EU Decopaint Directive amended with alternative test method

For products that are containing 15% solvents or more, now ISO 11890-1 method is accepted as alternative method (determination of total volatiles by monitoring weight loss during 1 hour heating at 110 °C). Use of ISO 11890-2 continues to be possible, too. Only in the presence of reactive diluents, ASTM 2369 shall be used and no other standard is accepted for Decopaint purposes (Directive 2010/79/EU of 19 November 2010).


European “Decopaint” Directive (2004/42/EC) is limiting the total content of VOCs in certain paints and varnishes and in vehicle refinishing products for reducing VOC emissions and thus reducing generation of ozone in lower atmosphere.

VOC content is measured in Europe by direct injection into gas chromatograph (ISO 11890-2). Reactive products are allowed to stand open for 1 hour after mixing before start of test for allowing first curing to happen, then VOC content is determined as total volatiles by monitoring weight loss during 1 hour heating at 110 °C (ASTM D2369, in analogy to most recent version of ISO 11890-1). In both cases no subtraction of neither water nor exempt compounds is performed, in contrast to corresponding US test methods.

Now weight loss determination also is accepted for products with 15% or more solvent content. This improves determination of VOC content for high solvent products.
