Scope

This standard specifies the basic principles, measuring devices, sample preparation and requirements, test procedures and result calculations, test reports, accuracy and error, etc. for measuring thermal bimetal specific bending, temperature curvature and bending constant. This standard includes test methods for specific bending, temperature curvature, and bending constant of bimetals. The thermal bimetal specific bending test method is applicable to the measurement of the specific bending performance of thermal bimetal strips with a thickness of 0.60 mm to 1.25 mm and a temperature of 20 ° C to 130 ° C. The thermal curvature test method for thermal bimetals is suitable for measuring the thermal curvature of straight thermal bimetals with a thickness of 0.30 mm to 1.25 mm and spiral thermal bimetals with a thickness of less than 0.30 mm. The thermal bimetallic bending constant test method is suitable for measuring the bending constant of thermal bimetallic flat strip specimens with a thickness of 0.25mm to 1.20mm and a temperature range of ~100°C.
