1.1 These test methods cover the preparation of the sample and the determination of the concentration of phenolic compounds in water. They are based on the color reaction of phenol (C6H5OH) with 4-aminoantipyrine and any color produced by the reaction of other phenolic compounds is reported as phenol. The concentration of phenol measured represents the minimum concentration of phenolic compounds present in the sample.
1.2 Phenolic compounds with a substituent in the para position may not quantitatively produce color with 4-aminoantipyrine. However, para substituents of phenol such as carboxyl, halogen, hydroxyl, methoxyl, or sulfonic acid groups do produce color with 4-aminoantipyrine.
1.3 These test methods address specific applications as follows:
Range

1.4 It is the users' responsibility to assure the validity of the standard test method for use in their particular matrix of interest.
1.5 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements see 6.3.2 and 8.6.
1.7 This 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.
