摘要

Investigations were made in order to confirm the comparability of four different emission test chamber and cell types for VOC and SVOC emission measurements. The emission test chambers were different in size (1m3 and 0,02m3) and material (stainless steel and glass). The emission test cells were also different in size (1,0 litre and 0,035 litre) and material (glass and stainless steel). The area specific air flow rate q was adjusted in all cases to 1,25 m3/m2h, climate was 23℃ and 50 % relative humidity. Different construction materials were tested over a time period of 28 days. Sampling of VOCs and SVOCs was done with Tenax followed by thermal desorption and GC-MS analysis. Results are given for single VOCs/SVOCs and for TVOC/TSVOC and show a good comparability between all four types of test housings.
