1.1 本试验方法涵盖了测定离子电阻率的预处理、试验条件、仪器和程序，在电池行业中通常称为浸入40%电解质中的碱性电池分离器的电阻（ER） % 氢氧化钾（KOH）。 1.2 以国际单位制表示的数值应视为标准。 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 电池分离器的ER是分离器和电池制造商用于质量控制和分离器选择的标准测量值。 5.2 分离器ER和分离器与电解液的相互作用（即抗润湿或流动）将导致蓄电池的内阻，这有可能限制蓄电池的电输出。 ER测定是电池制造商在设计、材料选择和性能规范中使用的工具。 5.3 分离器引起的镀液电阻变化受分离器孔结构的孔隙率、厚度和弯曲度、分离器对电解液的润湿性以及电解液的温度和浓度的影响。 5.4 孔隙结构的不完全润湿或饱和限制了从分离器结构获得的最低ER值。对分离器进行预处理，以确保被测样品已充分润湿。 未完全润湿（饱和）的分离器将产生更高的ER。 5.5 该测试方法旨在提供快速且可重复的测量，以近似于在电池中使用分离器时可能发生的ER变化。

1.1 This test method covers the pretreatment, test conditions, apparatus, and procedure to determine the ionic resistivity, commonly referred to in the battery industry as electrical resistance (ER) of an alkaline battery separator immersed in an electrolyte of 40 % potassium hydroxide (KOH). 1.2 The values stated in SI units are to be regarded as the 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 The ER of a battery separator is a standard measurement used by separator and battery manufacturers for quality control purposes and separator selection. 5.2 Separator ER and the separator's interaction with the electrolyte, that is resistance to wetting or flow, will contribute to the internal resistance of the battery and this has the potential to limit the electrical output of a battery. The ER determination is a tool for battery manufacturers to use in design, material selection, and performance specifications. 5.3 The change in the bath electrical resistance imparted by a separator is affected by the porosity, thickness, and tortuousity of the pore structure of the separator, the wettability of the separator to the electrolyte, and the temperature and concentration of the electrolyte. 5.4 Incomplete wetting or saturation of the pore structure limits the lowest ER value obtainable from a separator structure. Separators are pretreated to assure that the specimen being tested has been adequately wetted out. A separator that is not fully wetted out (saturated) will give a higher ER. 5.5 This test method is intended to give a rapid and repeatable measurement that approximates the change in ER that could happen when the separator is used in a battery.
