Coverage of the terms VOC and TVOC
- The dominating European definition comes from prEN 16516. It shall be used in any new national regulation on VOC emissions, as well as for CE marking. It is used in Belgian and French national regulations, and in several voluntary labels, such as EMICODE, M1, and Indoor Air Comfort.
- Traditionally, in ISO 16000-6 and part 9 standards, all measured emissions are VOCs that appear within the interval between and including n-hexane and n-hexadecane on a non-polar gas chromatographic column (which separates a mixture of VOCs into its individual ingredients). For experts: This is a 100 % methyl polysiloxane capillary GC column.
- This corresponds somehow (but not to 100%) to a volatility range of boiling points between and including 68°C and 287 °C at normal pressure (1013 hPa).
- prEN 16516 developed the ISO 16000 standards further in many aspects. To improve the detection of many VOCs, the analysis shall be run not on a non-polar gas chromatographic column, but on a slightly polar gas chromatographic column. For experts: This is a 5 % phenyl / 95 % methyl polysiloxane capillary GC column.
- In prEN 16516, the same limits of the VOC range are applied as for the non-polar column. This means that now all measured emissions are VOCs that appear within the interval between and including n-hexane and n-hexadecane on a slightly gas chromatographic column.
- As few substances that would be a VOC earlier now may fall out of that range on the slightly polar column, prEN 16516 contains an Annex G with a positive list: Any substance on that list is a VOC even if it lies outside the analytical VOC range when using the new GC column, the slightly polar one.
- This complication was necessary to obtain comparability with historical test results obtained on the non-polar GC column.
- Any substances that cannot be detected with the specified testing method are exempted by nature from the above definitions. The testing method includes adsorption of any emissions from the air on Tenax TA, thermal desorption and GC/MS (gas chromatography with mass spectrometric detection).
- CDPH method in California applies a broader VOC range: All measured emissions are VOCs that appear within the interval between and including n-pentane and n-heptadecane - without detailing a specific gas chromatographic column.
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 regulation, French VOC regulations, German VOC regulations, EMICODE, 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 mark, CE 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.
