Introduction

Since the promulgation GA 500-2004 GA 499.1-2004 and promote the technological development of aerosol fire extinguishing system, also contributed to the relative Off the technical specifications such as GB 50370-2006 "gas fire extinguishing system design specifications" and GB 50263-2007 "gas fire extinguishing system installation and inspection Income standard "revision. In recent years, the product from the technical level, application areas, product type, product performance and other aspects have great hair Exhibition, change and improve. International International Organization for Standardization (ISO ), National Fire Protection Association (NFPA), such as Underwriters Laboratories (UL) Etc. have been published in recent years or are developing standards for this product. GA 499.1-2004 and GA 500-2004 two standard focal point National Standardization Technical Committee fixed fire extinguishing systems and fire extinguishing agents Technical Committee Technical Committee based on the characteristics of the product, in After extensive consultation with the manufacturer, design units, the use of units, management advice, consultation will integrate the two criteria, after the integration of content standards Unified into Part 1 GA 499 standard, and part of the status quo and change the foreign standard products to conduct a comprehensive Amendments.

In order to meet technological development thermal aerosol fire extinguishing devices, ensure the safety of its use, the technical content of the standard made the following changes.

1) for S and K-type aerosol fire extinguishing agent has been re-defined. This revision changes the GA 499.1-2004 press aerosols Extinguishing agent generator chemical components were divided in principle, but the performance of aerosol fire extinguishing agent as a division of S-type gas Sol extinguishing agent, K-type aerosol fire extinguishing agent basis. Because overcome by the chemical composition of division brings a wide variety of applications Marketing costs and the use of excessive administrative inconvenience.

2) Categories of non-limiting temperature increase fire suppression devices. Depending on the needs of place, this type of fire extinguishing system can reduce the coolant it uses, reducing the quality of the device itself, extinguishing effect some improvement.

3) aerosol fire extinguishing agent generating agent maximum filling quality limits. In recent years, through the thermal aerosol fire extinguishing apparatus for detecting data and analysis of the state of the discharge from the safety and aerosol fire extinguishing agent occurs extinguishing apparatus for use in fire fighting can be fully Combustion reaction and many other considerations, to determine the aerosol fire extinguishing agent generating agent maximum filling quality.

4) technical requirements for aerosol fire extinguishing agent and heat generating agent aerosol fire extinguishing agent can be adjusted. From a storage product performance, safety Aspects of energy, corrosion, etc. on the 2004 version of the standard was revised and supplemented.

5) from the environmental requirements of the material and coolant cooling device is proposed in line with national environmental requirements of the regulations.
