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 themselves. The process is relatively long, the overall cost is high, and it is time-consuming and labor-intensive.

Proxy application:

Proxy application refers to the entire process of proxy application directed to Shenzhen Zhongnuo Testing Technology Co., Ltd., including data modification, prototype debugging, and progress coordination, which are entrusted to the proxy agency to ensure good progress. The general processing cycle is 1-2 months, and the comprehensive cost is controllable, saving time and effort.



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

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

Both parties have reached a cooperation agreement to apply for product certification materials, including product electrical schematics, assembly drawings, structural drawings, 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 quantity of samples varies for different product categories.

Upon passing the test, 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.
