This standard shall apply to the repair of communication equipment certified under the following categories:

a. Intrinsically safe for Class 1, 11 or 111, Division 1, Groups A, B, C, D, E, F and G, and/or

b. Nonincendive for Class 1, Division 2, Groups A, B, C and D, and/or c. Suitable for Class 11, Division 2, Groups F and G, and/or, d. Suitable for Class 111, Division 1 and 2.

This standard is intended to be used in conjunction with repair of communication equipment.

This standard does not apply:

• when modifications are made to the equipment;

• when a certification label is applied to equipment not shipped from the original manufacturer as certified;

• to repairs made by facilities owned by the original manufacturer.

The manufacturer's repair facilities are covered by the certification agreement for the listed product. That agreement requires the manufacturer to provide adequate facilities for repair of the listed product.

Items not considered as repairs are those in which an action is performed on a unit which does not require the outer casing of the unit to be opened in a manner which exposes the internal electrical circuits of the unit. The following is a partial list of examples which are not considered to be repairs:

• replacement of an antenna,

• changing an external accessory,

• changing/replacement of a battery pack,

• software loaded into the unit,

• a control knob,

• escutcheon, or,

• belt clip.

Purpose

This standard serves as the basis for certification of independently owned facilities that repair certified communication equipment for hazardous (classified) locations.
