This specification covers the in-service inspection and electrical testing of temporary protective grounding jumper assemblies used by electrical workers in the field on de-energized electric power lines, circuits, and equipment. These assemblies consist of flexible cables, ferrules, clamps, and connectors. The test procedures detailed here provide an objective means of determining if a grounding jumper assembly meets minimum electrical specifications. The application, care, use, and maintenance of this equipment are not addressed in this specification.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
1.1 These specifications cover the in-service inspection and electrical testing of temporary protective grounding jumper assemblies which have been used by electrical workers in the field.
1.2 These specifications discuss methods for testing grounding jumper assemblies, which consist of the flexible cables, ferrules, clamps and connectors used in the temporary protective grounding of de-energized circuits.
1.3 Manufacturing specifications for these grounding jumper assemblies are in Specifications .
1.4 The application, care, use, and maintenance of this equipment are beyond the scope of this specification.
1.5 Units of measurement used in this specification are in the Metric system (SI) with English units given in parentheses.
1.6 The following safety hazards caveat pertains only to the test portions of 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 requirements prior to use.
