ASTM F2321-14(2020)

Standard Specification for Flexible and Rigid Insulated Temporary By-Pass Jumpers

ABSTRACT
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.
SCOPE
1.1 These specifications cover the manufacture and testing of flexible insulated temporary By-Pass jumpers (By-Pass 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 By-Pass jumpers is covered in four parts as follows:

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 IEEE/ASTM SI 10.  
1.7 The following precautionary caveat pertains only to the test method portions, Sections 13, 26, 48, and 55 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.8 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
