| BSI | 2024 | 149 |
This document specifies the general performance criteria and test procedures for the performance test of portable automated measuring systems (P-AMS) used for periodic measurements of stationary source emissions. It applies to the performance test of P-AMS based on measurement techniques specified by the standard reference method (SRM) or an alternative method (AM). The performance test is based on the general performance criteria and test procedures specified in this document and on the specific requirements specified for the SRM or AM. This includes testing of the applicability and correct implementation of the QA/QC procedures specified for the SRM or AM. This document supports the requirements of particular EU Directives.
