1.1These 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 – 14 |
| Test Method B—Nanofiltration Devices | 15 – 21 |
| Test Method B—Seawater Reverse Osmosis Devices | 22 – 28 |
1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3This 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.
1.4This 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.
