Applies to multi-heat switches, energy regulators, and thermostats, including those for ovens, hot-plates and rotisseries. Design, construction and marking requirements and a detailed section on performance testing are included. Appendices include standard dimensions and fixing arrangements and determination of thermostat operating temperature and differential.

This standard specifies requirements for multiheat switches, energy regulators and thermostats (including those for oven, hotplate and rotisseries) intended for use in the control of heating units in household electric ranges.The standard includes definitions, requirements relating to construction, performance requirements and methods of testing.
