防爆认证的费用是多少

Explosion-proof grade testing necessitates engagement with a national certification agency, and the costs vary based on the product, with experimental review fees typically ranging from 10,000 to 20,000.

The certification process generally requires submitting product design drawings, product manuals, and company standards to the national certification agency. However, the agency conducts only the necessary experiments and reviews your data (which involves a fee), and does not provide detailed feedback. This means you’ll receive only a pass/fail determination without a structured explanation or guidance on potential modifications.
