ASTM D5090-90(2001)

Standard Practice for Standardizing Ultrafiltration Permeate Flow Performance Data

SCOPE
1.1 This practice covers the standardization of permeate flow for ultrafiltration (UF) systems.
1.2 This practice is applicable to natural waters including brackish waters, seawaters, and ultrapure waters including those used in power generation and microelectronics and pharmaceuticals production. It is not necessarily applicable to waste waters.
1.3 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.
