Dai Guihong, and Wang Yi. This standard is interpreted by the Tianjin Fire Science Research Institute of the Ministry of Public Security. 523

The metal bracket is made of 50mm×50mm equilateral angle steel, and its length×width×height is 500mm×500mm×250mm. The wood strips should be dried to keep their moisture content at 10%~14% (the temperature during drying should not be higher than 105C). The density of the wood strips should be 0.45~～0.55g/cm2 when the moisture content is 12%. The cross section of the wood strips is square, the side length is 39mm±1mm, and the length dimension deviation is ±10 mm.
The wood strips are stacked in layers. The upper and lower layers of wood strips are stacked at right angles, and the wood strips in each layer should be evenly spaced. The test model is a square wood pile with a side length equal to the length of the wood strips. The edges of the wood strips of the test model should be fixed together to prevent them from being dispersed by the fire extinguishing agent during the test. The test model for igniting Class A fire is gasoline for automobiles.
The size parameters of the model are shown in Table 2.
