1.1 This test method describes the sampling and continuous analysis of ozone (O 3 ) in the atmosphere at concentrations ranging from 10 to 2000 μg/m³ of O 3 in air (5 ppb(v) to 1 ppm(v)). 1.1.1 The test method is limited to applications by its sensitivity to interferences as described in Section 6 . The interference sensitivities may limit its use for ambient and workplace atmospheres. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use.
