标准范围

ISO 19438:2003规定了连续注入污染物并使用在线颗粒计数法的多道过滤试验，用于评估内燃机燃料过滤器在恒定试验液体流速下的性能。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。ISO 19438:2003适用于额定流量在50 l/h和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，经过一些修改，该程序允许应用于具有更高流速的燃油过滤器。

ISO 19438:2003 specifies a multi-pass filtration test, with continuous contaminant injection and using the on-line particle counting method, for evaluating the performance of fuel 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. ISO 19438:2003 is applicable to filter elements having a rated flow of between 50 l/h and 800 l/h; however, by agreement between filter manufacturer and customer, and with some modification, the procedure is permitted for application to fuel filters with higher flow rates.
