This standard covers conformance tests and requirements for the enclosure integrity of pole-mounted equipment containing apparatus energized in excess of 600 V, typically not accessible to the general public, such as but not limited to the following types of equipment: a) Pole-mounted distribution transformers b) Pole-mounted switches c) Pole-mounted regulators d) Pole-mounted metering equipment e) Pole-mounted reclosers/sectionalizers f) Pole-mounted capacitors The purpose of this standard is to describe the requirements for a comprehensive enclosure integrity system for pole-mounted equipment providing long service life with minimum maintenance Revision Standard - Active. Conformance tests and requirements for the coating integrity of carbon steel pole-mounted enclosures containing apparatus energized in excess of 600 V, and not for application in coastal or other severe environments, are specified in this standard. These enclosures are typically located out of reach of the general public, and include, but are not limited to, the following types of equipment enclosures: pole-mounted distribution transformers, pole-mounted switches, pole-mounted regulators, pole-mounted metering equipment, pole-mounted reclosers, and pole-mounted switchgear.
