23 Year Industrial Explosion-Proof Manufacturer

Is Explosion-Proof Certification Mandatory

In China, explosion-proof certification adheres to the GB3836 electrical explosion-proof standard and is mandatory. The certification remains valid for 5 years.

Internationally, explosion-proof certifications entail a one-time accreditation that is valid indefinitely. However, they necessitate annual on-site reviews by engineers from the certifying body, accompanied by an annual fee.
