The #thermostat is a composite material, usually in the form of a sheet and strip, made up of two or more #metallic layers with different expansion coefficients. When permanently bonded together with the change of temperature, the dimensions of the product completely change. This change of curvature or bending in response to temperature change (reflexivity) is a fundamental property of each thermostat metal. IS 5478: 1969 covers the thermostat metal sheet and strip. This Indian standard specifies the general requirements for thermostat #metal in sheet and strip form. This standard can also be used as a guide in preparing detailed specifications for several specified kinds of thermostat metals by including material constants like physical properties and chemical composition.
