Abstract :
Factory Mutual began testing and approval of intrinsically safe equipment in 1964. Approval requirements were developed using the Instrument Society of America Recommended Practice RP12.2 and data from European test agencies having extensive background in this subject. Since 1964, many instrument manufacturers have received Factory Mutual approval. Listings of approved equipment are published in the Factory Mutual Approval Guide.
