Specifies revised terminology and requirements for thermostats, thermal cutouts (TCOs) and combined units; also a clip template to provide interchangeability between clip-mounted units. Provides guidance on temperature settings and introduces the concept of 'scale offset' to allow for differences between the specified standard test tank and the water heater to be controlled. A minimum cut-out temperature of 60 degrees Celsius is specified on health grounds.

This Standard specifies the performance and corresponding test requirements for thermostats, for non-self- resetting thermal cutouts, and for combinations thereof, intended for use in storage water heaters (see AS 1056), including the heat exchange type (see AS 1361), those with solar input (see AS 2712), and those for use in dairies (see AS 2123).For immersion thermostats, the Standard specifies a pocket to suit an 8 mm diameter stem.While this Standard is written around electromechanical devices, other devices, e.g. solid state, are not excluded.NOTES:1. Throughout this Standard, the term 'non-self-resetting thermal cutout' is abbreviated to TCO. (The plural is TCOs).2. For special purposes, additional requirements would need to be specified, e.g. a high temperature setting for dairy water heaters; a low temperature differential for close control of temperature.3. In order to facilitate the specification and purchase of thermostats and TCOs, information which should be supplied with enquiry and order is given in Appendix A.
