DIN CEN/TS 16201:2013-12

This Technical Specification specifies a test procedure for the determination of the content of unwanted viable weed seeds and plant propagules in growing media and soil improvers (see Annex B for validation results). The method in general is also applicable to soils and sludges. This Technical Specification is validated for compost; however, the validation results were not sufficient for publishing the method as EN standard. This Technical Specification is part of a modular horizontal approach in which this document belongs to the analytical step. The preparation of this document by CEN is based on a mandate by the European Commission (Mandate M/330), which assigned the development of standards on sampling and analytical methods for hygienic and biological parameters as well as inorganic and organic determinants, aiming to make these standards applicable to sludge, treated biowaste and soil as far as this is technically feasible. This document (CEN/TS 16201:2013) has been prepared by Technical Committee CEN/TC 400 "Project Committee - Horizontal standards in the fields of sludge, biowaste and soil", the secretariat of which is held by DIN, Germany. The responsible German committee is NA 119-01-02-04 UA "Biolologische Verfahren" ("Biological methods") of NA 119-01-02-04 AA "Abfall und Bodenuntersuchung" ("Waste and soil investigation") at the Water Practise Standards Committee (NAW) at DIN.
