EN 12944-3:2001 (E)2ForewordThis European Standard has been prepared by CEN/TC 260 "Fertilizers and liming materials", the secretariat ofwhich is held by DIN.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by May 2002, and conflicting national standards shall be withdrawn at the latest byMay 2002.This European standard is in three parts: Part 1:General terms. Part 2:Terms relating to fertilizers. Part 3:Terms relating to liming materials.These definitions may not necessarily correspond with those used in national legislation.NOTEA classification scheme for fertilizers and liming materials is given in EN 13535.The annexes A and B are informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,Switzerland and the United Kingdom.SIST EN 12944-3:2002
