Foreword
Article 4 and Article 6 of this Part are compulsory; the others are voluntary.
GB 4066, Fire Extinguishing Media, is divided into two parts.
-- Part 1. BC Powder;
-- Part 2. ABC Powder.
This Part is Part 2 of GB 4066. This Part is nonequivalent to ISO 7202.1987, Fire
Protection – Fire Extinguishing Media – Powder, and the major difference between
them are as follows.
-- some modifications in formatting are made in accordance with the Chinese
language codes;
-- some expressions applicable to international standards are changed into those
applicable to Chinese standards;
-- the requirements for moisture content, moisture absorption and color are added;
-- the test methods for fire extinguishing performance are modified;
-- Annex A “Ammonium Dihydrogen Phosphate Content Test Method” and Annex B
“Flowability Test Method” are added.
This Part replaces GB 15060-2002, Ammonium Phosphate Fire Extinguishing Powder.
In addition to the reference of ISO 7202-1987, this revision is made by referencing
United States Federal Specification O-D-1380B 1990.12 Ammonium Phosphate Fire
Extinguishing Powder and the third part of Malaysian standard MS 1180 1990 Fire
Extinguishing Media – Part 3 – Specification for Powder.
Compared with GB 15060-2002, the major changes of this Part are as follows.
-- the requirements for color and discharge performance are added;
-- the requirements for content, density and grain size distribution are modified;
-- the test methods for moisture content and fire extinguishing performance are
modified;
-- the normative annex “Ammonium Dihydrogen Phosphate Content Test Method”
is added (see Annex A);
-- the informative annex “Flowability Test Method” is added (see Annex B).
From the date of implementation of this Part, GB 13532-1992 General Specifications
