Scope

5.1 Reverse osmosis and nanofiltration desalinating devices can be used to produce potable water from brackish supplies (lt;108201;000 mg/L) and seawater as well as to upgrade the quality of industrial water. These test methods permit the measurement of the performance of reverse osmosis devices using standard sets of conditions and are intended for short-term testing (lt;24 h). These test methods can be used to determine changes that may have occurred in the operating characteristics of reverse osmosis and nanofiltration devices but are not intended to be used for plant design.

1.1 These test methods cover the determination of the operating characteristics of reverse osmosis devices using standard test conditions and are not necessarily applicable to natural waters. Three test methods are given, as follows:

	Sections
Test Method A—Brackish Water Reverse Osmosis Devices	8 – 13
Test Method B—Nanofiltration Devices	14 – 19
Test Method B—Seawater Reverse Osmosis Devices	20 – 25

1.2 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.
