Anotácia textu normy ASTM B100-20 :
This specification covers the standard for wrought copper-alloy bearing plate and bearing sheets intended for use in bridges and other structures. The plates and sheets are also proposed for use as fixed or expansion bearings where motion is slow and intermittent. Specimens shall be manufactured by hot working, cold working, and annealing. Specimens shall adhere to mechanical properties such as tensile strength, yield strength, and elongation. The plates and sheets shall be subjected to tensile, hardness, and compression tests. The specimens shall also undergo chemical analysis. When the specimens fail to conform to the specification, a retest shall be permitted.

1.1 This specification establishes the requirements for wrought copper-alloy bearing plate and bearing sheets for application in bridges and other structures. Specifically, the plates and sheets are to be used for fixed or expansion bearings where the motion is slow and intermittent with pressures not exceeding 3 ksi (20 MPa). 1.2 Units—The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.2.1 Exception—Values given in inch-pound units are the standard except for grain size, which is stated in SI units. 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. |
