AbstractThese specifications cover the equipment making up the temporary grounding system used on de-energized electric power lines, electric supply stations, and equipment. These specifications for a system of protective grounding utilizing copper cables are covered in four parts, as follows: clamps, ferrules, cables, and temporary protective grounds. Each of the four parts is an entity of itself, but is listed as a part of the system for completeness and clarification. The clamps shall be subject to design tests for determining mechanical torque strength and electrical short circuit capacity. The ferrules shall be tested for electrical short-circuit capacity and continuous current rating. The elastomer or thermoplastic making up the jacket of the flexible cable shall be tested according to the specified methods.1.1 These specifications cover the equipment making up the temporary grounding system used on de-energized electric power lines, electric supply stations, and equipment.1.2 It is common practice for the users of protective grounding equipment to prepare complete instructions and regulations to govern in detail the correct use and maintenance of such equipment.1.3 The uses and maintenance of this equipment are beyond the scope of these specifications.1.4 These specifications for a system of protective grounding utilizing copper cables are covered in four parts, as follows:         SectionsClamps for Temporary Protective Grounds   4 – 16Ferrules for Temporary Protective Grounds   17 – 30Cables for Temporary Protective Grounds   31 – 39Protective Grounds (Complete Assembly With Clamps, Ferrules,   and Cable)   40 – 521.5 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 Currents presented in Table 1 are based upon cable melting times, as determined from equations by I.

5.1 Significance—With the birth of minimally invasive surgery in the 1960s, there has been a requirement for guide wires. The guide wires serve as the access line by which procedures like balloon angioplasty and stent placement are conducted. A guide wire typically consists of a mandrel, coil and in some cases a safety wire is used. The market for guide wires continues to grow as the number of procedures increases. For successful manufacturing of guide wires, linearity or straightness of 304 stainless steel and nitinol wire that is used for the manufacture of guide wire mandrels is critical to their end use performance. Users of guide wires require that they must navigate a tortuous anatomy.5.1.1 A second part of minimally invasive surgery is the use of machined or formed wire, tube, or rod. In this case, straightness of rod, tube, and wire that is going to be machined or subjected to a forming practice such as bending needs to be very linear or straight so it is accurately fed into the equipment that is used for the machining or forming practice. Laser machining is an example of a machining operation that requires a wobble-free piece of rod, tubing, or wire so that it can be properly fed into the alignment bushings of the laser. Wire forming equipment also requires wobble-free material for the same reason.5.2 Use—These test methods can be used by users and producers of medical grade bar, rod, tubing, and wire to specify requirements to evaluate and confirm the straightness of material. Depending upon the type of material and its metallurgical condition, it may be possible to reprocess the material to reduce its non-linearity.1.1 This standard covers the various test methods to be used for measurement of straightness of bar, rod, tubing, and wire. These test methods apply primarily to bar, rod, tubing, and wire that are ordered in the straightened and cut-to-length condition. They also apply to small diameter tubing and wire that has been specially processed to roll off a spool in the straightened condition.1.2 These test methods apply to straightness of round wire that has a diameter between 0.05 and 4.78 mm (0.002 and 0.188 in.). They also apply to flatness (camber) of flat-shaped wire or ribbon with a maximum dimension between 0.05 and 4.78 mm (0.002 and 0.188 in.). For flatness (camber) measurement, refer to Test Method F2754/F2754M.NOTE 1: The current version of Test Method F2754/F2754M covers a different diameter range (0.0127 to 4.78 mm (0.0005 to 0.188 in.)) and does not include superelastic NiTi. These exceptions would not affect the camber measurement as conducted by Test Method F2754/F2754M.1.3 These test methods apply to straightness of round tubing that has an outer diameter between 0.05 and 6.35 mm (0.002 and 0.25 in.).1.4 These test methods apply to straightness of round rod that has a diameter between 4.78 and 6.35 mm (0.188 and 0.25 in). It also applies to flatness (camber) of flat and shaped rod with a maximum dimension between 4.78 and 6.35 mm (0.188 and 0.25 in). For measurement of flatness (camber), refer to Test Method F2754/F2754M.NOTE 2: The current version of Test Method F2754/F2754M covers a different diameter range (0.0127 to 4.78 mm (0.0005 to 0.188 in.)) and does not include superelastic NiTi. These exceptions would not affect the camber measurement as conducted by Test Method F2754/F2754M.1.5 These test methods apply to straightness of round bar that has a diameter between 6.35 and 101.6 mm (0.25 and 4 in). It also applies to flatness (camber) of flat and shaped bar with a maximum dimension between 6.35 and 101.6 mm (0.25 and 4 in). For measurement of flatness (camber), refer to Test Method F2754/F2754M.NOTE 3: The current version of Test Method F2754/F2754M covers a different diameter range (0.0127 to 4.78 mm (0.0005 to 0.188 in.)) and does not include superelastic NiTi. These exceptions would not affect the camber measurement as conducted by Test Method F2754/F2754M.1.6 These test methods apply to ferrous and non-ferrous alloys including linear-elastic or superelastic nitinol. Refer to Terminology F2005 for more details on NiTi terminology.1.7 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.1.8 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.1.9 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.
