Emissions of dangerous substances from construction materials and the CE marking; new requirements for manufacture



​The CE marking becomes mandatory for construction products upon entry into force of the Construction Product Regulation (CPR) on 1 July 2013. Over the next few years, the CE marking will also introduce changes to requirements related to the emission of dangerous substances from construction products. 

The testing standard currently being finalised will introduce uniform requirements for the emission of dangerous substances from construction products across the EU Member States. As a result, construction material manufacturers in Finland will also face new testing requirements.

The M1 marking already widely used in Finland has been an effective means of reducing emissions and improving indoor air quality. More than 2,200 products have already obtained the voluntary marking. “The marking is widely used for surface materials available in Finland, such as paints, but also fillers, insulators and body structures. In practice, it is possible to construct an entire building using only materials that carry the M1 marking,” says Senior Expert Helena Järnström from VTT Expert Services Ltd.

M1 will not serve in the future with the introduction of increasingly strict requirements 

Finnish construction material manufacturers are already familiar with determining the emission values of their products. However, the new requirements of the CE marking will be stricter, for example concerning individual compounds, than those of the M1 marking. Instead of declaring one emission value, individual values must be declared for each compound if the product is marketed in all EU countries.

Changes may also apply to the time of testing. For the M1 marking, products undergo testing at four weeks of age. The new requirements will also require testing at three days. This applies in particular to products sold to German customers. In the future, manufacturers should have the results of two tests performed at different times. The testing schedules for CE marking are, however, still under development at EU level.

The new emission requirements will not apply to the CE marking of construction materials until 2015. “However, these new requirements should be considered nowtoday while new products are being developed. This helps eliminate surprises later when the product is already on the market and the new requirements enter into force,” says Järnström.

VTT Expert Services is an expert in emission measurements

Our services enable you to verify that your products meet both current and future requirements for the emission of dangerous substances. You can determine the characteristics according to the national classification (M1), or prepare in advance for the future new requirements of the CE marking. 

Our services include the following

  • Emission measurement of building materials in a laboratory (chambers range from 100 litres to 4.5 cubic metres) 
  • Emission measurements of building materials on site from actual structures 

VTT Expert Services Ltd performs accredited (T001) emission measurements according to the M1 classification testing protocol and the ISO 16000-9 standard, on which the future CE testing standard will be based. Our testing laboratory is approved by the Building Information Group and the Finnish Food Safety Authority Evira.
