ASTM D7601-19 PDF

1.1 This practice covers the inspection, performance testing, autopsy, and analytical work associated with evaluating pressure driven membrane separation elements (microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO)).

1.2 This practice is applicable for elements when newly manufactured or at any time during their operation in a water treatment facility. The Analytical section (6.4) covers only membrane surface and foulant analyses.

1.3 The data derived from these tests should be evaluated versus newly manufactured elements/bundles or against operating systems when they were initially brought on-stream, or both. Industry norms can also be used for comparative purposes.

1.4 The values stated in inch-pound units are to be regarded as standard. No other units of measurement are included in this standard.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
