Including Mechanical Requirements (IEC 60730-2-19, IDT).
This Part equivalently adopted IEC 60730-2-7:2008 Automatic Electrical Controls for
Household and Similar Use - Particular Requirements for Timers and Time Switches
(Version II).
The structure of this Part was completely the same as IEC 60730-2-7:2008. In this Part,
if there are the corresponding national standards, refer to the national standards; while
if there are not the corresponding national standards temporarily, refer to the listed IEC
standards.
For the benefit of the use, this Part do the following editorial changes:
a) Use decimal point “.” to replace the comma “,” that acts as the decimal point;
b) Add the foreword of the national standard;
c) Replace “this Standard” by “this Part”;
d) Use “GB 14536.1” to replace “Part 1”.
This Part was used together with GB 14536.1-2008 Automatic Electrical Controls for
Household and Similar Use – General Requirements.
This Part replaced GB 14536.8-1996 Automatic Electrical Controls for Household and
Similar Use - Particular Requirements for Timers and Time Switches.
Compared with GB 14536.8-1996, this Part has the major changes as follows:
a) Modify the names of server clauses and sub-clauses according to the changes
of GB 14536.1;
b) Adjust the limit of 1.1, 1.1.1, 1.1.2 in Clause 1 Scope; add 1.1.3 and 1.1.4
replacement; correspondingly adjust 1.2 rated voltage range; add 1.5 normative
references;
c) Add the content of 6.5.101 in Clause 6;
d) Add modification against the Table 17.2-1 in Clause 17 Durability; China also
uses overvoltage test to replace overload test; significantly adjust 17.16, also
adjust some standard data;
e) Delete the addition contents in Clause 20 Creepage Distance, Clearance and
Distances through Solid Insulation;
f) Add Clause 28 Guidance on the Use of Electronic Disconnection;
g) Change the value in D.101.2.3 of Appendix D;
h) Add Appendix H.
The Appendix D, Appendix H, and Appendix AA of this Part are normative one.
This Part was proposed by China Electrical Equipment Industrial Association.

Automatic Electrical Controls
for Household and Similar Use -
Particular Requirements for Timers and Time Switches
1 Scope and Normative References
This clause of GB 14536.1 is applicable except as follows:
1.1 Replacement:
In general, this Part applies to timers and time switches for household and similar use
that may use electricity, gas, oil, solid fuel, solar thermal energy, etc. or a combination
thereof, including heating, air conditioning and similar applications.
This Part is also applicable to individual timers utilized as part of a control system or
timers which are mechanically integral with multifunctional controls having non-
electrical outlets. This Part does not apply to time-delay switches (TDS) within the
scope of GB 16915.41).
NOTE: Throughout this Part, the word “timers” means timers and time switches, unless the type
is specifically mentioned.
Devices which only indicate time or passage of time are not included.
This Part does not apply to multi-functional controls having an integrated timing function which
is not capable of being tested as a separate timing device.
1.1.1 This Part applies to the inherent safety, to the operating characteristics where
such are associated with equipment protection and to the testing of automatic electrical
control devices used in appliances and other apparatus, electrical and non-electrical,
for household and similar purposes, but also extended to industrial purposes when no
dedicated product standards exist, such as that for central heating, air conditioning,
process heating, etc.
Timers for equipment not intended for normal household use, but which nevertheless
may be used by the public, such as equipment intended to be used by laymen in shops,
in light industry and on farms, are within the scope of this Part.
This Part is also applicable to timers for appliances within the scope of GB 4706.1.
This Part does not apply to timers designed exclusively for industrial applications.
