This standard covers conformance tests and requirements for the coating integrity of carbon steel pole mounted enclosures containing apparatus energized in excess of 600 volts, typically located out of reach of the general public, including, but not limited to the following types of equipment enclosures: a. Pole-mounted distribution transformers; b. Pole-mounted switches; c. Pole-mounted regulators; d. Pole-mounted metering equipment; e. Pole-mounted reclosers; f. Pole-mounted switchgear The purpose of this standard is to describe the requirements of a coating system for pole-mounted equipment enclosures to ensure long field life with minimum maintenance. This standard was originally published by ANSI in 1996 with NEMA as the secretariat. The copyright of this document is now being shared between IEEE and NEMA with IEEE responsible for the maintenance of this standard. This PAR is being submitted for approval so that the C57.12.31 standard can be converted to the IEEE format for publication and future development. New IEEE Standard - Superseded. Conformance tests and requirements for the coating integrity of carbon steel pole mounted enclosures containing apparatus energized in excess of 600 volts, typically located out of reach of the general public, including, but not limited to, the following types of equipment enclosures: polemounted distribution transformers, pole-mounted switches, pole-mounted regulators, pole-mounted metering equipment, pole-mounted reclosers, and pole-mounted switchgear are covered.
