How to Apply for a防爆CCC Certification for a Company?
1. Self-Application: Companies apply directly to the certification body, independently prepare relevant documents, assist in debugging prototypes, and modify any irregularities in the documents. The process is relatively longer, with higher overall costs and requires more time and effort.
2. Agent Application: The application involves the entire consulting and application process by specialized explosion-proof electrical technology consulting service agencies (such as Shenzhen ZhongNuo Inspection & Testing Technology Co., Ltd.), including material modifications, prototype debugging, and progress coordination, which are handled by the consulting agency, ensuring better progress assurance. Quick certificate acquisition, controllable comprehensive costs, time and effort-saving.

What standards are used for explosion-proof certification? What are the technical requirements?
An explosion-proof type is a type of explosion prevention in electrical equipment.
The housing is designed to withstand explosive mixtures entering through the housing joint surfaces or structural gaps, and to withstand internal explosions without damage.
And cause ignition of an explosive gas atmosphere formed by one or more gases or vapors.
The explosion-proof housing must possess both explosion-proof and anti-explosion capabilities. Generally, the outer casings of products designed for explosion-proof purposes are rather bulky.
Products and equipment suitable for fixed installation and use.
Explosion-proof interface width, gap, and roughness are the three key elements of explosion-proof housing design.
Design requirements for explosion-proof three elements vary depending on the different explosive gas environments in mining Class I, non-mining Class IIA, IIB, and IIC.
Refer to the design standards of GB/T3836.1 and GB/T3836.2 for specifics.
Zhenuo Inspection has long been dedicated to explosion-proof product design, testing, and certification services.
We have a team in the explosion-proof field, well-versed in explosion-proof standard requirements.
We offer explosion-proof housing design, drafting, modification guidance, certification agency services.
