1.1 This test method covers the determination of the odor (that is, the property that affects the sense of smell) of water. A suggested system for classifying odors is given as . The test method is applicable to the determination of odor intensity in terms of odor intensity index or threshold odor number.
1.2 Effluents may carry a myriad of compounds, difficult to measure individually, which contribute to odor problems. Combinations of compounds can cause an odor intensity or develop a characteristic that cannot be anticipated from odors of the individual substances.
1.3 Because of the variation in human sensitivity, high precision in determining odor intensity is not possible. There will not always be agreement on odor characteristics by various testers. Odor analysis provides the tool to measure variation in odor intensity at a given sampling point. The degree of variation may indicate the magnitude or importance of an odor problem. Determining the cause of the variation or the source of the objectionable characteristic may define the odor problem better than analysis for individual compounds.
1.4 The values stated in SI or inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 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. For specific hazard statements, see the warning statement under .
