1.1 本规范 2. 涵盖三个等级的无缝和焊接锆管。 1.2 除非使用单个装置，例如腐蚀质量增益（mg/dm） 2. ，以英寸-磅或国际单位制表示的数值应单独视为标准值。每个系统中规定的值不是精确的等价物；因此，每个系统必须相互独立使用。SI值不能与英寸-磅值混合。 1.3 以下预防性警告仅适用于本规范的试验方法部分:本标准无意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 2 covers three grades of seamless and welded zirconium pipe. 1.2 Unless a single unit is used, for example corrosion mass gain in mg/dm 2 , the values stated in either inch-pound or SI units are to be regarded separately as standard. The values stated in each system are not exact equivalents; therefore each system must be used independently of the other. SI values cannot be mixed with inch-pound values. 1.3 The following precautionary caveat pertains only to the test methods 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.
