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

1.1 This specification covers chlorinated poly(vinyl chlo-ride) (CPVC) pipe made in standard thermoplastic pipe dimen-sion ratios and pressure rated for water (see Appendix).Included are criteria for classifying CPVC plastic pipe mate-rials and CPVC plastic pipe, and requirements and test meth-ods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality.Methods of marking are

1.1 This specification covers chlorinated poly(vinyl chlo-ride) (CPVC) threaded Schedule 80 pipe fittings. Included are requirements for materials, workmanship, dimensions, and burst pressure. NOTE 1—The CPVC fittings covered by this specification were covered previously in Specification D2464.

1.1 This practice describes procedures for taking a sample of cryogenic aerospace fluid for analysis. 1.2 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 appro-priate safety, health, and environmental practices and deter-mine the

1.1 This test method covers the analysis ofstress in glass by means of a polarimeter based on the principles developed by Jessop and Friedel (1, 2). 2 Stress is evaluated as a function of optical retardation, that is expressed as the angle of rotation of an analyzing polarizer that causes extinction in the glass. 1.2

1.1 This specification covers the chemical, mechanical, and metallurgical requirements for cobalt-28 chromium-6 molyb-denum alloy unfinished investment product castings for surgi-cal implant applications and casting alloy in the form of shot,bar, or ingots to be used in the manufacture of surgical implants. This specification does not apply to completed surgical implants made from castings.
