These specifications provides the manufacture and testing, as well as individual design, electrical, mechanical, and workmanship requirements for a system of flexible insulated temporary bypass jumpers used on energized power lines and equipment. These specifications for a system of bypass jumpers are covered in four parts as follows: clamps for bypass jumpers; ferrules for bypass jumpers; cable for bypass jumpers; and bypass jumpers (complete assembly with clamps, ferrules, and cable). The use and maintenance of these equipments are not addressed in these specifications.
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 manufacture and testing of flexible insulated temporary bypass jumpers (bypass jumpers) used on energized power lines and equipment.
1.2 It is common practice for the user of this protective equipment to prepare complete instructions and safety regulations to govern in detail the correct and safe use of such equipment. Also see 4.2.
1.3 The use and maintenance of this equipment are beyond the scope of these specifications.
1.4 These specifications for a system of bypass jumpers is covered in four parts as follows:
Clamps for Bypass Jumpers
5 – 17
Ferrules for Bypass Jumpers
18 – 31
Cable for Bypass Jumpers
32 – 40
Bypass Jumpers (complete assembly
41 – 55
1.5 Each of the four parts is an entity of itself, but is listed as a part of the system for completeness and clarification.
1.6 The values stated in SI units are to be regarded as the standard. See ASTM IEEE/ASTM SI 10.
1.7 The following precautionary caveat pertains only to the test method portions, Sections 13, 26, 48, and 55 of these specifications. 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.
