1.1 这些试验方法包括测定离子交换树脂用于水处理时的物理和化学性质。它们用于测试新材料和旧材料。包括以下十三种试验方法: 小节 试验规程A-预处理 6 – 10 试验方法B-保水能力 11 – 18 试验方法C-反洗和沉降密度 19 – 26 试验方法D-粒度分布 27 – 35 试验方法E-阳离子交换树脂的盐分解能力 36 – 45 试验方法F-阳离子交换树脂的总容量 46 – 55 试验方法阳离子交换树脂中氢的再生百分比 56 – 64 试验方法H-阴离子交换树脂的总分解能力和盐分解能力 65 – 73 试验规程I-阴离子交换树脂的再生百分比 74 – 82 试验规程J-阴离子交换树脂的氯离子含量 83 – 90 试验方法K-阴离子交换树脂的碳酸盐含量 91 – 99 阴离子交换树脂中L-硫酸盐含量的试验方法 100 – 108 试验规程M-阴离子交换树脂的总阴离子容量 109 – 117 1.2 以国际单位制表示的数值应视为标准值。括号中给出的值是英寸-磅单位的数学转换，仅供参考，不被视为标准值。 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。 第节给出了具体的预防说明 10.8 . 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====== 7.1 离子交换材料的离子形式影响其等效质量和平衡含水量。这些反过来会影响交换容量测定、密度测量和颗粒尺寸中获得的数值。因此，为了为比较提供统一的基础，应在分析之前将样品转换为已知的离子形式。该程序规定在分析之前将阳离子交换材料转化为钠形式，将阴离子交换材料转化为氯化物形式。之所以选择这些形式，是因为它们允许对样品进行称重和干燥，而无需担心空气污染或分解。如果使用其他离子形式，则应在报告结果时注意这一事实。

The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered 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. Specific precautionary statements are given in Section 10.8 . 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 ====== 7.1 The ionic form of an ion-exchange material affects both its equivalent mass and its equilibrium water content. These in turn influence the numerical values obtained in exchange capacity determinations, in density measurements, and in the size of the particles. To provide a uniform basis for comparison, therefore, the sample should be converted to a known ionic form before analysis. This procedure provides for the conversion of cation-exchange materials to the sodium form and anion-exchange materials to the chloride form prior to analysis. These forms are chosen since they permit samples to be weighed and dried without concern for air contamination or decomposition. If other ionic forms are used this fact should be noted in reporting the results.
