1.1 本规范涵盖非合金钼和钼合金板、片、带、箔和带，如下所示: 1.1.1 钼360- 非合金真空电弧铸造钼。 1.1.2 钼361- 非合金粉末冶金钼。 1.1.3 钼合金363- 真空电弧铸造钼-0.5 % 钛-0.1 % 锆（TZM）合金。 1.1.4 钼合金364- 粉末冶金钼-0.5 % 钛-0.1 % 锆（TZM）合金。 1.1.5 钼365- 非合金真空电弧铸造钼，低碳。 1.1.6 钼合金366- 真空电弧铸造钼-30 % 钨合金。 1.1.7 图纸等级- 定义了图纸等级，买方可将其作为单独要求指定。 1.2 单位——以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 1.2.1 球冲头变形试验要求 8.4 是指英寸-磅系统中规定的测试，以及用于产生 图2 都是通过英寸-磅的测量获得的。因此，其原始英寸-磅系统中保留了作为板材厚度函数的最小所需杯高图。 已扫描图形数据，并在扫描数据上拟合了一条直线。这条线的方程式包括英寸-磅和国际单位制。 1.3 以下预防性警告仅适用于本规范的试验方法部分: 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。

1.1 This specification covers unalloyed molybdenum and molybdenum alloy plate, sheet, strip, foil, and ribbon as follows: 1.1.1 Molybdenum 360— Unalloyed vacuum arc-cast molybdenum. 1.1.2 Molybdenum 361— Unalloyed powder metallurgy molybdenum. 1.1.3 Molybdenum Alloy 363— Vacuum arc-cast molybdenum-0.5 % titanium-0.1 % zirconium (TZM) alloy. 1.1.4 Molybdenum Alloy 364— Powder metallurgy molybdenum-0.5 % titanium-0.1 % zirconium (TZM) alloy. 1.1.5 Molybdenum 365— Unalloyed vacuum arc-cast molybdenum, low carbon. 1.1.6 Molybdenum Alloy 366— Vacuum arc-cast molybdenum-30 % tungsten alloy. 1.1.7 Drawing Grade— A drawing grade is defined, which may be specified as a separate requirement by the purchaser. 1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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. 1.2.1 The ball punch deformation test called for in 8.4 is a test that is specified in the inch-pound system, and original test results used to produce Fig. 2 were all obtained using inch-pound measurements. For this reason, the graph of minimum required cup height as a function of sheet thickness has been retained in its original inch-pound system. The graphical data has been scanned and a straight line fitted to the scan data. The equation of this line is included in both inch-pound and SI units. 1.3 The following precautionary caveat pertains only to the test method portions of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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.
