Abstract

Series: European Collaborative Action - Indoor Air Quality & Its Impact On Man (EAC-IAQ)

Eighteen laboratories from 10 European countries participated in a comparison organised in the frame of the project VOCEM, a 2.5 year research collaboration among 4 research institutes and 4 industrial companies. The VOCEM project ("Further development and validation test chamber method for measuring VOC emissions from building materials and products") has been partially funded by the European Commission (Contract no. SMT4-VT95-2039). The scope of the project was to improvise the procedure used to measure VOC emitted from building materials and products in small test chambers. The inter-laboratory comparison included the GC-MS determination of 5 target compounds from carpet, 8 from PVC cushion vinyl and 2 from paint; for the first time, chamber recovery (sinks), homogeneity of solid materials and possible contamination during transport were tested. The results show that the intra-laboratory variance (random errors) is much smaller than the inter-laboratory variance (systematic errors). Causes of the largest inter-laboratory discrepancies were: (a) losses of the heaviest compounds due to sorption on the chamber walls; (b) non homogeneity of the materials. The output of this work concerns both the objective of labelling materials with regard to their VOC emissions and the pre-standard drafted by CEN for this type of determination.
