1.1 本试验方法包括测定活性混合床离子交换树脂筒用于去离子时的性能。该测试可用于确定未使用墨盒的初始容量或已使用墨盒的剩余容量。在这种情况下，性能定义为到两个定义端点的离子交换容量（或吞吐量）。该方法不测量有机物，也不试图确定滤筒可达到的最终水质。 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和健康实践，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 本试验方法可用于评估未使用的混合床离子交换盒是否符合规范。 5.2 本试验方法提供了根据处理至电导率终点的水量计算容量的方法。 5.3 书面试验方法假设滤芯中的离子交换树脂部分或全部转化为H + 或者哦 – 类型树脂再生不是该方法的一部分。 5.4 本试验方法提供了基于药筒的容量计算。 5.5 本试验方法可用于测试不同尺寸的混床树脂筒。改变试验水的流速和取样频率，以补偿试验筒中树脂的近似体积。

1.1 This test method covers the determination of the performance of mixed bed ion exchange resin cartridges in the active form when used for deionization. The test can be used to determine the initial capacity of unused cartridges or the remaining capacity of used cartridges. In this case performance is defined as ion exchange capacity (or throughput) to two defined endpoints. The method does not measure organics and does not attempt to determine the ultimate water quality attainable by the cartridge. 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 and health 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 This test method can be used to evaluate unused mixed bed ion exchange cartridges for conformance to specifications. 5.2 This test method provides for the calculation of capacity in terms of the volume of water treated to a conductivity end point. 5.3 The test method as written assumes that the ion exchange resins in the cartridge are either partially or fully converted to the H + or OH – form. Regeneration of the resins is not part of this method. 5.4 This test method provides for the calculation of capacity on a cartridge basis. 5.5 This test method may be used to test different size mixed bed resin cartridges. The flow rate of test water and the frequency of sampling are varied to compensate for the approximate volume of resin in the test cartridge.
