Standard Guide for Water Analysis for Reverse Osmosis Application

SCOPE
1.1 This guide covers the analyses that should be performed on any given water sample if reverse osmosis application is being considered.  
1.2 This guide is applicable to waters including brackish waters and seawaters but is not necessarily applicable to waste waters.  
1.3 This is a guide only and should not be construed as a delineation of all ions known to exist in waters.  
1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.
