The TVOC Issue

Sidebar Image

The TVOC (Total Volatile Organic Compounds) indicates the total emissions of volatile organic compounds (VOCs). This term

  • TVOC summarizes the emission of substances of very different nature;
  • TVOC therefore is not a parameter of toxicological relevance;
  • TVOC can nevertheless indicate the order of magnitude of all emissions of VOCs, to be used for hygienic purposes;
  • TVOC is a limitation besides the substance specific limit values ("LCI"); the TVOC limit includes the VOCs without LCI value as well.

The term TVOC likewise the underlying term VOC is defined in very different manners across the globe. When running a pan-European or even a global emission test, then the existing test data can be calculated in different manners such that the different TVOC definitions are met.

To compare TVOC emissions values, it can be valuable to understand the most important issues within that definition.

Summary

The state-of--the-art of TVOC determination in Europe is to sum all test results of any organic compound

  • that are listed in Annex G of prEN 16516, and/or those
  • that appear within the interval between and including n-hexane and n-hexadecane on a slightly polar gas chromatographic column (which separates a mixture of VOCs into its individual ingredients),
  • using the individual results when they are expressed in toluene equivalents.

The German approach of TVOC determination ("TVOCSPEZ") is to sum all test results of any organic compound

  • that appear within the interval between and including n-hexane and n-hexadecane on a slightly polar gas chromatographic column (which separates a mixture of VOCs into its individual ingredients),
  • using the individual results for all VOCs with a German LCI value when they are calculated with their authentic standards,
  • and using the individual results for any VOCs without a German LCI value (including the non-identified VOCs) when they are expressed in toluene equivalents.

Both calculations can be made from the same set of test data, but they are not inter-comparable and deliver systematically different results.

Eurofins VOC related services

Eurofins offers documentation of compliance with the specifications on emissions of VOC and aldehydes by independent and ISO 17025 accredited testing, and if relevant also with external surveillance (inspections, re-testing), and certification, e.g. in combination with the Eurofins operated certification programme Indoor Air Comfort - certified products.

Eurofins operates both an accredited and notified test house and an approved ÜZ certification body. VOC emissions testing for any program or regulation can be easily combined with tests for other regulations or labels such as Belgian VOC regulationFrench VOC regulationsGerman VOC regulationsEMICODE, German Blue Angel, Finnish M1 and US tests. Such combinations allow to save money compared with separate testing for each of these purposes.

Certification and testing services for Ü markCE mark and the Eurofins certification program Indoor Air Comfort - certified products can be ordered in parallel for use on different market segments - there will be significant costs saving when compared to ordering these services separately.
