Abstract
This specification establishes the requirements brass plates, sheets, strips, and rolled bars made from UNS C21000, C22000, C22600, C23000, C24000, C26000, C26800, C27200, or C28000. Plates are generally available only in the hot-rolled temper. The standard tempers of as hot rolled, rolled, annealed, and annealed-to-temper materials are detailed in this specification as well as in other specifications listed herein. This specification also contains information on the required tensile strengths, Rockwell hardness and grain sizes of the materials. The Rockwell hardness test can be used to test for general conformity to the specification requirements for temper, tensile strength and grain size.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

1.2 Units—The values stated in either inch-pound units or SI units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
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.
