Foreword
Chapter 5, Chapter 6 [except 6.16.4, 6.20.3.8, 6.25, 6.26.1 a] and 6.27.1 a)], Chapter
8 and 10.1.1 are compulsory; the others are voluntary.
This Standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GA 602-2006, Dry chemical fire extinguishing equipment.
Compared with GA 602-2006, the main technical changes of this Standard are as
follows.
-- it modifies the normative references (see Chapter 2; Chapter 2 of 2006);
-- it modifies the definition of dry powder fire extinguishing equipment (see 3.1; 3.1
of Edition 2006);
-- it adds the definition of temperature-actuated magnetic generator (see 3.5), the
definition of stored mechanical energy discharge equipment (see 3.6) and
controlling and activating package (see 3.7);
-- it adds the classification method for the particle size of dry powder fire
extinguishing equipment (see 4.4);
-- it adds the classification method based on the using places where dry powder fire
extinguishing equipment is used (see 4.5; 4.5 of Edition 2006);
-- it modifies the classification method based on the actuating methods of dry
powder fire extinguishing equipment (see 4.6; 4.4 of Edition 2006);
-- it modifies the designation method (see Chapter 5; Chapter 5 of Edition 2006);
-- it modifies the range of working temperature (see 6.1.1; 6.1.1 of Edition 2006);
-- it adds other performance of non-storage-pressure fire extinguishing equipment
(see 6.5.3);
-- it modifies the requirements for the quality deviations of filling of dry powder fire
extinguishing agent (see 6.6; 6.7 of Edition 2006);
-- it adds the damp-heat resistance performance (see 6.7.2.2), vibration resistance
performance (see 6.8.2) and salt spray resistance performance (see 6.9.2) of
special-purpose fire extinguishing equipment;
-- it adds the requirements for the reactions and action times of non-storage-
pressure fire extinguishing equipment (see 6.10);
-- it adds the linkage performance (see 6.11);
