Untersuchungen zur Etablierung der DIN EN 16516 als neue Referenznorm für die Prüfung von Formaldehydemissionen aus Holzwerkstoffen gemäß Chemikalien-Verbotsverordnung

摘要

DIN EN 16516 "Construction products: Assessment of release of dangerous substances - Determination of emissions into indoor air" was published as a harmonized European standard in January 2018. For the establishment of DIN EN 16516 as the new reference standard various emission tests were carried out with the aim to develop a new test procedure for the measurement of formaldehyde emissions from wood-based panels. The superior aim is to minimize the risk of exceeding the indoor air reference value for formaldehyde. The investigations showed some particularly high formaldehyde emissions, especially at higher loading and temperature and at low air change rates. One of the tested particle boards exceeded the formaldehyde limit value and should not have been sold in Germany. For the conversion of test values from DIN EN 717-1 to DIN EN 16516 a conversion factor of 2.0 was derived from the comparative investigations.
