1.1 These peifications cover the equipment making up the temporary grounding system used on de-energized eletric power lines, electrie supply stations, and equipmen. 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.

1.1 This specification establishes allowable limits for the various types of surface discontinuities that may occur during the manufacture and processing of bolts, screws, studs, and rivets including heat-treated machine screws, tapping screws, and sems (the washers of screw-washer assemblies are ex-cluded). This specification covers metric series products with nominal diameters of 4 mm and

1.1 This specification describes the physical, chemical, and mechanical performance requirements for polytetrafluoroeth-ylene (PTFE) pre-fabricated by compression molding or extru-sion into sheet, tube, and rod shapes which may be used for implant products. 1.2 PTFE is a high molecular weight straight chain member of the generic class of perfluorocarbon (containing only the elements fluorine and

1.1 This practice covers a procedure by which the irritancy of a material may be assessed through contact with abraded and intact skin of rabbits. 1.2 The results of this practice depend upon the effective-ness with which contact between the skin and the test material is established and maintained. Because of the operator tech- nique

1.1 This specification covers polyethylene (PE) pipe made in dimensions based on outside diameters of90 mm (3.500 in.) and larger. 1.2 Three standard outside diameter sizing systems are detailed: one known as the ISO metric system, one known as the IPS system, and the other known as the DIPS system. See 5.2.5 for guidelines for

1.1 This specification covers insulating rods and foam-filled tubes made from fiberglass-reinforced plastic (FRP) that are intended for use in live line tools. 1.2 This specification does not include insulating foam-filled tubes and rods from other materials. Specifications for fittings and attachments to rods and foam-filled tubes for complete tools are not covered in this

1.1 This practice provides a procedure for comparing the sizes ofnonspherical particles in a test sample determined with different types ofautomatic particle counters, which operate on different measuring principles. 1.2 A scale factor is obtained by which, in the examination of a given powder, the size scale of one instrument may be multiplied to agree

1.1 This specification covers the material requirements for high-purity, dense aluminum oxide for load-bearing surgical implant applications. 1.2 This specification does not cover finished parts (for example, femoral heads, acetabular inserts, dental implants and the like). It is intended as a qualification of the material as delivered to the parts manufacturer.

1.1 This specification covers the requirements for single wall and coextruded cellular core smooth-wall poly(vinylchloride) conduit and fittings for underground communication and electrical power wire and cables. Plastics which does not meet the material requirements specified in Section 5 is excluded from single layer and all coextruded layers. 1.2 The values given in parentheses are

1.1 This specification covers the in-service care, inspection,testing, and use voltage of insulating blankets for protection of workers from accidental contact with live electrical conductors, apparatus, or circuits. The product requirements and acceptance testing are as shown in Specification D1048. 1.2 The values stated in inch-pound units are to be regarded as standard. The values
