1.1 蒸汽水合试验方法可用于研究玻璃和微晶玻璃等废物体的腐蚀 2. 在高温下暴露于水蒸气时。此外，形成的变更阶段可以用作存储库条件下可能形成的阶段的指标。这些测试；允许在高比表面积溶液体积比下改变玻璃；提供有关形成的蚀变阶段、放射性和危险成分的处置以及特定试验条件下的蚀变动力学的有用信息。该信息可用于性能评估（McGrail等人，2002年） ( 1. ) 3. 例如）。 1.2 该测试方法必须按照数据验收的所有质量保证要求进行。 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 蒸汽水化试验可用于研究玻璃和玻璃陶瓷废物体在高温和水蒸汽或水薄膜接触条件下的腐蚀。 这种方法可以作为一些材料的加速试验，因为高温会加速热激活过程。文献中报告了范围广泛的测试温度–40°C（Ebert等人，2005年） ( 3. ) ，例如）至300°C（Vienna等人，2001年） ( 4. ) ，例如）。应注意的是，随着试验温度的升高，有可能改变腐蚀速率决定机制和在改变时形成的相类型，而不是在处置环境中发生的（Vienna等人，2001） ( 4. ) ). 5.2 蒸汽水合试验可用作筛选试验，以确定废物体的改变倾向，并对废物体之间的改变率进行相对比较。

1.1 The vapor hydration test method can be used to study the corrosion of a waste forms such as glasses and glass ceramics 2 upon exposure to water vapor at elevated temperatures. In addition, the alteration phases that form can be used as indicators of those phases that may form under repository conditions. These tests; which allow altering of glass at high surface area to solution volume ratio; provide useful information regarding the alteration phases that are formed, the disposition of radioactive and hazardous components, and the alteration kinetics under the specific test conditions. This information may be used in performance assessment (McGrail et al, 2002 ( 1 ) 3 for example). 1.2 This test method must be performed in accordance with all quality assurance requirements for acceptance of the data. 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 vapor hydration test can be used to study the corrosion of glass and glass ceramic waste forms under conditions of high temperature and contact by water vapor or thin films of water. This method may serve as an accelerated test for some materials, since the high temperatures will accelerate thermally activated processes. A wide range of test temperatures have been reported in the literature –40°C (Ebert et al, 2005 ( 3 ) , for example) to 300°C (Vienna et al, 2001 ( 4 ) , for example). It should be noted that with increased test temperature comes the possibility of changing the corrosion rate determining mechanism and the types of phases formed upon alteration from those that occur in the disposal environment (Vienna et al, 2001 ( 4 ) ). 5.2 The vapor hydration test can be used as a screening test to determine the propensity of waste forms to alter and for relative comparisons in alteration rates between waste forms.
