measure is crucial to the VOC measurement problem. 2.1.1 Concentration Limits A concentration based VOC standard is often listed as parts per million corrected to a percentage of diluent flue gas such as oxygen (i.e. ppm @7% O 2). The standard has usually been defined by the same test method that will be used to prove compliance with the standard.
At room temperature the properties of VOC cause these compounds to vaporize, evaporate, or sublimate from the liquid or solid form, allowing them to escape into the atmosphere.
