Engrais et amendements minéraux basiques - Echantillonnage et préparation de l'échantillon - Partie 2: Préparation de l'échantillon
La présente Norme européenne spécifie des méthodes de réduction et de préparation des échantillons d’engrais et amendements minéraux basiques et établit les exigences relatives aux rapports d’échantillonnage. Elle spécifie également des méthodes de préparation d’échantillons d’essai et de prises d’essai issues d’échantillons de laboratoire des engrais en vue d’une analyse physique ou chimique ultérieure. La présente norme ne couvre pas la préparation d’échantillons destinés a certains essais physiques nécessitant l’obtention de prises d’essai d’une masse supérieure a 2 kg. Elle s’applique a tous les engrais.
NOTE Le terme « engrais » est utilisé tout au long du présent document et il convient de le considérer comme incluant les amendements minéraux basiques, sauf indication contraire.

EN 1482-2:2007 (E) 3 Foreword This document (EN 1482-2:2007) 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of an identical text or by endorsement, at the latest by July 2007, and conflicting national standards shall be withdrawn at the latest by July 2007. Together with Part 1, this document supersedes EN 1482:1996. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association to provide a means of conforming to Essential Requirements of the Regulation (EC) No 2003/2003 of the European Parliament and of the Council of 13 October 2003 relating to fertilizers. EN 1482, Fertilizers and liming materials — Sampling and sample preparation” consists of two parts: Part 1: Sampling Part 2: Sample preparation 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, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
EN 1482-2:2007 (E) 4 Introduction This European Standard (EN 1482-2) covers the following aspects of sample preparation, derived from the International Standards and documents indicated but presented in a simplified and condensed form. The titles of the International Standards are given in the Bibliography. Reduction and preparation of samples for analysis: ISO 7410, ISO 7742, ISO 8358 and EEC 77/535 (superseded by Regulation (EC) No 2003/2003); Sampling reports: ISO 5306 and EEC 77/535 (superseded by Regulation (EC) No 2003/2003). EN 1482-1 covers the sampling of fertilizers and liming materials. Figure 1 gives a schematic diagram of the sampling and sample preparation process for solids.

For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 1482-1:2007, Fertilizers and liming materials — Sampling and sample preparation — Part 1: Sampling ISO 3310-1, Test sieves — Technical requirements and testing — Part 1: Test sieves of metal wire cloth 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 division process of producing a number of representative smaller portions, approximately equal in mass to each other, from a larger mass 3.2 final sample representative part of the reduced sample or, where no intermediate reduction is required, of the aggregate sample NOTE Often, more than one sample is prepared, at the same time, from the reduced sample (or from the aggregate sample). One or more of these final samples is used as a laboratory sample or as laboratory samples, while others may be stored for reference purposes. 3.3 laboratory sample final sample intended for laboratory inspection or testing 3.4 reduction process of producing a representative smaller mass of fertilizer from a larger mass, with the remainder being discarded 3.5 test portion quantity of material taken from the test sample (or if both are the same, from the laboratory sample) and on which the test or observation is actually carried out 3.6 test sample sample prepared from the laboratory sample and from which test portions are taken
EN 1482-2:2007 (E) 7 4 Principle Reduction and division of the laboratory sample, as necessary, to produce test samples. Preparation of test portions from the test samples by division, with or without previous grinding, or by combination, as appropriate. 5 Apparatus 5.1 General Apparatus used in the preparation and storage of samples shall be clean and dry and made from materials which will not affect the characteristics of the fertilizer. 5.2 Rotary sample divider, conforming to the requirements specified in EN 1482-1:2007, 5.6.3, or riffle divider conforming to the requirements specified in EN 1482-1:2007, 5.7.2. 5.3 Sample grinder, capable of taking the whole sample at one pass and, preferably, totally enclosed. It shall have a screen, or other mechanism without a screen, which allows the ground material to pass through the machine into a collecting vessel and away from the cutters or grinding discs, to avoid over-grinding. In the case of a grinder with screens, the fineness of grind can be adjusted by the fitting of different mesh screens. Grinding shall continue until as much as possible of the fertilizer has passed through the machine. NOTE If the grinder is of the open type, the moisture content of the fertilizer can change significantly during grinding. Any machine used for grinding samples as required by this European Standard shall be checked for satisfactory performance. Particular points to be checked are: a) the fineness of grinding achieved; b) the temperature rise of the material being ground (see 6.3); c) non-contamination of the sample. 5.4 Mortar and pestle, of suitable material and size. 5.5 Test sieves, conforming to ISO 3310-1 of nominal aperture sizes 1,0 mm, 0,5 mm and 0,18 mm.
