Reliability of VOC emission chamber testing/Zuverlässigkeit von VOC-Emissionskammerprüfungen – Ringversuch mit Kunstharz-Bodenbeschichtung, Parkettlack und Silikondichtstoff

Abstract

The Association for the Control of Emissions in Products for Flooring Installation, Adhesives and Building Materials (GEV) organised a round robin test in 2020 with the purpose to update its list of recommended testing laboratories on the basis of test results. 43 laboratories from 15 countries received 3 test products, a synthetic resin floor coating, a parquet lacquer and a silicone sealant. The results of the GEV round robin test 2020 showed a similar variation of the results as in a previous round robin test of the GEV in 2017 without any significant improvement. The large variation of the results confirms the limited significance of single test results. This is why GEV discloses VOC emissions only in terms of broad emission classes. Within this limitation, the performance of 19 laboratories was rated to be good by GEV. Currently, a list of recommended testing laboratories for GEV emissions testing comprises 15 laboratories from 4 countries. These laboratories performed well in this round robin test and presented an appropriate accreditation according to ISO/IEC 17025.
