1.1 本试验方法涵盖了从饮用玻璃器皿的边缘和边缘区域用乙酸提取的铅和镉的测定，该玻璃器皿外部用陶瓷玻璃搪瓷装饰。萃取过程可能会加速装饰区域中铅和镉的释放，因此，作为一种严格的测试，在此类玻璃器皿的实际使用条件下不太可能匹配。本试验方法针对铅和镉。 注1: 有关更多信息，请参阅测试方法 C738 . 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 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。 ====意义和用途====== 5.1 众所周知，如果摄入过量，重金属铅和镉会对人体健康造成严重影响。因此，重要的是测量可能从与嘴唇接触的玻璃饮用容器区域中提取的量。即使通过本试验方法提取的铅和镉的量决不能代表通过实际唇接触提取的金属量，但从一个试样中提取的金属相对于另一个试样的相对数量提供了一个有效的判别工具。

1.1 This test method covers the determination of lead and cadmium extracted by acetic acid from the lip and rim area of glassware used for drinking and which is exteriorly decorated with ceramic glass enamels. The procedure of extraction may be expected to accelerate the release of lead and cadmium from the decorated area and to serve, therefore, as a severe test that is unlikely to be matched under the actual conditions of usage of such glassware. This test method is specific for lead and cadmium. Note 1: For additional information see Test Method C738 . 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 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. ====== Significance And Use ====== 5.1 The heavy metals, lead and cadmium, are known to cause serious health effects in man if consumed in excess. It is, therefore, important to measure the amount that may be extracted from an area of the glass drinking vessel in contact with the lip. Even though the amount of lead and cadmium extracted by this test method is in no way representative of the amount of the metals extracted by actual lip contact, the relative magnitude of metals extracted from one test specimen in relation to another test specimen provides an effective tool for discrimination.
