ISA submits electrical safety standard to ANSI

Research Triangle Park, NC (17 April 2007) - ISA has submitted ISA-12.12.01, "Nonincendive Electrical Equipment for Use in Class I and II, Division 2 and Class III, Divisions 1 and 2 Hazardous (Classified) Locations" for ANSI approval.

The purpose of this standard is to provide minimum requirements for the design, construction, and marking of electrical equipment or parts of such equipment for use in Class I and Class II, Division 2 and Class III, Divisions 1 and 2 hazardous (classified) locations.

The equipment, in normal operation and under the conditions prescribed in the standard, is not capable of causing ignition of the surrounding atmosphere. However, the equipment may contain electronic components that operate at incendive levels and may also have field wiring that is incendive.

The standard will serve to establish uniformity in test methods for determining the suitability of the equipment and associated circuits and components as they relate to potential ignition of a specific flammable gas or vapor-in-air mixture, combustible dust, easily ignitable fibers, or flyings.

The committee that produced the standard works to formulate standards, recommended practices, and technical reports for safe and practical use of electrical equipment in hazardous (classified) locations, and standards for equipment used to detect, alarm, or process signals relating to the detection of materials within their combustible ranges, and to promote their use.
