The Lumetron CT 20 Compression Test Apparatus is designed to perform tests specified in many standards where resistance of insulating materials to elevated operating temperatures is to be determined. It is used to test insulation materials used in Electrical Appliances, Electrical wiring accessories, luminaires, motors, connectors, etc. The test ensures that external parts of insulating material, the deterioration of which might cause the appliance to fail to comply with the relevant standards, are sufficiently resistant to heat. Enclosures & other external parts of insulating material are subjected to the test.

The CT-20 compression test apparatus is designed to verify the quality & safety characteristics of products, as required by national & international safety regulatory agencies such as IEC, BIS, UL, CSA, VDE, BSI, DIN, etc. It is a precision engineered test instrument for use by Safety & Compliance Testing Laboratories. The sample to be tested is placed on the fixed jaw & the moving jaw is placed on top of it. The whole assembly is then placed inside an oven & maintained at the test temperature for the specified time period. After the test period, the sample & compression test apparatus are removed from the oven & cooled to room temperature.
