Introduction

Fire extinguishing system to carry out the test is an effective means to evaluate the performance of fire extinguishing systems, fire is an important part of scientific research. But how to determine the fire test according to the characteristics and actual fire scene combustion standard combustion, has been troubled by the fire science technology Surgery problems. When using the actual combustion test was carried out fires, excessive consumption of resources, and because of differences in combustion properties, likely to cause fire Experimental study of data disaster fluctuations, lack of comparability and reproducibility test results, while it is difficult to develop a unified system of fire extinguishing performance The evaluation criteria. Therefore, it is necessary to carry out fire extinguishing systems research and experimental development work using standard criteria of combustion. "Standard for the source of fire extinguishing system fire test of the" 2011 project of the State Administration of Quality nonprofit industry research and special research projects, through Typical properties actually been studied combustion combustion characteristics, developed a fire-extinguishing system Class A fire burning was used in the test, and then build the more Fire tests for scientific and reasonable model for studying the relevant technology and equipment for fire extinguishing system provided critical technical support. This standard is based Class A fire test in a typical actual combustion Combustion Characteristics of research and developed a large number of experimental verification basis. National standard Quasi-extinguishing system in the form of Class A fire test standard combustion parameters and technical requirements to make provisions for the first time in our country. Class A fire extinguishing system with a standard combustion test
