EN 16962:2018 (E) 3 European foreword This document (EN 16962:2018) has been prepared by Technical Committee CEN/TC 260 “Fertilizers and liming materials”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by July 2018, and conflicting national standards shall be withdrawn at the latest by July 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 16962:2018 (E) 4 Introduction The preparation of this document is based on a mandate given to CEN by the European Commission and the European Free Trade Association (Mandate M/335) concerning the modernization of methods of analysis of fertilizers in the framework of Regulation (EC) No 2003/2003 [1]. Water extraction is empirical and in many cases cannot be quantitative. The extraction is dependent on temperature and extraction time, on the ratio of water/sample and intensity of the extraction. To reduce the level of uncertainty of the extraction step to a reasonable level it is necessary to strictly follow the given procedure. The method can be applied to mineral fertilizers with micro-nutrient content of

10 % as well as of > 10 %. Removal of organic compounds is not usually necessary if FAAS or ICP-AES method of determination is used. It is applied only in some cases for determination of boron and molybdenum by spectrophotometric methods, determination of boron by acidimetric titration and gravimetric determination of molybdenum. The method for removal of organic compounds is a part of this standard. WARNING — Persons using this European Standard should be familiar with normal laboratory practice. This European Standard does not purport to address all of the safety issues, if any, associated with its use. It is the responsibility of the user to establish appropriate health and safety practices and to ensure compliance with any national regulatory conditions. IMPORTANT — It is absolutely essential that tests conducted according to this European Standard are carried out by suitably trained staff. SIST EN 16962:2018
