DIN EN 1482-3:2016-10EN 1482-3:2016 (E) 4 Introduction The establishment of European Standards for methods of sampling and analysis is of utmost importance to guarante
23、e a uniform application and control of the European legislation in all Member States. Standardized methods of sampling and analysis are essential elements in guaranteeing a high level of quality and safety of EC fertilizers for the benefit of purchasers. In order to avoid any improper use of the ter
24、m “EC fertilizer” Member States are required to check the nutrient content of such fertilizers. To achieve this, representative sampling is essential for reliable analytical results. Competent authorities have limited resources for conformity assessment and these are most efficiently deployed at the
25、 downstream end of the supply chain. The purpose of Regulation (EC) No 2003/2003 1 is to ensure that the fertilizer meets European requirements and complies with the declaration of the required characteristics applied to it when delivered to a purchaser. EN 1482-1:2007 might not fully satisfy the ne
26、eds of Member States when a large quantity of fertilizer is stored in a static heap that cannot be realistically put into motion. An evaluation was requested to be carried out by CEN to see what, if any, static heaps of fertilizer could be representatively sampled at affordable costs see (see 3). Th
27、e fundamental principle of representative sampling is that every particle has an equal chance of being sampled. This principle cannot easily be complied with in the case of bulk static heaps of solid fertilizers as a large proportion of the material cannot practically be reached by any sampling devi
28、ce. Wherever possible, this fertilizer should be sampled during transfer, during the building up of the heap, during dispatch or where it can practically be moved solely for sampling purposes. However, in some cases, sampling in the way described is not practicable. The European Commission asked CEN
29、/TC 260/WG 1 to draft a European Standard in response to mandate M/454, which requires the development of a method of sampling static heaps that could not be sampled according to EN 1482-1:2007. This states that the sampling of static heaps should only be carried out when the product is in motion. I
30、n response to the mandate, sampling methods to sample static heaps have been developed and standardized as specified in this document. DIN EN 1482-3:2016-10EN 1482-3:2016 (E) 5 1 Scope This European Standard is applicable to the sampling of mineral fertilizers and liming materials supplied or ready
31、for supply to third parties, as a lot or in smaller lots, where such supply or readiness for supply is subject to legal requirements. This European Standard specifies plans and methods of sampling of a lot of solid fertilizer or liming material, if sampling in motion is not possible, to obtain sampl
32、es from static bulk heaps in order to ascertain compliance with legal requirements, in particular in relation to the accuracy of compulsory or permitted statutory declarations. The methods specified in this document are not applicable to obtain samples for physical analysis or for the chemical analy
33、sis which may be altered by particle granulometric segregation. This European Standard is applicable to single nutrient fertilizers, to uniform complex fertilizers and to milled or granulated liming materials. The methods described in this document are not suitable for sampling other types of fertil
34、izer, for example blended fertilizers. NOTE The term fertilizer is used throughout the body of this European Standard and includes liming materials unless otherwise indicated. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are ind
35、ispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

36、s and definitions For the purposes of this document, the terms and definitions given in EN 1482-1:2007 and the following apply. 3.1 fertilizer solid inorganic material designated for use as a fertilizer including liming materials 3.2 sampling point point in the sampling unit from which a sub-sample
37、is taken Note 1 to entry: For the definition of sub-sample, see EN 14821:2007, Note in 3.5. 3.3 static heap quantity of fertilizer stored in bulk in a single mass 4 Sampling plans and quantitative data 4.1 General The objective of sampling is to acquire a sample of the lot to establish its compositi
38、on and properties. The methods to be used for sampling static heaps are specified in the following clauses. DIN EN 1482-3:2016-10EN 1482-3:2016 (E) 6 4.2 Characterization of the lot to be sampled Before a sampling plan is determined, a description of the characteristics of the lot that is intended t
39、o be sampled shall be undertaken. In particular, the following physical characteristics shall be noted: kind/type, texture, colour, storage conditions, e.g. uncovered/covered, foreign matters. If the owner of the material is applying the same description and statutory information to the whole lot, s
40、ampling should proceed in accordance with this document. Only if there is evidence of deterioration or contamination should consideration be given to the dividing of the lot into parts from which separate samples should be taken. 4.3 Sampling plan 4.3.1 General The sampling plan shall be determined
41、after the characteristics according to 4.2 have been considered. Any variations from the stated sampling plan shall be documented in written form. The sampling plan shall define the course of the sampling process, and associated provisions, in reproducible manner. Sampling only around the base of th
42、e heap or from a single part of the heap does not supply a representative sample. 4.3.2 Elements of the sampling plan Within the sampling plan, the following elements shall be stated: boundary of the lot, determination of the volume/mass of the lot, determination of the number and location of sampli
43、ng units, determination of sampling units from which the increments shall be taken, if necessary, preparation of a sketch-map of the sampling areas (see Figure 1), determination of the minimum number of sampling points from which sub-samples are to be taken to form the incremental sample, determinat
44、ion of minimum volume/mass of increments.
