Guide to VOC testing: regulations, methods, and standards

Published September 19, 2023

Many governments and industry groups require testing to verify that volatile organic compound (VOC) concentrations and emissions from different materials do not exceed safe limits. In Europe, the main directives covering VOCs include the Paints Directive 2004/42/CE and the Industrial Emissions Directive 2010/75/EU.1 Volatile organic compounds can also fall under other legislation, such as those related to the composition, storage, and handling of fuels.

VOC testing is typically performed using gas chromatography techniques, such as GC-MS and GC-FID. Measurlabs offers analysis options for a diverse range of industries and sample materials.

What are volatile organic compounds?

VOCs are carbon-containing chemical compounds that vaporize at a relatively low temperature, generally at 250 °C or below.2 They include such compounds as methane, benzene, xylene, propane, butane, and formaldehyde. Some VOCs occur naturally, but many originate from human activities, main sources including transportation, industrial processes, and the use of organic solvents.3

Some VOCs can irritate the eyes and airways, and prolonged exposure may adversely impact the cardiovascular and neurological systems and increase the risk of cancer.4 VOCs are also prevalent environmental contaminants.

Testing VOC emissions from construction materials

The interiors of new buildings can experience high levels of VOCs emitted by new building materials, fittings, furnishings, and surface coverings. VOCs can also be found in existing buildings when new materials are introduced, such as during renovations. The relevant standardized test methods include EN 16516 for construction products and EN 717 for wood-based panels. VOC testing is necessary for construction materials to receive environmental certifications such as BREEAM and the Nordic Swan Ecolabel.5

VOCs in health tech

In medical device biocompatibility testing, the ISO 10993-18 standard is used to identify the chemical composition of the device and to estimate and control the risks associated with it, such as VOCs released by the device during clinical use. Measurlabs offers chemical characterization of medical devices covering a variety of substances, including VOCs, SVOCs, non-volatile organic compounds, and inorganic elements.

For devices with a breathing gas pathway, such as ventilators, additional testing is needed to evaluate VOC emissions the patient may be exposed to through the gas stream. These tests are generally performed by Part 3 of the ISO 18562 standard.

Testing toys and consumer products

Toys and consumer products can also be a source of volatile organic compounds. These can be tested using vessels such as Tedlar bags, sample cylinders with absorbents, pumps, and special filters. European Standard EN 71-11 specifies methods to analyze toys and toy materials, while the Paints Directive also applies to consumer products in Europe.

VOCs in food contact materials

Although materials that release VOCs are not typically used in food industries, they may inadvertently end up in food contact materials. Regulations (EC) No 1935/2004 and (EU) No 10/2011 require manufacturers to conduct a risk assessment of non-intentionally added substances (NIAS), including VOCs.6 The initial NIAS screening is usually performed using the GC-MS technique.

Fuel testing

In the EU, Directive 2009/30/EC lays down the technical specifications for gasoline, including the maximum concentrations of several VOCs.7 Compliance testing is performed using methods outlined in the EN 228 standard.

Environmental VOC testing

Water, soil, and other environmental samples can also be tested for VOCs. Relevant EPA standards include EPA Method 8260 for GC-MS testing and EPA Method 8015 for nonhalogenated organics using gas chromatography-flame ionization detection (GC-FID).
