1.1 本指南介绍了一系列旨在检测颗粒离子交换材料的污垢和降解的测试和评估。提出了减少污垢和清洗树脂的建议。 1.2 本指南仅用于评估颗粒离子交换材料的性能，并不旨在解决性能不合格的所有可能原因。未解决机械和操作问题的评估。 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====== 4.1 除盐系统中使用的树脂可能会因许多因素而变质，包括化学侵蚀、有机和无机材料的污染、处理不当或老化的影响。检测降解或污垢对于确定除盐器性能差的原因可能很重要。

1.1 This guide presents a series of tests and evaluations intended to detect fouling and degradation of particulate ion exchange materials. Suggestions on reducing fouling and on cleaning resins are given. 1.2 This guide is to be used only as an aid in the evaluation of particulate ion exchange material performance and does not purport to address all possible causes of unsatisfactory performance. The evaluations of mechanical and operational problems are not addressed. 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 ====== 4.1 Resins used in demineralization systems may deteriorate due to many factors including chemical attack, fouling by organic and inorganic materials, mishandling, or the effects of aging. Detection of degradation or fouling may be important in determining the cause of poor demineralizer performance.
