标准范围

ISO 4548-12:2017规定了连续注入污染物的多道过滤试验，并使用在线颗粒计数法评估内燃机全流量润滑油过滤器的性能。本文件的范围仅限于稳态条件，不涉及流量波动。该测试程序确定了过滤器的污染物容量、颗粒物去除特性和压差。本试验适用于粒度大于10μm时效率低于99%的滤芯。注:需要在一个试验台或多个试验台上安装几个试验流量回路，以覆盖2 l/min至600 l/min的整个流量范围。

ISO 4548-12:2017 specifies a multi-pass filtration test with continuous contaminant injection and using the online particle counting method for evaluating the performance of full-flow lubricating oil filters for internal combustion engines. The scope of this document is limited to steady state conditions and does not address fluctuations in the flow rate.The test procedure determines the contaminant capacity of a filter, its particulate removal characteristics and differential pressure.This test is intended for application to filter elements with an efficiency of less than 99 % at particle size greater than 10 μm.NOTE Several test flow loops built into one test rig, or several test rigs, would be necessary to cover the complete flow range of 2 l/min to 600 l/min.
