Annotation of standard text ASTM B122/B122M-20 :
This specification establishes the requirements for copper-nickel-tin, copper-nickel-zinc, and copper-nickel alloy plates, sheets, strips, and rolled bars made from UNS C70600, C70620, C71000, C71500, C71520, C72200, C72500, C73500, C74000, C74500, C75200, C76200, or C77000 alloy. Each product should be manufactured by hot or cold working, and annealed if required, to produce a uniform wrought structure that meets the specified temper properties. This specification also contains information on the standard tempers for and tensile strengths of hot-rolled, cold-rolled, and annealed tempers. In case of disagreements, the chemical composition is determined following appropriate methods listed here. Grain size is the standard requirement for all products in the annealed tempers.

1.2 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 1.3 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. |
