Page 3EN 13535:2001IntroductionThe classification scheme includes an explanation of the meaning of each heading and clearly assigns eachfertilizer or liming material to an appropriate group whilst recognizing that a few fertilizers or liming materials maybe classified differently in some countries.The limits for nutrient contents which determine each class can be subject to national legislation.Owing to historical and legislative differences between countries, this European Standard uses, in the descriptions,terms only and not chemical symbols to denote nutrients. This avoids ambiguity between the elemental or oxideforms and leaves each country free to declare nutrient contents according to national requirements.The descriptions given in clause 4 are not definitions but are given to explain the definitions to be found in EN12944. These descriptions may not necessarily correspond with those used in national legislation.1 ScopeThis European Standard establishes a classification scheme for fertilizers and liming materials.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies (including amendments).EN 12944 (all parts), Fertilizers and liming materials - Vocabulary.3 Terms and definitionsFor the purposes of this European Standard, the terms and definitions given in EN 12944 apply.4 ClassificationNOTEThe classification scheme is shown in figure 1.4.1 Inorganic fertilizers and liming materials4.1.1 Inorganic fertilizers : Fertilizers added to the soil especially for the nutrition of plants and in which thedeclared nutrients are in the form of inorganic salts obtained by extraction and/or by physical and/or chemicalindustrial processes.NOTECalcium cyanamide, urea and its condensation and association products and bone superphosphate may, byconvention, be classed as inorganic fertilizers.4.1.1.1 N, P, K fertilizers4.1.1.1.1 Straight N, P, K fertilizers4.1.1.1.1.1Straight nitrogenous fertilizers (N) : Fertilizers which have a declarable nitrogen content andwhich may contain other elements, but which do not have declarable phosphorus and/or potassium contents.SIST EN 13535:2002
