WebVOCs are chemical compounds – mixtures of more than one element – where one of the elements is carbon. They are described as volatile because they evaporate easily, releasing molecules into the atmosphere. In some places, notably California (and previously in the USA as a whole), VOCs are known as ROGs or reactive organic gases. WebCriteria. 1. Gases, which at 20°C (68°F) and a standard pressure of 101.3 kPa (14.7 psi): (a) are ignitable when in a mixture of 13% or less by volume in air; or. (b) have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit. 2.
