(Test Method)Standard Test Method for Operating Characteristics of Home Reverse Osmosis Devices
Standard Test Method for Operating Characteristics of Home Reverse Osmosis Devices
SIGNIFICANCE AND USE
Home reverse osmosis devices are typically used to remove salts and other impurities from drinking water at the point of use. They are usually operated at tap water line pressure, with water containing up to several hundred milligrams per litre of total dissolved solids. This test method permits measurement of the performance of home reverse osmosis devices using a standard set of conditions and is intended for short-term testing (less than 24 h). This test method can be used to determine changes that may have occurred in the operating characteristics of home reverse osmosis devices during use, but it is not intended to be used for system design. This test method does not necessarily determine the device’performance when solutes other than sodium chloride are present. Use Practice D 4516 and Test Methods D 4194 to standardize actual field data to a standard set of conditions.
This test method is applicable for spiral-wound devices.
SCOPE
1.1 This test method covers determination of the operating characteristics of home reverse osmosis devices using standard test conditions. It does not necessarily determine the characteristics of the devices operating on natural waters.
1.2 This test method is applicable for spiral-wound devices.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
