Currently, the applicable standards for explosion-proof certification and explosion-proof 3C certification in China are primarily the GB/T3836 series. This series covers various types of explosion-proofing, each with specific requirements. Below are the main parts of the GB/T3836 series and their corresponding types of explosion-proofing:
GB/T 3836.1-2021: Explosive Atmospheres - Part 1: Equipment - General Requirements. This is the fundamental standard that all explosion-proof equipment must comply with.
GB/T 3836.2-2021: Explosive Atmospheres – Part 2: Equipment protected by a "d" type flameproof enclosure. This specifies the requirements for equipment protected by flameproof enclosures.
GB/T 3836.3-2021: Explosive Atmospheres – Part 3: Equipment protected by increased safety “e”. This standard specifies requirements for equipment utilizing increased safety protection.
GB/T 3836.4-2021: Explosive Atmospheres - Part 4: Equipment protected by intrinsic safety "i". This standard specifies requirements for equipment utilizing intrinsic safety protection.
GB/T 3836.5-2021: Part 5 of Explosive Atmospheres – Equipment protected by positive pressure enclosures “p”. This specifies the requirements for equipment protected using positive pressure enclosures.
Additionally, there are other standards such as GB/T 3836.6-2017 (equipment with "o" protection for immersion type), GB/T 3836.7-2017 (equipment with "q" protection for sand-filled type), GB/T 3836.8-2021 (equipment with "n" protection type), GB/T 3836.9-2021 (equipment with "m" protection for potting type), and GB/T 3836.31-2021 (dust ignition-proof enclosures with "t" protection), each corresponding to different explosion-proof types and specific protection requirements.
