1 Scope
This clause of Part 1 is replaced as follows:
1.1 This Part 2 applies to automatic electrical temperature sensing controls
for use in, on or in association with equipment for household and similar use,
including electrical controls for heating, air-conditioning and similar
applications. The equipment may use electricity, gas, oil, solid fuel, solar
thermal energy, etc. or a combination thereof.
1.1.1 This Part 2 applies to the inherent safety, to the operating values,
operating times, and operating sequences where such are associated with
equipment safety. It applies also to the testing of automatic electrical
control devices used in, or in association with, household or similar
appliances.
Examples of such controls include boiler thermostats, fan controls, temperature
limiters and thermal cut-outs.
This Part 2 does not apply to automatic electrical controls designed
exclusively for industrial applications.
This Part 2 is also applicable to individual controls utilized as part of a
control system or controls which are mechanically integral with multifunctional
controls having non-electrical outputs.
1.1.2 This Part 2 also applies to the electrical safety of temperature sensing
controls with non-electrical outputs such as refrigerant flow and gas controls.
1.1.3 This Part 2 is also applicable to controls for appliances within the
scope of IEC 335.
Throughout this Part 2 the word "equipment" includes "appliance" and "control
system".
1.1.4 This Part 2 applies to manual controls when such are electrically and/or
mechanically integral with automatic controls.
Requirements for manual switches not forming part of an automatic control are
contained in IEC 328.
1.1.5 This Part 2 applies to bi-metallic single operation devices as defined
in this standard.
1.2 This Part 2 applies to controls with a rated voltage not exceeding 660 v
and with a rated current not exceeding 63 A.
1.3 This Part 2 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. Where a response value is of
significant purpose for the protection of the user, or surroundings, the value
defined in the appropriate household equipment standard or as determined by the
manufacturer shall apply.
1.4 This Part 2 applies also to controls incorporating electronic devices,
requirements for which are contained in Appendix H.
