Explosion proof certification: Explosion proof certification is the process of determining whether equipment meets the requirements of explosion-proof standards, conducting type tests and routine tests for adaptation, and issuing relevant certificates of conformity.
Explosion proof certificate: a document used to determine whether the equipment meets the requirements of the standard, undergoes type testing, and adapts to routine testing. The certificate can be for Ex devices or Ex components.
The full name of 3C certification is "China Compulsory Certification", abbreviated as CCC in English. It is a product implemented by the Chinese government in accordance with laws and regulations to protect consumer personal safety and national security, strengthen product quality managementProduct qualification assessment system. Explosion proof 3C certification refers to the 3C certification of explosion-proof products.
From the above concepts, explosion-proof certification is a work and process,Explosion proof certificateIt is the result document after explosion-proof certification. Explosion proof 3C certification is also a certification process, and the final certificate issued is the CCC certificate.
What customers often say to doExplosion proof certificationWe first need to confirm what product it is, as this involves obtaining an explosion-proof certificate or an explosion-proof 3C certification.
Explosion proof products are divided into explosion-proof electrical products and non electrical products. The products certified with explosion-proof 3C certification are limited to explosion-proof electrical products and do not involve non electrical products or combination products.
What is the difference between explosion-proof certificate and explosion-proof 3C certification?
1. Different product ranges
Both explosion-proof certificate and explosion-proof CCC certification are certification requirements for explosion-proof equipment. Whether to apply for explosion-proof certificate or explosion-proof CCC certification mainly depends on the product category. Simply put, it depends on whether your product is included in the explosion-proof CCC certification product catalog. If so, you need to doExplosion proof CCC certificationNo, just get an explosion-proof certificate.
2. Different authentication methods
The explosion-proof certificate adopts a type test certification mode, while the explosion-proof CCC certification adopts a combination of type test factory review. Simply put, to apply for an explosion-proof certificate, only samples need to be sent for testing. Once the testing is qualified, the certificate can be issued; Applying for explosion-proof CCC certification not only requires product testing to be qualified, but also requires a production quality system audit of the product manufacturing factory (commonly known as factory audit). For applying enterprises, obtaining explosion-proof CCC certification requires having a production factory, whether it is a self owned factory or an OEM/ODM factory.
3. Different certification bodies
It is worth noting that some institutions are both testing laboratories and issuing agencies for explosion-proof certification, as well as issuing agencies or laboratories for explosion-proof 3C certification.
4. The product certification standards for explosion-proof certificate and explosion-proof 3C certification are the same, both in accordance with the GB/T3836 series standards.
