D3824-95(2005) Standard Test Methods for Continuous Measurement of Oxides of Nitrogen in the Ambient or Workplace Atmosphere by the Chemiluminescent Method
| Published By | Publication Date | Number of Pages |
| ASTM | 2005 | 12 |
1.1 These test methods cover procedures for the continuous determination of total nitrogen dioxide (NO 2 ) and nitric oxide (NO) as NO x , or nitric oxide (NO) alone or nitrogen dioxide (NO 2 ) alone, in the ranges shown in the following table:
Note 1–Approximate range: 25 o C and 101.3 kPa (1 atm).
1.2 The test methods are based on the chemiluminescent reaction between nitric oxide and ozone.
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 and health practices and determine the applicability of regulatory limitations prior to use. For specific precautionary statements, see Section 9.
