Foreword
Chapter 4 of this Standard is mandatory, while the rest are recommended.
Consistency BETWEEN this Standard AND ISO 7203-1.1995(E) “Extinguishing Agent -
Foam Concentrate - Low-expansion Foam Concentrate Used for Water-insoluble Liquid
Fuel Top Application”, ISO 7203-2.1995(E) “Extinguishing Agent Foam Concentrate -
Medium and High-expansion Foam Concentrate Used for Water-insoluble Liquid Fuel Top
Application” and ISO 7203-3.1999(E) “Extinguishing Agent Foam Concentrate -
Low-expansion Foam Concentrate Used for Water-insoluble Liquid Fuel Top Application”
are non-equivalent.
This Standard replaces GB 15308-1994 “General Specification for Foam Extinguishing
Agents”, GB 17427-1998 “Aqueous Film Forming Foam Extinguishing Agent”, and GB
13463-1992 “Alcohol Resistant Foam Extinguishing Agent”.
Compared with GB 15308-1994, the main changes of this Standard are as follows.
-- Add technical requirements and test methods of “Foam Extinguishing Agent for
Foam Extinguishers”;
-- Add technical requirements and test methods of “corrosion performance” and
“freezing point”;
-- Add the definitions of “lowest useful temperature”, “characteristic values”, “25%
drainage time”, “50% drainage time”, “expansion”, “foam”, “foam solution”,
“sediment”, “spreading coefficient” and “anti-burning time”;
-- Delete the definition of “temperature-sensitive foam solution”;
-- Add Annex A “small fire fighting test for foam performance and fire extinguishing
performance quality control” and Annex B “viscosity test method”.
-- Add the division of disqualification types of items;
-- Revise fire extinguishing test procedures and dividing the grades of fire extinguishing
performances of foams.
GA 31-1992 “High-expansion Foam Extinguishing Agent” and GA 219-1999 “Protein
Foam Concentrate and Fluoroprotein Foam Concentrate” shall be abolished, from the
date of implementation of this Standard.
Annex B to this Standard is normative; Annex A is informative.
This Standard was proposed by Ministry of Public Security of the People’s Republic of
China.
This Standard shall be under the jurisdiction of Third Branch Technical Committee of
National Fire Fighting Standardization Committee.
Drafting organizations of this Standard. Tianjin Fire Research Institute, Ansul, Ningbo
Nenglin Fire-fighting Equipment Co., Ltd. AND Yangzhou Jiangya Fire Extinguishing
Agents Co., Ltd.
