First of all, it is necessary to distinguish whether the product needs to undergo certification or whether explosion-proof electrical testing is required in on-site locations.

On site explosion-proof electrical testing is carried out in accordance with the AO3009-2007 specification for electrical equipment in use, with regular testing conducted at least once every 3 years and a testing report issued. This is mainly aimed at the users of explosion-proof equipment.

Product testing certification generally refers to the process of conducting relevant tests on newly launched products in accordance with the requirements of GB/T 3836 series standards and obtaining explosion-proof certificates. This requires the provision of product design drawings, manuals, and other materials, usually targeting the manufacturer or supplier of the equipment.
