Reliability of VOC emission chamber testing – A round-robin test with a parquet adhesive, a parquet lacquer, and a levelling compound/Zuverlässigkeit von VOC-Emissionskammerprüfungen – Ein Ringversuch mit einem Parkettklebstoff, einem Parkettlack und einer Verlaufsspachtelmasse

Abstract

The Association for the Control of Emissions in Products for Flooring Installation, Adhesives and Building Materials (GEV) organised a round-robin test in 2023 with the purpose to update its list of recommended testing laboratories based on test results. 39 laboratories from 11 countries tested the VOC emissions of 3 test products, a parquet adhesive, a parquet lacquer, and a levelling compound. The GEV round- robin test 2023 showed a similar variation of the test results as had been observed in previous round-robin tests in 2017 and 2020. The variation of the test results confirms the limited significance of single test results. This is why GEV discloses VOC emissions only in terms of broad emissions classes. The performance of 22 laboratories was rated by GEV to be good. Currently, a list of recommended testing laboratories for GEV emissions testing comprises 18 laboratories from 6 countries. These laboratories met the performance requirements of GEV in the round-robin test and presented an accreditation of this testing protocol according to ISO/IEC 17025.
