Progress in hazardous location approvals is being driven both by improvements in the certification standards and by marketplace demand. More and more, hazardous location approvals are becoming inextricably linked to performance certification. We are familiar with many of the most important performance standards currently mandated by leading approvals agencies.

Below is a partial list of of the performance standards we are familiar with:

Harmonized standards IEC 60079-29-1: Performance requirements of detectors for flammable gases
IEC 60079-29-4: Performance requirements of open path detectors for flammable gases
CSA C22.2 No. 152-M1984: Combustible Gas Detection

ANSI & ISA ANSI/ISA 12.13.01: Performance Requirements for Combustible Gas Detectors
ANSI/ISA-RP12.13.02: Recommended Practice for the Installation, Operation, and Maintenance of Combustible Gas Detection Instruments
ANSI/ISA 12.13.04: Performance Requirements for Open Path Combustible Gas Detectors
ISA 92.0.01: Performance Requirements for Toxic Gas-Detection Instruments: Hydrogen Sulfide
ISA 92.00.01: Performance Requirements for Toxic Gas Detectors
ISA 92.00.04: Performance Requirements for Open Path Toxic Gas Detectors
ISA 92.03.01: Performance Requirements for Ammonia Detection Instruments (25-500 ppm)

FM FM 3260: Radiant Energy-Sensing Fire Detectors
FM 6325: Combustible Open Path Gas Monitors
FM 6310/6320: Combustible Gas Detectors

European Union (EU) EN 45544: Electrical apparatus used for the direct detection and direct concentration measurement of toxic gases and vapours
EN 50271: Electrical apparatus for the detection and measurement of combustible gases, toxic gases or oxygen
EN 61207-1: Tunable semiconductor laser gas analyzers
EN 61779-1: General requirements and test methods
EN 61779-2: Selection, installation, use and maintenance of detectors for flammable gases and oxygen
EN 61779-3: Requirements for functional safety of fixed gas detection systems
EN 61779-4: Performance requirements for group II apparatus indicating a volume fraction up to 100% lower explosive limit
