Sample requirements for applying for the explosion-proof CCC certification:
The sample machine submitted by the company must match the approved drawings and be fully assembled. The number of inspections 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 unencapsulated products should be submitted.
The transparent parts for the observation window should be supplied with an additional 5, at least 3 pieces.
The transparent parts of the lighting fixtures should be sent separately in at least 5 pieces, with an additional 8.
Rubber aging tests should provide 3 to 5 pieces of 35156 rubber blocks.
Two 15060mm diameter plastic sheets are required for the insulation resistance measurement of the plastic casing. If the dimensions allow, the measurement can be directly conducted on the plastic casing.
Generally, 1-2 finished products are required.

We typically refer to explosion-proof product certification as the safety certification for explosion-proof products entering the market, also known as explosion-proof certification. The certificate issued is called an Explosion-Proof Certificate of Conformity.
CCC Certification, which stands for "China Compulsory Certification," is abbreviated as CCC.
The CCC certification mark is denoted as "CCC" and is recognized and supervised by the Certification and Supervision Commission according to the "Regulations for Compulsory Product Certification."
Regulation No. 5 of the China Quality Supervision, Inspection and Quarantine Commission for product certification system.

What products can apply for the intrinsically safe explosion-proof certification? What are the requirements?
"An intrinsically safe design is one of the many explosion-proof protection types, which limits electrical energy so that the equipment remains safe even in the event of a fault."
A type of explosion-proof protection where the generated energy is not sufficient to ignite the surrounding explosive environment.
Therefore, intrinsically safe equipment has restrictions on current, voltage, capacitance, inductance, and other electrical parameters, and is only suitable for low-power devices.
Additionally, specific requirements are in place for the power supply method of intrinsic safety equipment, plastic housing, and wireless transmission.
The product application for intrinsic safety certification requires submission of the product's schematics, PCB layouts, and other relevant documents.
ZhongNuo Inspection has dedicated engineers specializing in intrinsically safe circuit and structural design.
We offer technical consulting services for explosion-proof circuit design, drafting, and modifications. We have extensive experience in designing and obtaining certifications for intrinsically safe ia, ib, and ic explosion-proof classifications.
