GB 14536 Automatic Electrical Controls for Household and Similar Use can be divided into the following two parts: --- Part 1: General Requirements; --- Part 2: Particular Requirements. The Particular Requirements consist of the following parts: --- GB 14536.3 Particular Requirements for Thermal Motor Protectors (IEC 60730- 2-2, IDT); --- GB 14536.4 Particular Requirements for Thermal Protectors for Ballasts for Tubular Fluorescent Lamps (IEC 60730-2-3, IDT); --- GB 14536.5 Particular Requirements for Thermal Motor Protectors for Motor – Compressors of Hermetic and Semi-Hermetic Type (IEC 60730-2-4, IDT); --- GB 14536.6 Particular Requirements for Automatic Electrical Burner Control Systems (IEC 60730-2-5, IDT); --- GB 14536.7 Particular Requirements for Automatic Electrical Pressure Sensing Controls Including Mechanical Requirements (IEC 60730-2-6, IDT); --- GB 14536.8 Particular Requirements for Timers and Time Switches (IEC 60730- 2-7, IDT); --- GB 14536.9 Particular Requirements for Electrically Operated Water Valves Including Mechanical Requirements (IEC 60730-2-8, IDT); --- GB 14536.10 Particular Requirements for Temperature Sensing Controls (IEC 60730-2-9, IDT); --- GB 14536.11 Particular Requirements for Motor-Starting Relays (IEC 60730-2- 10, IDT); --- GB 14536.12 Particular Requirements for Energy Regulators (IEC 60730-2-11, IDT); --- GB 14536.13 Particular Requirements for Electrically Operated Door Locks (IEC 60730-2-12, IDT); --- GB 14536.15 Particular Requirements for Humidity Sensing Controls (IEC 60730-2-13, IDT); --- GB 14536.16 Particular Requirements for Electric Actuators (idt IEC 60730-2- 14); --- GB 14536.17 Particular Requirements for Automatic Electrical Water Level Sensing Controls of The Float or Electrode-Sensor Type Used (IEC 60730-2-15, IDT); --- GB 14536.18 Particular Requirements for Automatic Electrical Water Level Controls of the Float Type for Household and Similar Applications (IEC 60730-2- 16, IDT); --- GB 14536.19 Particular Requirements for Electrically Operated Gas Valves Including Mechanical Requirements (IEC 60730-2-17, IDT); --- GB 14536.20 Particular Requirements for Automatic Electric Water and Air Flow Sensing Controls Including Mechanical Requirements (IEC 60730-2-18, IDT); --- GB 14536.21 Particular Requirements for Electrically Operated Oil Valves 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. This Part shall be under the jurisdiction of National Technical Committee for Standardization of Automatic Electric Control for Household (SAC/TC 212).

The historical edition replaced by this Part is as follows: --- GB 14536.8-1996. 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. 1) GB 16915.4-2003: Switches for Household and Similar Fixed Electrical Installations – Part 2-3: Particular Requirements – Time-Delay Switches (TDS) ......
