标准摘要
[中文适用范围]： 本文件规定了多通道过滤测试，采用连续污染物注入并使用在线颗粒计数方法，以评估在测试液体恒定流量下的内燃机柴油和汽油过滤器的性能。 测试程序确定过滤器的污染物容量、颗粒去除特性和压差。 本文件适用于额定流量在50 l/h至800 l/h之间的滤芯；然而，根据过滤器制造商和客户之间的协议，并进行一些修改，该程序允许应用于具有更高流量的燃油过滤器。 [外文原描述]： This document specifies a multi-pass filtration test, with continuous contaminant injection and using the on line particle counting method, to evaluate the performance of diesel fuel and petrol filters for internal combustion engines submitted to a constant flow rate of test liquid. The test procedure determines the contaminant capacity of a filter, its particulate removal characteristics and differential pressure. This document is applicable to filter elements having a rated flow between 50 l/h and 800 l/h; however, by agreement between the filter manufacturer and customer, and with some modifications, the procedure is permitted for application to fuel filters with higher flow rates.
