Title:Aerospace - Dynamic Test Method for Determining the Relative Degree of Cleanliness of the Downstream Side of Filter Elements (NONCURRENT Jun 2008)
Issuing Committee:A-6c1 Contamination And Filtration Committee
Scope:This SAE Aerospace Recommended Practice (ARP) describes a procedure for determining the insoluble contamination level of the downsteam side of filter elements. Results of this procedure represent the particulate released from the tested filter element under the prevailing conditions of the test. The results may be used for comparative evaluation of the effectiveness of various cleaning methods or the cleanliness of elements after cleaning or as received from manufacturers.【英文标准名称】:StandardTestMethodforEvaluatingtheMicrostructureofGraphiteinIronCastings
