ASTM D5110-98(2010)

Standard Practice for Calibration of Ozone Monitors and Certification of Ozone Transfer Standards Using Ultraviolet Photometry

SIGNIFICANCE AND USE
The reactivity and instability of O3 preclude the storage of O3 concentration standards for any practical length of time, and precludes direct certification of O3 concentrations as Standard Reference Materials (SRMs). Moreover, there is no available SRM that can be readily and directly adapted to the generation of O3 standards analogous to permeation devices and standard gas cylinders for sulfur dioxide and nitrogen oxides. Dynamic generation of O3 concentrations is relatively easy with a source of ultraviolet (UV) radiation. However, accurately certifying an O3 concentration as a primary standard requires assay of the concentration by a comprehensively specified analytical procedure, which must be performed every time a standard is needed (9).  
This practice is not designed for the routine calibration of O3 monitors at remote locations (see Practices D5011).
SCOPE
1.1 This practice covers a means for calibrating ambient, workplace, or indoor ozone monitors, and for certifying transfer standards to be used for that purpose.
1.2 This practice describes means by which dynamic streams of ozone in air can be designated as primary ozone standards.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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. See Section 8 for specific precautionary statements.
