Thermostat metal is a composite material made of many metallic layers with varying expansion coefficients that is frequently shaped like sheets and strips. The result has major dimensional variations when these layers are firmly bonded together and exposed to temperature fluctuations. Reflexivity, the term for this shape or flexure change brought on by temperature variations, is a feature that every thermostat metal possesses by nature.
Specialized materials called thermostat metal sheets and strips are used to make thermostats and other temperature control devices. Their capacity to minimize energy efficiency, maintain safety, improve equipment lifetime, and react reliably to temperature changes makes them essential to a wide range of systems, from industrial machinery and electronics to HVAC and appliances.
According to IS standard IS 5478:1969, all thermostat metal sheets and strips are now a part of the required ISI Certification Scheme.
The criteria for thermostat metal sheets or strips meant to be used as temperature-sensitive parts in devices meant to regulate, adjust, or signal temperature are described in this standard. The maximum sensitivity range, suggested maximum temperature, flexibility, electrical resistivity, elasticity modulus, specific heat, density, and hardness are only a few of the physical specifications that the metals must meet.
Without the ISI Mark, this product cannot be marketed, imported, or exported into the Indian consumer market.
Indian Standards Institute, or ISI was renamed the Bureau of Indian Standards (BIS) in 1987. The official mark that the Bureau of Indian Standards provides for manufacturers of various goods is the ISI Mark. It is used to indicate compliance with Indian standards (IS) set by the Bureau of Indian Standards (BIS) and has been used as a conformity marking for industrial products. Manufacturers received permission from BIS to use the ISI Mark on items that comply with relevant Indian requirements through the product certification program.
Only manufacturers (domestic or foreign) who produce the finished product will be awarded ISI Certification. This will not be given to any product importers, traders, dealers, or distributors.

There are two approaches for Indian manufacturers to become certified with the ISI Mark:
Regular Procedure
With the possible exception of cases deemed "All India first," which might take up to 180 days, the licensing procedure is expected to be finished in 120 days. This timeline starts on the day the application is received, assuming that at different points in time the documentation, unit assessment, and product conformance are all deemed acceptable.
Step 1: Manufacturing Unit Customization in Compliance with Applicable Indian Standards
Step 2: Submission of the Application Form

Simplified Procedure
This is a much faster process than the standard procedure. After a factory inspection is deemed satisfactory and the initial evaluation establishes that the sample complies with the applicable Indian Standard(s), the license application process is expected to be finished in 30 days.
Step 1: Adapting the Manufacturing Unit to Comply with the Relevant Indian Standard
Step 2: Sample Testing
