Key Considerations When Selecting Explosion-Proof Products:

1. Explosion-Proof Certification and Standard Compliance
International Certification
Must obtain mandatory certification for the region of use (e.g., China CNEx/PCEC, EU ATEX, China IECEx).
Confirm that the explosion-proof markings are complete (e.g., Ex db IIB T4 Gb).
Standard Compatibility
Gas environments must comply with GB3836/IEC 60079 series. Dust environments must comply with GB12476/IEC 61241 Series

II. Environmental Compatibility Selection
Hazardous Area Classification
Zone 0/Zone 1/Zone 2 (Gas)
Zone 20/Zone 21/Zone 22 (Dust)
Select the corresponding explosion-proof type based on the zone level (e.g., Zone 0 requires intrinsic safety type ia)
Special Environmental Requirements
Chemically corrosive environments: Select a 316 stainless steel housing
Marine environments: Must pass a salt spray test (1000 hours or longer)
High-temperature locations: Select an appropriate temperature level within groups T1-T6

III. Technical Performance Parameters
Core Protection Indicators
Protection level ≥ IP65 (IP66 recommended for outdoor use)
Shock resistance ≥ 7J (heavy industrial locations)
Surface temperature ≤ 80% of the auto-ignition point of the material in the area
Electrical Parameters
Voltage fluctuation range (±20%)
Protection type (Flameproof type d/Increased safety type e/Intrinsic safety type) i, etc.)
Cable entry type (armored/anti-pullout)

IV. Product Reliability Assessment
Manufacturer Qualifications
Possess an explosion-proof product production license
Provide a complete type test report
Record of successful application in the same industry for at least 3 years
Quality Assurance
Key components (such as transparent components) must pass pressure and weathering tests
Provide MTBF (mean time between failure) data
Warranty period ≥ 3 years (including explosion-proof structural integrity)

V. Lifecycle Management
Installation and Maintenance Requirements
Must be installed by a qualified explosion-proof electrician
Regularly inspect the gap between explosion-proof joints (≤ 0.15mm)
Establish a dedicated maintenance file
Eliminate the use of explosion-proof structures that have been officially eliminated by the state
Mandatory testing is required upon reaching the design life (usually 8-10 years)
Re-certification is required after a major incident
