Abstract
Overview
ISO 4548-4:1997 specifies standardized test methods for measuring the initial particle retention efficiency, life, and cumulative efficiency of full‑flow lubricating oil filters for internal combustion engines using the . It defines test rig configuration, test liquids, test contaminants, sample preparation and procedures, and reporting requirements so manufacturers, test laboratories and engine OEMs can consistently assess filter performance (single‑pass retention and particle‑holding life).
