ASTM Standards

1.1 This test method covers the determination of magneti-zation coercivity (Hcs) of cemented carbide materials and products using coercive force instrumentation. It is patterned after ISO 3326. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.1 This test method defines a resistance probing test for detecting the presence of foreign matter on Printed Wiring Board (PWB) contacts or fingers that adversely affects electri-cal performance. This test method is defined specifically for such fingers coated with gold. Application of this test method to other types of electrical contacts or to fingers

1.1 This specification covers limits of variation for deter-mining acceptability of the chemical composition of cast or wrought nickel, nickel alloy, and cobalt alloy parts and/or material supplied by a producer. Check analysis limits for elements or for ranges of elements not currently listed herein shall be as specified in the applicable material specification or

1.1 This test method describes equipment and techniques for detecting contact resistance transients yielding resistances greater than a speeified value and lasting for at least a specified minimum duration. 1.2 The minimum durations specifed in this standard are I, 10, and 50 nanoseconds (ns).

1.1 This specification covers the requirements for 34 grades of titanium and titanium alloy seamless pipe intended for general corrosion resisting and elevated temperature service as follows: 1.1.1 Grade 1—UNS R50250. Unalloyed titanium, 1.1.2 Grade 2—UNS R50400. Unalloyed titanium, 1.1.2.1 Grade 2H—UNS R50400. Unalloyed titanium (Grade 2 with 58 ksi (400 MPa) minimum UTS),

1.1 This specification covers the requirements for 34 grades of titanium and titanium alloy seamless pipe intended for general corrosion resisting and elevated temperature service as follows: 1.1.1 Grade 1—UNS R50250. Unalloyed titanium, 1.1.2 Grade 2—UNS R50400. Unalloyed titanium, 1.1.2.1 Grade 2H—UNS R50400. Unalloyed titanium (Grade 2 with 58 ksi (400 MPa) minimum UTS),

1.1 This test method describes a procedure to determine the presence of residual stresses in wrought copper alloy products that may lead to stress corrosion cracking. An ammonia vapor atmosphere is used as an accelerated test. 1.2 This test method is only suitable for products fabricated from copper alloys that are known to be susceptible

1.1 This specification a covers the requirements for automated, controlled shot peening of metallic articles prior to electrolytic or aulocatalytic deposition of nickel or chromium,or as a final finish, using shot made of cast steel, conditioned cut wire, or ceramic media. The process is applicable to those materials on which test work has shown it

1.1 This guide covers procedures for reducing the suscep-tibility in some steels to hydrogen embrittlement or degrada-tion that may arise in the finishing processes. 1.2 The heat treatment procedures established herein may be effective for reducing susceptibility to hydrogen embrittle-ment. This heat-treatment procedure shall be used after plating operations but prior to any secondary conversion

1.1 This specification covers the requirements for elecrode-posited zine cobalt alloy coatings on metals. 1.2 The following precautionary caveat pertains to the test method portion only, Section 8, of this specification: This standard does nor purport 10 address all of the safery concerms, if any. associated with is use. I is the respousibility of the
