O BSI 05-2001 STD-BSI BS EN 13535-ENGL 2001 = 1b24bbq 0711007 1T5 Page 3 EN 13535:2001 Introduction The classification scheme includes an explanation of the meaning of each heading and clearly assigns each fertilizer or liming material to an appropriate group whilst recognizing
17、that a few fertilizers or liming materials may be 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 descr
18、iptions, terms only and not chemical symbols to denote nutrients. This avoids ambiguity between the elemental or oxide forms 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 t
19、he definitions to be found in EN 12944. These descriptions may not necessarily correspond with those used in national legislation. 1 Scope This European Standard establishes a classification scheme for fertilizers and liming materials. 2 Normative references This European Standard incorporates by da
20、ted or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard
21、 only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments).
