CCC for electrical explosion-proof products in China

20. May 2021

New CCC regulations for certain electrical explosion-proof products have come into force in China last year on 1 October 2020. The announcement came after a transition period of 1 year, which allowed companies to undertake respective change management to comply to the new requirements.



Among others, the list of new product categories that require CCC includes:

• Electric motors

• Pumps

• Switches, control and starter products

• Actuators and solenoid valves

• Surveillance and communication products (e.g. cameras or loudspeakers)

• Cable glands, junction boxes, connectors

• Refrigeration and air conditioning units, dehumidifiers

• Sensors (e.g. temperature sensor, speed sensor, position sensor)

• Safety barriers

Some of the products need regular CCC certification in addition to the CCC ex certification, f.e. electrical motors.

Each accredited Chinese authority releases their own implementation rules, which describe the process of testing, auditing, classification, etc.

These rules tend to differ from another, but all are fundamentally defined by the regulations given out by the CNCA. The certification process is supposed to guarantee the conformity of products according to the national GB standards, which define the methods and specifications.

Here a list of the relevant standards:

No. Explosion-proofing type GB standards

2 Increased safety “e” GB3836.3

5 Immersion “o” GB/T3836.6
