Introduction to the Test

The evaluation for Ex-product is generally divided as document evaluation and test evaluation, and the test evaluation shall be conducted type test for general requirements and each type of protection.

Applied field

Type test for general requirements (IEC 60079-0 & ISO 80079-36)
Thermal tests / Resistance to impact / Drop test / Degree of protection (IP) by enclosures / Thermal endurance to heat / Thermal endurance to cold / Surface resistance test of parts of enclosures of non-metallic materials / Small component ignition test / Torque test for bushings / Resistance to UV light, etc.

Type test for each type of protection (IEC 60079 series & ISO 80079-37)
Spark ignition test / Determination of explosion pressure (reference pressure) / Overpressure test / Test for non-transmission of an internal ignition / Cable pull test / Purging test / Dilution test / Functional test, etc.

Affected product

Products used or installed at sites such as mines, plants, ships, manufacturing processes, etc. where the atmosphere of explosive gases and dust can be formed.

Industry sector

Explosive Atmospheres
