Description / Abstract:

This standard contains the basic requirements for the construction and testing of dust-ignitionproof electrical equipment.

This standard is intended to be used in conjunction with Approval Standard Class 3600 which includes the general requirements that apply to all types of hazardous (classified) location protection methods.

This standard does not apply to equipment rated for use in atmospheres containing pyrophoric substances, or other dusts that do not require oxygen for combustion.

This standard does not take into account the risk of ignition of a dust due to electrostatic causes nor from sparking due to friction or parts striking the equipment enclosure.

Purpose

This standard states Approval requirements for dust-ignitionproof electrical equipment for Class II, Division 1, Groups E, F and G; and Class III, Division 1 hazardous (classified) locations.

Approval criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a surveillance program.
