Foreword
This Standard was drafted according to the rules specified in GB/T 1.1-2009.
This Standard replaces CJ/T 3074-1998 Electronic Controller of Household Gas Burning
Appliances.
This Standard is the revision of CJ/T 3074-1998 Electronic Controller of Household Gas
Burning Appliances, and the main technical changes, compared with CJ/T 3074-1998,
are as follows.
a) ADD the controller classification, DELETE the content of “model number” (see
Chapter 4, Chapter 4 in 1998 version);
b) SUPPLEMENT the controller structure design requirements and circuit structure
requirements for internal fault protection (see Chapter 5; 5.3 in 1998 version);
c) SUPPLEMENT the electrical safety and electromagnetic compatibility requirements
(see 6.5, 6.6, Chapter 5 in 1998 version);
d) MODIFY the requirements for controller function and divided into different modules
requirements according to function (see 6.1, 5.1, 5.2 in 1998 version);
e) MODIFY the requirements for thermal stress, continuous operating performance
and internal fault protection (see 6.2, 6.3, 6.4; 5.1 in 1998 version);
f) MODIFY the special requirements for “battery-powered controller” (see Annex H,
Chapter 5 in 1998 version);
g) DELETE the “salt fog test” and “vibration resistance test” (see 5.1 in 1998 version).
In order to maintain consistency with GB 16914-2012 Technical Condition for Safety of
Gas Burning Appliances, this Standard provides corresponding table in Annex J to show
those provisions in this Standard that support basic requirements of GB 16914-2012.
This Standard was proposed by Standard Rating Institute of Ministry of Housing and
Urban-rural Development.
This Standard is under jurisdiction of Gas Technical Committee for Standardization of the
Ministry of Housing and Urban-rural Development.
