In Regulation (EC) No. 2003\/2003 [2] tolerance limits are mentioned for nutrient contents in mineral fertilizers (Annex II of Regulation (EC) No. 2003\/2003) as well as prescribed methods for control purposes (Annex IV of Regulation (EC) No. 2003\/2003).<\/p>\n

Prior to the work done by CEN\/TC 260 following Mandate M\/335, no statistical data were available for the official analytical methods to be applied. Due to the standardization work done for this mandate, statistical data have been generated as ring testing was a major topic in this mandate.<\/p>\n

This Technical Specification describes to what extent the presently applied tolerances are in line with the obtained precision data from the analytical methods studied.<\/p>\n

The purpose of this document is to give feedback on the applied tolerances within Regulation (EC) No. 2003\/2003 based on the method evaluation done as an outcome of the work executed by CEN\/TC 260\/WG 7 according to Mandate M\/335. This evaluation of the tolerances was part of Mandate M\/418.<\/p>\n
