BIS CERTIFICATION FOR THERMOSTAT METAL SHEET AND STRIP IS 5478:1969

Thermostat metal sheets and strips are thin pieces of metal with unique qualities for thermostats. These sheets and strips help control the temperature by bending or moving when the temperature goes up or down. They can change shape with temperature shifts, helping control temperature in different devices and systems.

To ensure the product quality of these thermostat metal sheet and strip, the Bureau of Indian Standards (BIS) has made it mandatory for manufacturers to undergo BIS registration and obtain the BIS ISI mark before selling it in the market. Manufacturers can use the ISI Mark on their products only after obtaining a license from BIS that is granted after BIS registration. The presence of the ISI mark on a product indicates that it complies with BIS's stringent quality standards.

IS 5478:1969 covers the thermostat metal sheet and strip. This standard specifies the general requirements for thermostat metal in sheet and strip form. Thermostat metal is a composite material, usually in the form of a sheet or strip, made up of two or more materials of any appropriate nature, metallic, or otherwise, that tend to change curvature when the temperature is changed due to the differing coefficients of linear expansion of the components.

By including material constants such as chemical composition and physical properties, this standard can also be used as a guide in preparing detailed specifications for various specified types of thermostat metals.

TEST REQUIREMENTS OF IS 5478: 1969
