Explosive atmospheres - Gas detectors. Selection, installation, use and maintenance of detectors for flammable gases and oxygen subscription-only Distributions of other particle characteristics

Distributions of other particle characteristics are required in addition to particle size distributions (see ISO 9276-1)

BS EN 62132-4 describes a method to measure the immunity of integrated circuits in the presence of conducted radiofrequency disturbances

Explosive atmospheres - Gas detectors. Selection, installation, use and maintenance of detectors for flammable gases and oxygen subscription-only Distributions of other particle characteristics1 Scope This part of IEC 6007929 gives guidance on, and recommended practice for, the selection, installation, safe use and maintenance of electrically operated Group II equipment intended for use in industrial and commercial safety applications and Group I equipment in underground coal mines for the detection and measurement of flammable gases complying with the requirements of IEC 60079291 or IEC 60079294. This standard is applicable for oxygen
