Certificate:

The exploder got the MA mark and Explosion-proof Certificate issued by CQST. (CQST is mutual recognition with Norway’s NEMKO, Germany’s PTB, America’s UL\FM, Australian’s TESTSAFE, France’s LCIE\INERIS, Britain’s BASEEFA, Russia’s CCVE, Netherlands’s KEMA, Japan’s TIIS and so on.)

Remarks:

Exploder should kept by the hand, regular three-month overhaul, and the exclusion of internal tide, the establishment of maintenance records. The overhaul of the Exploder, the main performance indicators must be qualified, or not use.
