Abstract Information :
Current and proposed worldwide regulations are mandating lower monitoring levels and/or control of VOC (volatile organic compound) gas emissions. With the ever-increasing awareness of the potential for negative health effects from the air we breathe, the requirements for low-level traceable calibration standards are becoming of greater importance. ISO 17025 and ISO 17034 Accreditation are an important step in the traceability of these multi-component low level VOC calibration standards. This presentation will focus on the production of gaseous multi-component ISO 17025 and ISO 17034 VOC calibration standards. This presentation will also focus on the process of determining the proper cylinder material and treatment process, evaluating the compounds of interest for compatibility, concentrations, stability, traceability and uncertainty.
