scope:

Development of technical principles, which will be used across the board for future standardization projects on testing methods for plastics and microplastics in various matrices (in particular water, soil, compost, sewage sludge, biota). This includes the following:: - Description of necessary working conditions in the laboratory - Description of necessary working conditions in the field - safety instructions - Proposals for harmonisation of size classes to be considered - Proposals to harmonise the indication of results - Notes on matrix-specific particularities with regard to the representativeness of the results
