German AgBB / DIBt regulation
AgBB specification and DIBt regulation
Germany published restrictions of VOC emissions from construction products.
The background to this is the EU Directive on Construction Products, to be superseded by Construction Products Regulation, requiring that no construction product should cause any harm to the occupants of a building. As the EU did not specifically detail this requirement, national regulations may interpret this differently. A German task force of public health authorities, the AgBB, presented an approach for implementing this part of the EU directive. The AgBB used and updated an earlier project on assessment of emissions from carpets (ECA no. 18), for producing its AgBB specifications.
German DIBt institute in Berlin, a public agency for construction products, used this approach for requiring low VOC emissions for CE marked floorings that are used in Germany. Now all floorings sold in Europe have to carry a CE mark in showing compliance with EN 14041. But for being installed in German buildings, these have to be approved by DIBt after fulfilling the supplementary DIBt requirements on emissions and carry the Ü mark.
Please find here latest notified version of DIBt regulation.
This regulation is valid also for parquet floorings (EN 14342), parquet coatings, other flooring adhesives, some other products, such as resin floorings, wall coverings, sports floors, and some more. External certification is not be required for coatings and adhesives. Instead, an annual re-testing will do.
Barrier to trade?
The European Commission requests Germany "to remove barriers to trade" and "to change current rules and practices (Bauregellisten) concerning construction products which today impose additional requirements for products covered by European harmonised standards, and bearing the CE marking. Such additional requirements are in breach of EU Single Market rules." Please see here more details.
Most recent list of NIK / LCI values
The requirements comprise limitations to emissions after a test piece was stored in a test chamber for 3 days and 28 days. The 3 days test is representative of a building renovation case with early re-occupancy and prohibits excessively high initial VOC emissions and the presence of carcinogens. The 28 days test is representative of long-term emissions.The AgBB approach sets limits for:
- Carcinogens after 3 and 28 days
- Total VOC after 3 and 28 days
- Total SVOC after 28 days
- Single VOC compounds with "LCl" limit values (NIK
in German ) after 28 days.
(188 NIK values have been published)
- Single VOC compounds without such limit values after 28 days.
When approaching a registration by DIBt the manufacturer must provide several documents, among that test results for VOC emissions. Test reports only from laboratories approved by DIBt are accepted, such as Eurofins Product Testing A/S. Afterwards an auditing and certification contract with a "ÜZ" body is required, with at least annual audit on-site and re-testing. Then the German Ü mark may be used for labelling. Ü stands for "Übereinstimmung" (compliance). Eurofins offers also these DIBt services as ÜZ body.
Eurofins is both approved test house and approved ÜZ certification body. AgBB / DIBt testing can be easily combined with tests for other labels such as French VOC regulations, French AFSSET guideline, German Blue Angel, Finnish M1 and US tests. Such combinations are saving money compared with separate testing for each of these purposes. If a resistance to fire test is needed for CE marking then Eurofins cooperates with a German partner, the MPA in Erwitte.
Eurofins offers documentation of compliance with above specifications on emissions of VOC and aldehydes by independent testing, certification ("ÜZ body"), and auditing for the Ü mark if required.
Eurofins also offers consulting services for helping companiesin communication with DIBt agency for clear understanding of DIBt requirements.
