BS ISO 13357-2:2017规定了干燥润滑油可过滤性的评估程序， 尤其是那些为液压应用而设计的。本程序仅适用于矿物基材料 油，因为用其他材料制造的液体（例如耐火液体）可能不兼容 使用指定的测试膜。使用粘度高的润滑油对其应用范围进行了评估 符合ISO 3448中定义的ISO粘度等级（VG）100。在所述范围内，可过滤性如下 定义的粘度不取决于油的粘度。 该程序不适用于某些液压油 通过使用不溶性/部分可溶性添加剂赋予其特定性质，或 通过特别大的分子物种。注:过滤性是液压系统中使用的润滑油的一项基本要求，因为 此应用程序中使用的过滤器。本文件定义了评估干油可过滤性的方法。需要注意的是 一些油在有污染水的情况下表现出较差的过滤特性。 ISO 13357- 1[2]适用于研究水和高温对过滤性的影响，如果 在油中可能存在水的应用中使用油。交叉引用:ISO 3696:1987ISO 1219-1:2012ISO 3448:1992ISO 4788:2005 Ed 2ISO 3170:2004 Ed 3 ISO 13357-1:2017ISO 4259:2006 Ed 3购买本文件时提供的所有现行修订均包含在购买本文件中。

BS ISO 13357-2:2017 specifies a procedure for the evaluation of the filterability of dry lubricating oils, particularly those designed for hydraulic applications. The procedure only applies to mineral-based oils, since fluids manufactured from other materials (e.g. fire-resistant fluids) might 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.This document defines a method for assessing the filterability of dry oils. It is necessary to note that some oils exhibit poorer filterability characteristics in the presence of contaminating water. ISO 13357-1[2] applies to the investigation of the effect of water and high temperature on filterability, if an oil is used in applications where the presence of water in the oil is likely.Cross References:ISO 3696:1987ISO 1219-1:2012ISO 3448:1992ISO 4788:2005 Ed 2ISO 3170:2004 Ed 3 ISO 13357-1:2017ISO 4259:2006 Ed 3All current amendments available at time of purchase are included with the purchase of this document.
