How to apply for explosion-proof certification for enterprises

● Free application:

Enterprises apply to certification agencies on their own, prepare relevant materials, assist in debugging prototypes, and modify non-standard parts of the materials on their own. The cycle is relatively long, the overall cost is high, and it is time-consuming and laborious.

● Agency application:

The agency application is directed to Shenzhen Zhongnuo Testing Technology Co., Ltd. for the entire process of agency application, including data modification, prototype debugging, and progress coordination, which are handed over to the agency with good progress assurance. The general processing cycle is 1-2 months, with controllable comprehensive costs and time-saving and labor-saving.

The basic process of applying for explosion-proof certification at Shenzhen Zhongnuo Testing Technology Co., Ltd

The applicant submits an application request, and Zhongnuo Testing evaluates a reasonable explosion-proof mark based on the product's usage environment, product structure, and customer requirements, and reports the certification cost, cycle, and required information.

Both parties have reached a cooperation agreement to apply for the recognition and delivery of product materials, including product electrical schematic diagrams, final assembly drawings, structural diagrams, BOM tables, nameplates, product manuals, and enterprise standards. Different explosion-proof types and products provide different information. 

Provide samples to Zhongnuo Testing Laboratory for testing, and the required number of samples varies for different product categories.

If the test is qualified, a test report and explosion-proof certificate will be issued directly. If the test fails, Zhongnuo Testing will assist the applicant in rectifying the product.
