What does VOC mean?

Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature. Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air. For example, formaldehyde, which evaporates from paint, has a boiling point of only -19 °C (-2 °F).

Indoor air quality and VOC emission testing

Below definitions are used for indoor air quality monitoring, and for VOC emission testing.

WHO World Health Organization

WHO, as cited in ISO 16000-6, defined VOC as any organic compound whose boiling point is in the range from (50 °C to 100 °C) to (240 °C to 260 °C), corresponding to having saturation vapour pressures at 25 °C greater than 100 kPa.

·ISO 16000-6, TC 351, French VOC regulations, AgBB, AFSSET and more

Total VOCs (TVOC) is defined in ISO 16000-6 and in forth-coming new EN standard (TC 351) as the sum of volatile organic compounds, sampled on Tenax TA, which elute from a non-polar or slightly polar gas chromatographic separation column between and including n-hexane and n-hexadecane (n-C6 - n-C16), quantified as toluene equivalent (meaning as if it were toluene). Only Germany uses a slightly different definition.

Attention: This covers any organic compound with a boiling ranging circa between 68 °C and 287 °C.

This is the definition mostly used for VOC emission testing throughout the world.

California specification Section 01350

Carbon-containing compounds (excluding carbon monoxide, carbon dioxide, carbonic acid, metallic carbides and carbonates and ammonium carbonate) with vapor pressures at standard conditions approximately ranging between those for n-pentane through n-heptadecane(n-C5 - n-C17). For the purposes of practice Section 01350, formaldehyde and acetaldehyde are considered to be VOCs.

Eurofins - unique services offered by world-wide market leader

Your Eurofins laboratory can advise you which tests are required for the different purposes and different labels. Testing is performed by Eurofins for most of the labels in Europe and also for USA related purposes - for a non-comprehensive list of labels please click here.

VOC emission testing by Eurofins Product Testing A/S is accredited by DANAK in accordance with ISO 17025 which is the prerequisite for an analytical laboratory - ISO 9001 certification will not be sufficient. For explanation of the difference please click here. Our accreditation is valid world-wide via mutual acceptance within ILAC.
