How does a company apply for the Explosion-proof CCC Certification?
1. Self-Application: Companies apply to certification bodies independently, prepare relevant documents on their own, assist in debugging prototypes, and modify any non-standard parts in the documents. This process is relatively time-consuming with a higher overall cost, requiring both time and effort.
2. Agent Application: The application process involves a specialized explosion-proof electrical equipment consulting service agency (such as Shenzhen ZhongNuo Testing Technology Co., Ltd.) handling the entire consultation and application, including material revisions, prototype debugging, and progress coordination. The progress is well-guaranteed. Fast certification, manageable overall costs, time and labor-saving.

What standards are used for explosion-proof certification? What are the technical requirements?
An explosion-proof type is a type of explosion-proof design for electrical equipment.
The housing is designed to withstand explosive mixtures entering through the housing joint surfaces or structural gaps, allowing for internal explosions without damage.
And 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 properties. 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 the explosion-proof triad differ according to the different explosive gas environments of 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.
