Title:Evaluating Effectiveness of Filter Element Cleaning Methods
Issuing Committee:A-6c1 Contamination And Filtration Committee
Scope:The purpose of this document is to provide a tool for evaluating methods proposed for cleaning service-contaminated filter elements. The procedure set forth is particularly applicable to the cleaning of metallic filter elements, where the expense of replacement often makes cleanability a desirable consideration. This procedure is applicable only to the evaluation of cleaning methods proposed for removal of service dirt. It is not applicable to cleaning methods for built-in dirt, LOX cleaning, etc.This ARP presents a procedure for evaluating filter element cleaning methods with respect to contaminant removal and filter element degradation, and a procedure for checking durability of cleaning equipment. A referee cleaning method is also included.
