1.1These test methods cover procedures for the continuous determination of total nitrogen dioxide (NO₂) and nitric oxide (NO) as NO_x, or nitric oxide (NO) alone or nitrogen dioxide (NO₂) alone, in the ranges shown in the following table:

	Approximate Range of Concentration (25°C and 101.3 kPa (1 atm))

Gas	Ambient Atmosphere	Workplace Atmosphere
	μg/m³ (ppm)	mg/m³ (ppm)

NO	10 to 600 (0.01 to 0.5)	0.6 to 30 (0.5 to 25)
(NO + NO₂) = NO_x	20 to 1000 (0.01 to 0.05)	1 to 50 (0.5 to 25)
NO₂	20 to 1000 (0.01 to 0.5)	1 to 50 (0.5 to 25)

1.2The test methods are based on the chemiluminescent reaction between nitric oxide and ozone.

1.3The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.

1.4This 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 precautionary statements, see Section 9.

1.5This 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.
