Standard Specification for Insulation Resistance Monitor for Shipboard Electrical Motors and Generators

SCOPE
1.1 This specification covers monitoring devices (monitors) for the automatic detection and signaling of low insulation resistance values in idle electrical motors or generators, or both.
1.2 Monitors are intended for permanent installation in both existing or new panels and controller enclosures designed for marine application.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 The following safety hazards caveat pertains only to the test method described in this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
