Emission classification and labels

A number of emission classification systems changed the test method and/or the classification values, like DIBT, EMICODE, and GuT. New classifications were born, e.g. Natureplus. Harmonisation of the testing protocols showed some progress. But there is also a trend to define limits for SVOC and for single substances. Not all of these parameters can be monitored with sufficient reliability. Identification of complex mixtures is done in a very different manner from lab to lab. This applies especially to terpenes and hydrocarbon mixtures. The GEV round robin test 2003 showed that some laboratories still are facing severe problems with identification and proper quantification.
