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 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 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 and health practices and determine the applicability of regulatory limitations prior to use.
