C14200 DPA Phosphorized arsenical

C19200 Phosphorized, 1 % iron

C23000 Red Brass

C44300 Admiralty Metal Types B,

C44400 C, and C44550 D

C60800 Aluminum Bronze

C68700 Aluminum Brass Type B

C70400 95-5 Copper-Nickel

C70600 90-10 Copper-Nickel

C70620 90-10 Copper-Nickel (Modified for Welding)

C71520 70-30 Copper-Nickel (Modified for Welding)

C72200 Copper-Nickel

1.4 Units—The values stated in either in-pound units or SI units are to be regarded separately as the standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems could result in nonconformance with the specification.

1.5 Product produced in accordance with the Supplementary Requirements section for military applications shall be produced only to the inch-pound system of this specification.

1.6 The following safety hazard caveat pertains only to the test methods described in this specification. This standard does not purport to address all of the safety concerns, if any,

associated with its use. It is the responsibility ofthe user of this standard to establish appropriate safety and health practices and determine the applicability ofregulatory limitations prior to use. Some specific hazards statements are given in Sections 1, 12 and 18.

1.7 (Warning—Mercury has been designated by many regulatory agencies as a hazardous material that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury containing products. See the applicable product Safety Data Sheet (SDS) for additional information. Users should be aware that selling mercury and/or mercury containing products into your state or country may be prohibited by law.)
