The Importance of VOC Emission Testing

August 31, 2021


Studies have shown that people are increasingly spending more time in indoor environments. Continuous lockdown measures and stay at home orders to prevent the spread of COVID-19 has increased this time significantly.  Therefore, it has never been more important to ensure the indoor environment we live in is comfortable and safe for our health.

Indoor environment quality (IEQ) factors, such as air quality, temperature, and lighting impact human’s health, comfort, and productivity (1).

A key indicator of indoor air hygiene is the concentration of volatile organic compounds (VOC) in the air. VOCs are a group of chemicals that can be found in building and maintenance products such as paint, cleaning products, adhesives, carpet, and wood products. Chemicals in these products can easily evaporate into the air we breathe and adversely impact our health and overall wellbeing (2).

Studies conducted by the United States Environmental Protection Agency (EPA) show that people can be exposed to very high levels of pollutants when using products containing organic chemicals and that concentrations of these chemicals can remain at high levels in the air for a long time (3).

It is therefore important to ensure chemical products used for maintenance and building work, have undergone a VOC emission test and that the product’s VOC emission readings are under a safe threshold. For further information on VOC refer to the previously published Mapei Article ‘Innovations in Indoor Air Quality and Comfort: How to Identify low VOC Products’


There are several different testing methodologies that manufacturers may decide to test products for VOC emissions including GEV-EMICODE, Blue Angel, AgBB and the California Department of Public Health CDPH Standard Method.

A study conducted by Eurofins Denmark compares these testing protocols and show that GEV-EMICODE EC1 PLUS includes the strongest requirements on low VOC emissions, whilst CDPH method is much easier to fulfil (4).

Mapei Analytical central laboratory based in Milan, Italy is equipped with 12 emission chambers where products are analysed to ISO 16000 (Part 3,6 and 9) in terms of VOC emissions. This technique is used for both voluntary and mandatory schemes in Europe including GEV-EMICODE, Blue Angel, M1, Logo Sanitaire and U Mark.

Most Mapei products are certified by the GEV-EMICODE voluntary label. Thus, our customers can be confident that Mapei products are safe as they are tested under the strictest requirements for VOC emissions.


In Australia, Green Star is the leading rating system for sustainable buildings. This rating tool is managed by the Green Building Council of Australia (GBCA).

The latest Green Star rating tool “Green Star Buildings” offers a credit based on the project passing an onsite VOC emission test in addition to using products with low VOC content as a minimum requirement (Credit 13 - Exposure to Toxins). Green Star Buildings recommends projects to use products that have undergone a VOC emission test to mitigate the risk of failing an onsite VOC emission test.

Not only is Mapei confident that our products will not be the cause of failing an onsite VOC emissions test, but also that our products are safe to the installers as well as the end users.

VOC emissions test certificates can be found at the bottom of each product page on our website

The Mapei Australia Technical Department is always ready and available to assist project teams with any enquiry regarding sustainability.
