25、ime switches 1 Scope and normative references This clause of Part 1 is applicable except as follows: 1.1 Replacement: In general, this part of IEC 60730 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 c
26、ombination thereof, including heating, air conditioning and similar applications. This standard 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 standard does not a
27、pply to time-delay switches (TDS) within the scope of IEC 60669-2-31). Throughout this standard, 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 standard does not apply to multi-fu
28、nctional controls having an integrated timing function which is not capable of being tested as a separate timing device. 1.1.1 This standard applies to the inherent safety, to the operating characteristics where such are associated with equipment protection and to the testing of automatic electrical
29、 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 equipme
30、nt 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 standard. This standard is also applicable to timers for appliances within the scope of I
31、EC 60335-1. This standard does not apply to timers designed exclusively for industrial applications. Throughout this standard, the word “equipment“ means “appliance and equipment“. 1.1.2 This standard applies to automatic electrical control devices, mechanically, electromechanically, electrically or
32、 electronically operated, responsive to or controlling parameters such as temperature, pressure, passage or time, humidity, light, electrostatic effect, flow or liquid level. _ 1)IEC 60669-2-3:2006, Switches for household and similar fixed electrical installations Part 2-3: Particular requirements T

34、n appliances and apparatus for household and similar purposes. Such control devices may be built into or be separate from the motor. 1.1.4 This standard applies to non-automatic control devices when such are associated with automatic control devices. 1.2 Replacement: This standard applies to control
35、s with a rated voltage not exceeding 690 V and a rated current not exceeding 63 A. 1.3 Replacement: This standard does not take into account the response value of an automatic action of a control, if such a response value is dependent upon the method of mounting the control in the equipment. If a re
36、sponse value is of significant purpose for the safety of the user or surroundings, the value defined in the appropriate household equipment standard or as determined by the manufacturer shall apply. 1.4 Replacement: This standard applies also to timers incorporating electronic devices, requirements
