1.1''This test method covers a rapid and simple field determination of carbon dioxide in natural gas pipelines. Available detector tubes provide a total measuring range of 100 ppm (parts per million) up to 60'''% by volume, although the majority of applications will be on the lower end of this range (that is, under 5'''%). At least one manufacturer provides a special kit for measurements from 10 to 100'''% CO2, but the normal 100'''cc hand pump is not used. See Note 1.
Note 1:''High-range carbon dioxide detector tubes will have measuring ranges in percent (%) CO2, and low-range tubes will be in parts per million (ppm). To convert percent to ppm, multiply by 10'''000 (1'''%'''='''10'''000 ppm).
1.2''Units'''The values stated in SI units are regarded as standard. The inch-pound units in parentheses are for information only.
1.3''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.
1.4''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.
