Product Code:SAE ARP900
Title:Methods for Evaluating Cryogenic Filters
Issuing Committee:A-6c1 Contamination And Filtration Committee
Scope:The purpose of this test procedure is to present test methods that can be utilized to evaluate the filtration and operating characteristics of filters that will be utilized in a cryogenic system. The methods presented herein are intended to supplement standard filter testing specifications to allow evaluation of filter performance characteristics in areas that could be affected by extreme low temperatures. The test methods can be utilized to evaluate filters up to and including 60 gpm (230 lpm) capacity. If higher flow rate filters are to be evaluated in accordance with the test methods presented herein, it will be necessary to increase the system flow capacity and the size of effluent sampling system. The test methods presented herein do not encompass testing of cryogenic bypass relief valves, delta P indicators, gages, or components other than a basic filter housing and element. This procedure includes equivalent metric units (in parentheses) as reference information, where deemed useful.
