Description of ASTM-D1608 2009ASTM D1608 - 98(2009)Standard Test Method for Oxides of Nitrogen in Gaseous Combustion Products (Phenol-Disulfonic Acid Procedures)Active Standard ASTM D1608 | Developed by Subcommittee: D22.03 Book of Standards Volume: 11.07
Translated Standard: Russian ASTM D1608Significance and Use This test method provides a means to measure the total nitrogen oxides (NO x ) content of gaseous emissions for purposes such as determining compliance with regulations, studying the effect of various abatement procedures on NO x emissions, and checking the validity of instrumental measurements. 1. Scope 1.1 This test method describes the phenol-disulfonic acid colorimetric procedure (1) 2 for the determination of total oxides of nitrogen [nitrous oxide (N 2 O) excepted] in gaseous effluents from combustion and other nitrogen oxidation processes. 1.2 It is applicable to a concentration range of oxides of nitrogen as nitrogen dioxide (NO 2 ) of 5 ppm to several thousand parts per million by volume (four to several thousand milligrams per dry standard cubic metre). 1.3 Since the grab sampling technique used takes a relatively small sample over a very short period of time, the result obtained will be an instantaneous measure of the nitrogen oxides and, therefore, will be representative of the emissions only if the gas stream is well mixed and the concentration constant with time. Multiple samples are recommended. 1.4 The values stated in SI units are to be regarded as standard. The SI equivalents are in parentheses and may be approximate. 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 more specific safety precautionary information see 8.5 and Section 3.)
