GSO ISO 19438: 2011 Diesel fuel and petrol filters for internal combustion engines - Filtration efficiency using particle counting and contaminant retention capacity (ISO 19438: 2003)

The International Organization for Standardization (ISO). First edition. It is intended that ISO 19438 replace ISO/TS 13353:2002 when that document is reviewed after three years. This standard has been approved as a Gulf Standard without any technical modifications by GCC Standardization Organization (GSO). 50 р. This International Standard specifies a multi-pass filtration test, with continuous contaminant injection and using the on-line particle counting method, for evaluating 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.
