Product Overview

The Apparatus for Testing Resistance to Abnormal Heat of Insulating Sleeves (Plug Pin) – IS 1293 is a specialized laboratory instrument used to determine the thermal endurance and safety of insulating sleeves fitted on plug pins. The test evaluates whether the insulation material deforms, softens, or fails when exposed to high temperature under mechanical pressure, ensuring compliance with Indian Standard IS 1293.

During testing, the specimen is subjected to controlled heating (typically up to 200°C for 30 minutes) while a specified load is applied. This process simulates abnormal operating conditions to verify that the insulating sleeve maintains its shape and protective properties without shrinkage or damage.

Designed with an accurate heating system, stable pressure mechanism, and heat-resistant construction, the apparatus provides consistent and repeatable test results. It is widely used by plug manufacturers, test laboratories, certification agencies, and quality control departments to ensure the safety and reliability of electrical plug and socket products.
