67 Fluke products designed to intrinsic safety standards A protection method employed in potentially explosive atmospheres, intrinsically safe devices are designed to be unable to release sufficient energy, by either thermal or electrical means, to cause ignition of flammable material (gas or dust/particulates).

Factory Mutual In the United States, Factory Mutual Research, managed by Factory Mutual (FM) Global, is a non-profit scientific and testing organization that has tested and certified over 40,000 products in the last 165 years. FM Research has set certification guidelines for equipment used in potentially explosive atmospheres. Canadian Standards Association (CSA) Accreditation body for North American regula- tions, based in Toronto, Canada. ATEX The primary intrinsi­ cally safe standard, which has been set in the European Union with the Directive 2014/34/EU (replac- ing the 94/9/EC), and commonly called ATEX 114 (Atmo­sphères Explosibles), French for explosive atmospheres. ETL Accreditation body for North American regulations, NEC-500/ NEC-505.
