Description / Abstract:

This Standard applies to the measurement of the concentration of carbon monoxide in samples taken from ambient air, enclosed gas streams, and gases under pressure.

This Standard sets forth the following two applicable procedures for the measurement of the concentration of carbon monoxide:

(a) Non-dispersive Infrared Spectrometry, which is intended for use where concentrations of carbon monoxide are above 6 mg-m-3 at 25OC and 101.3 kPa (approximately 5 ppm) or where a high degree of accuracy is not required below that concentration (see Clause 3); and

(b) Gas Chromatography, which is intended primarily for use where accurate measurement of carbon monoxide is required at concentrations below 6 mg-rnb3 at 25OC and 101.3 kPa (see Clause 4 ) .

Note: AZZ concentrations ref erred to throughout this Standard are based on a temperature of 2S0C and an atmospheric pressure of 101.3 kPa unZess otherwise stated.
