This Technical Report has been prepared under a mandate given to CEN by t
13、he European Commission and the European Free Trade Association. This Technical Report is one of a series of five, dealing with sampling techniques and procedures, which provide essential information for the application of the EN-Standard: EN 14899 Characterisation of waste - Sampling of waste materi
14、als - Framework for the preparation and application of a Sampling Plan The principal component of the EN Standard is the mandatory requirement to prepare a Sampling Plan. This EN 14899 standard can be used to: produce standardised sampling plans for use in regular or routine circumstances (i.e. the
15、elaboration of daughter/derived standards dedicated to well defined sampling scenarios); incorporate specific sampling requirements into national legislation; design and develop a Sampling Plan on a case by case basis. The Technical Reports display a range of potential approaches and tools to enable
16、 the project manager to tailor his sampling plan to a specific testing scenario (i.e. a shop shelf approach to sampling plan development for waste testing). This approach allows flexibility in the selection of the sampling approach, sampling point, method of sampling and equipment used. This Technic
17、al Report describes procedures for reducing the overall size of the sample in the field, to aid practical transportation of a sample to the laboratory. It does not deal with sub-sampling in the laboratory to provide a test portion or the pre-treatment of samples prior to analysis. This report does n
18、ot attempt to provide a definitive procedure for each and every situation that may arise from sampling a given waste type or specific analytical requirement, rather it aims to expose the factors that influence the selection of these practical field activities to ensure the most appropriate procedure
19、 is selected for any given sampling scenario. The most appropriate approach, tools, and methodology, in the absence of an existing recognised Sampling Plan, should be chosen on a scenario-specific basis. However, this does not present a barrier to technical innovation, and there is no reason why met
20、hodologies other than those detailed in this Technical Report cannot be substituted. CEN/TR 15310-3:20064 Introduction Wastes are materials, which the holder discards, or intends or is required to discard, and which may be sent for final disposal, reuse or recovery. Such materials are generally hete
21、rogeneous and it will be necessary therefore to specify in the testing programme the amount of material for which the characteristics of interest need to be defined. The testing of wastes allows informed decisions to be made on how they should be treated (or not), recovered or disposed. In order to
22、undertake valid tests, some sampling of the waste is required. The principal component of the standard EN 14899 is the mandatory requirement to prepare a Sampling Plan, within the framework of an overall testing programme as illustrated in Figure 1 of EN 14899:2005. This standard can be used to: pro
23、duce standardised sampling plans for use in regular or routine circumstances (i.e. the elaboration of daughter/derived standards dedicated to well defined sampling scenarios); incorporate specific sampling requirements into national legislation; design and develop a Sampling Plan on a case by case b
24、asis. The development of a Sampling Plan within this framework involves the progression through three steps or activities. 1) Define the Sampling Plan; 2) Take a field sample in accordance with the Sampling Plan; 3) Transport the laboratory sample to the laboratory. This Technical Report provides in
25、formation to support Key Step 2 of the Sampling Plan process map and elaborates on the range of potential approaches that can be used to reduce the size of a sample in the field to facilitate the appropriate storage and preservation of the sample and ultimately its transportation to the designated a
26、nalytical facility. This Technical report describes procedures for reducing the overall size of the sample in the field, to aid practical transportation of a sample to the laboratory. It does not deal with sub-sampling in the laboratory to provide a test portion, or the pre-treatment of samples prio
27、r to analysis. Samples dispatched to the laboratory may require additional sub-sampling and/or pre-treatment steps prior to analysis. Some samples may be analysed without additional treatment. Field sub-sampling should be carried out in such a way as to obtain, at all stages, a sample that is repres
28、entative of the field sample. Specifically this Technical Report supports 4.2.8.2 (Procedures for sub-sampling in the field) of the Framework Standard. This Technical Report should be read in conjunction with the Framework Standard for the preparation and application of a Sampling Plan as well as th
29、e other Technical Reports that contain essential information to support the Framework Standard.

NOTE 1 This Technical Report provides a shop shelf of example sampling techniques that can be selected to meet a wide range o
34、f sampling situations. For a specific situation one of the presented procedures may be appropriate. NOTE 2 The procedures listed in this Technical Report reflect current best practice, but these are not exhaustive and other procedures may be equally relevant. 2 Normative references The following ref

39、other increments in a composite sample NOTE 1 Whenever the portion of material collected by a single operation of a sampling device is analysed individually, the obtained material is called a sample. In such a situation it is essential that the quantity of material fulfils both the criteria for the
40、size of an increment as well as for a sample. NOTE 2 In some languages the term increment is used without the condition that an increment will never be analysed on its own. For this Technical Report this is however an essential condition in the definition of the term increment. CEN/TR 15310-3:20067
