AS 1308-1987

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.
