Can coal safety certification be converted to explosion-proof 3C certification? - Answer from Shenzhen ZhongNuo Testing Technology Co., Ltd.
Based on the announcement, as of October 1, 2020, certain explosion-proof electrical equipment has been added to the mandatory product certification list.
It is the CCC certification. Products under the explosion-proof 3C certification category obtain the explosion-proof CCC certification by undergoing a "type test + factory audit" certification process.
Coal Mine Safety Certification, abbreviated as "煤安认证," is a mandatory certification implemented by the Safety Standardization Center for all types of products and equipment used underground in coal mines.
The certification method combines "type testing" with "factory audit."
Currently, mandatory product certification bodies and coal safety certification bodies are under different departments, with no mutual recognition between them.
Coal safety certification and explosion-proof 3C certification are independent of each other.
The coal safety certification or the explosion-proof 3C certification cannot be substituted or converted for each other; they must be applied for separately.

Sample requirements for applying for the防爆CCC certification:
The sample machines submitted by the company for inspection must match the approved drawings and be fully assembled. The number of units inspected should meet the requirements.
If special disassembly tools are required, they should be sent along as well.
For encapsulated electrical equipment, a set of both encapsulated and non-encapsulated products should be submitted.
The transparent parts for the observation window should be supplied separately with at least 3, but no more than 5 pieces.
Translucent parts for lighting fixtures should be supplied separately in at least 5 pieces, with a total of 8.
Provide 3 to 5 pieces of 35156 rubber blocks for the rubber aging test.
Two plastic sheets with a diameter of 15060mm are required for the insulation resistance test of the plastic housing. If the size permits, the test can be directly conducted on the plastic housing.
Finished products typically require 1-2 samples.

What is the relationship between the explosion-proof certificate and the explosion-proof CCC certification?
Which certifications are required for a company's explosion-proof products to enter the market? What are the requirements for the applying company, etc.? These are many of the current confusions faced by enterprises.
Below, ZN Testing will explain in plain language for everyone's clarification.
Firstly, both explosion-proof certificates and explosion-proof CCC certifications are certification requirements for explosion-proof equipment.
Whether to apply for the explosion-proof certification or the explosion-proof CCC certification mainly depends on the product category.
Put simply, it's about checking whether your product is listed in the防爆CCC certification product catalog.
Yes, it requires the explosion-proof CCC certification; no, just the explosion-proof compliance certificate.

Do you have a product catalog for explosion-proof electrical equipment that has been converted to mandatory product certification (CCC certification)?
ZhongNuo Inspection: Yes. The market has transitioned from production license to mandatory product certification for explosion-proof electrical equipment at the same time as its release.
We also issued a notice regarding the conversion of explosion-proof electrical products from production license to mandatory certification scope.
Products within the product catalog must be produced, sold, or engaged in other business activities during the transitional period with a valid production license or CCC certification.
After the transitional period, only products with valid CCC certification can be manufactured, sold, or used in other business operations.
