标准范围

ISO 13357-1:2017规定了在有水的情况下评估润滑油（尤其是为液压应用设计的润滑油）可过滤性的程序。该程序仅适用于矿物油，因为由其他材料（例如耐火液体）制成的液体可能与规定的测试膜不兼容。根据ISO 3448的定义，使用粘度高达ISO粘度等级（VG）100的机油对应用范围进行了评估。在所述范围内，定义的可过滤性不取决于油的粘度。该程序不适用于某些液压油，这些液压油通过使用不溶性/部分溶解的添加剂或特别大的分子种类而具有特殊性能。注:由于液压系统中使用了细滤器，因此可过滤性是液压系统中使用的润滑油的主要要求。ISO 13357-1:2017定义了一种在存在污染水的情况下评估机油可过滤性的方法。需要注意的是，在这些条件下，一些机油的过滤性能较差。ISO 13357？2[1]用于研究油的可过滤性，该油用于油中不可能存在水的应用中。在存在污染水的情况下具有良好过滤性的油在干燥条件下不一定具有同样良好的过滤性。只有在潮湿时才具有良好过滤性的油不太可能被普遍接受。

ISO 13357-1:2017 specifies a procedure for the evaluation of the filterability of lubricating oils, particularly those designed for hydraulic applications, in the presence of water. The procedure only applies to mineral-based oils, since fluids manufactured from other materials (e.g. fire-resistant fluids) may not be compatible with the specified test membranes. The range of application has been evaluated with oils of viscosity up to ISO viscosity grade (VG) 100, as defined in ISO 3448. Within the range described, the filterability as defined is not dependent on the viscosity of the oil. The procedure is not suitable for some hydraulic oils on which specific properties have been conferred by the use of insoluble/partially soluble additives, or by particularly large molecular species.NOTE Filterability is a prime requirement for lubricating oils used in hydraulic systems because of the fine filters used in this application.ISO 13357-1:2017 defines a method for assessing the filterability of oils in the presence of contaminating water. It is noted that some oils will exhibit poorer filterability characteristics in these conditions. ISO 13357？2[1] is used to investigate the filterability of an oil which is used in applications where the presence of water in the oil is unlikely. An oil which has good filterability in the presence of contaminating water will not necessarily have equally good filterability in dry conditions. An oil having good filterability only when wet is unlikely to be generally acceptable.
