Round Robin Test for the Implementation of Odour Measurements regarding ISO 16000-28 into the Evaluation of Building Products – Part II (Specified by VDI 4302-1)


While in 2012 a commercially available acrylic sealant was used as sample material, in 2014 a lacquer doped with specific substances was sent to the participants for the VOC and odour measurement. The resulting measurement values for the perceived intensity were evaluated in consideration of various boundary conditions to identify parameters that could possibly influence the measurement procedure significantly. For the comparison of both interlaboratory comparisons qualified data sets were taken as a basis. Potential for improvement identified in 2012 was mainly confirmed by the interlaboratory test 2014 as well. Besides the accurate conduction as essential part of the measurement it became obvious again that the boundary conditions of the DIN ISO 16000-28 are not defined tight enough. Moreover the thesis that measurements based on the utilisation of comparison scales with only one funnel generate results especially imprecise could not be verified. Both interlaboratory comparisons resulted in relative standard deviations of reproducibility that lay between 20 and 40 % and such are quite comparable with those of well-established interlaboratory VOC comparisons.
