ASTM F2321-05

Standard Specification for Flexible 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 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 .
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:TitleSectionsClamps for Bypass JumpersFerrules for Bypass JumpersCable for Bypass JumpersBypass Jumpers (complete assemblywith clamps, ferrules, and cable)
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 SI 10.
The following precautionary caveat pertains only to the test method portions, Sections , , , and 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.
