Scope of standard

1.1 This test method is applicable to the determination of the carbon monoxide (CO) concentration of the atmosphere between 0.6 mg/m³ (0.5 ppm(v)) and 115 mg/m³ (100 ppm(v)). The measuring principle is based on the absorption of infrared radiation by CO in the 4.7 μm region (1).2 1.2 The test method has a limit of detection of about 0.6 mg/m³ (0.5 ppm(v)) carbon monoxide in air. 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. See Section 9 for additional precautions. 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.
