21、EN 1482-3:2016EN 1482-3:2016 (E) 4 Introduction The establishment of European Standards for methods of sampling and analysis is of utmost importance to guarantee a uniform application and control of the European legislation in all Member States. Standardized methods of sampling and analysis are esse

22、ntial 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 term “EC fertilizer” Member States are required to check the nutrient content of such fertilizers. To achieve this, representative sampling is

23、essential for reliable analytical results. Competent authorities have limited resources for conformity assessment and these are most efficiently deployed at the downstream end of the supply chain. The purpose of Regulation (EC) No 2003/2003 1 is to ensure that the fertilizer meets European requireme

24、nts 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 needs of Member States when a large quantity of fertilizer is stored in a static heap that cannot be realistically put into motion. An evaluat

25、ion 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). The fundamental principle of representative sampling is that every particle has an equal chance of being sampled. This principle cannot easily

26、 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 device. Wherever possible, this fertilizer should be sampled during transfer, during the building up of the heap, during dispatch or where it ca

27、n practically be moved solely for sampling purposes. However, in some cases, sampling in the way described is not practicable. The European Commission asked CEN/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

28、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. In response to the mandate, sampling methods to sample static heaps have been developed and standardized as specified in this document. BS EN

29、 1482-3:2016EN 1482-3:2016 (E) 5 1 Scope This European Standard is applicable to the sampling of mineral fertilizers and liming materials supplied or ready 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 Europ

30、ean 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 samples from static bulk heaps in order to ascertain compliance with legal requirements, in particular in relation to the accuracy of compulsory or p

31、ermitted statutory declarations. The methods specified in this document are not applicable to obtain samples for physical analysis or for the chemical analysis which may be altered by particle granulometric segregation. This European Standard is applicable to single nutrient fertilizers, to uniform

32、complex fertilizers and to milled or granulated liming materials. The methods described in this document are not suitable for sampling other types of fertilizer, for example blended fertilizers. NOTE The term fertilizer is used throughout the body of this European Standard and includes liming materi

33、als unless otherwise indicated. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenc

34、ed document (including any amendments) applies.

The methods to be used for sampling static heaps are specified in the following clauses. BS EN 1482-3:2016EN 1482-3:2016 (E)

37、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 to be sampled shall be undertaken. In particular, the following physical characteristics shall be noted: kind/type, texture, colour, storage conditio

38、ns, e.g. uncovered/covered, foreign matters. If the owner of the material is applying the same description and statutory information to the whole lot, sampling should proceed in accordance with this document. Only if there is evidence of deterioration or contamination should consideration be given t

39、o 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 after the characteristics according to 4.2 have been considered. Any variations from the stated sampling plan shall be documented in written form. T

40、he sampling plan shall define the course of the sampling process, and associated provisions, in reproducible manner. Sampling only around the base of the 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

41、following elements shall be stated: boundary of the lot, determination of the volume/mass of the lot, determination of the number and location of sampling units, determination of sampling units from which the increments shall be taken, if necessary, preparation of a sketch-map of the sampling areas

42、(see Figure 1), determination of the minimum number of sampling points from which sub-samples are to be taken to form the incremental sample, determination of minimum volume/mass of increments.

Sub-samples shall comprise of a quantity of material taken at randomly selected points in each selected sampling unit. These shall be mixed to form the in
