Live, work, sleep — people spend approximately 90% of their time indoors. Reason enough to pay attention to the good quality of indoor air.
Emissions from building products represent a possible main source of impurities of indoor air. Energy-saving and air sealing building methods additionally intensify this problem.
Concrete legal requirements regarding emissions up until now only applied to floor mats and adhesives. With the publication the Building regulations list B part 1, edition 2005/3, floor coverings in Germany also require a Ü marking on the basis of a national proof of applicability (general permission for use in buildings), according to the standard EN 14041 (independent of their classification of their behaviour in the case of fire according to DIN EN 13501-1) for use in living rooms for reasons of health and environmental protection, in addition to CE marking. The principles for the health evaluation of building products are laid down in this regulation. In the context of this building permission, such products must be submitted to an emission test in the test chamber according to ISO 16000.
This is regulated in the "Principles for the health assesment of construction products used in interiors" by the German Institute for Structural Engineering (DIBt). The DIBt have laid down the requirements of the European Construction Products Directive (89/106/EU) for hygiene, environmental protection and health.
