What should be noted when applying for a domestic explosion-proof certificate for products? Zhongnuo Testing has summarized years of experience in the explosion-proof certification industry, mainly sharing the following points:

(1) Is the product design designed in accordance with the relevant standards of GB/T3836. For example, for explosion-proof devices, reference should be made to GB/T 3836.1 and GB/T 3836.2, while for intrinsically safe devices, reference should be made to GB/T 3836.1 and GB/T 3836.4.

(2) Can complete certification materials be provided, such as schematic diagrams, assembly drawings, structural diagrams, BOM tables, manuals, enterprise standards, etc. Some products may also require battery testing reports, wireless transmission power reports, sealing processes, and shell material reports.

(3) Are there clear requirements for the issuing authority and explosion-proof level. Sometimes it is the end customer who requests explosion-proof certification, which requires understanding the type of explosion-proof environment and area in which the end customer's product is used, and whether there are specific requirements for the product's IP, anti-corrosion level, and certification authority.

(4) Is it for the company to collect evidence themselves or for an agent to collect evidence. If the enterprise is not familiar with explosion-proof design standards, certification process, drawing preparation, etc., and is doing explosion-proof certification for the first time, it is recommended to choose Zhongnuo Testing for certification, which saves time, effort, and worry.

(5) Finally, there is the cost budget. If you choose Zhongnuo Testing for evidence collection, you will need to pay for technical service fees. Zhongnuo Testing will save manpower and material resources for enterprises, shorten the certification cycle, and contribute our efforts to the launch of explosion-proof new products for enterprise friends
