Since 3 years the EN45001 standard for quality in analysis and testing is being implemented in Flanders by emission testing laboratories, as required by environmental legislation. During the implementation of the standard the officially approved laboratories were audited by the reference laboratory Vito. The audits revealed several difficulties of applying EN45001 to emission measurements. A brief summary of the frequently encountered problems is given. In the first phase problems were mainly related to non conformities with the standard which are relatively easy to correct. Some of the remaining problems deal with interpretation of the standard for the specific field of application. The solutions that were proposed by the reference laboratory are given for some of these matters, more specifically concerning the validation of methods, the recommended quality control steps and the use of calibration gases.
