T

15、his Technical Report has been prepared under a mandate given to CEN by the 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

16、-standard: EN 14899, Characterisation of waste - Sampling of waste materials - 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 standard

17、ised 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 basis. The Tec

18、hnical Reports display a range of potential approaches and tools to enable 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 app

19、roach, sampling point, method of sampling and equipment used. This Technical Report describes a range of techniques that could be used to sample a range of waste types from a variety of locations and arisings. Information is also provided on the selection and preparation of equipment and apparatus n

20、eeded to complete the sampling exercise. This report does not 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 practica

21、l field activities to ensure the most appropriate procedure 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 barri

22、er to technical innovation, and there is no reason why methodologies other than those detailed in this Technical Report cannot be substituted. CEN/TR 15310-2:20064 Introduction Wastes are materials, which the holder discards, or intends or is required to discard, and which may be sent for final disp

23、osal, reuse or recovery. Such materials are generally heterogeneous 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 shoul

24、d be treated (or not), recovered or disposed. In order to 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 Fi

25、gure 1 of EN 14899:2005. This standard can be used to: produce 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 legislati

26、on; design and develop a Sampling Plan on a case by case basis. 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 sam

27、ple to the laboratory This Technical Report provides information to support Key Step 2 of the Sampling Plan process map and describes a selection of sampling techniques that can be used in the recovery of a sample for a wide variety of waste types and arisings. The sampling technique is the physical

28、 procedure employed by the sampler to collect part or parts of a discarded or secondary material for subsequent investigations. Specifically this Technical Report provides information to support 4.2.8.1 (Identify the sampling technique) of the Framework Standard. This Technical Report should be read

29、 in conjunction with the Framework Standard for the preparation and application of a Sampling Plan as well as the other Technical Reports that contain essential information to support the Framework Standard. The full series comprises: EN 14899, Characterization of waste - Sampling of waste materials

32、, storage, preservation, transport and delivery; CEN/TR 15310-5, Characterization of waste Sampling of waste materials Part 5: Guidance on the process of defining the Sampling Plan. The Technical Reports contain procedural options (as detailed in Figure 2 of EN 14899:2005) that can be selected to ma

33、tch the sampling requirements of any testing programme. CEN/TR 15310-2:20065 1 Scope This Technical Report describes techniques for sampling liquid and granular waste material, including paste-like materials and sludges, found in a variety of locations. The Technical Report provides information to a

34、llow the selection and preparation of equipment and apparatus to be used in the sampling activity. NOTE 1 This Technical Report provides a shop shelf of example sampling techniques that can be selected to meet a wide range of sampling situations. For a specific situation one of the presented procedu

35、res 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 referenced documents are indispensable for the application of this document.

43、material may be homogeneous with respect to one analyte or property but heterogeneous with respect to another. NOTE 2 The degree of heterogeneity (the inverse of homogeneity) is the determining factor in sampling error. 3.10 homogeneity degree to which a property or a constituent is uniformly distri

ISO 11074 3.11 increment individual portion of material collected by a single operation of a sampling device NOTE 1 Increments may be reduced and tested individually or combined with other increments, with the resulting composite reduced in size and tested as

45、 a single unit. NOTE 2 Increments are created by the sampling operation and are usually taken from parts of a lot separated in time or space. 3.12 judgemental sampling sampling undertaken from a practically convenient (perhaps relatively small) sub-population, not conducted fully in accordance with

When

47、 no preparation of the laboratory sample is required, the laboratory sample is the test sample. CEN/TR 15310-2:20067 NOTE 2 The laboratory sample is the final sample from the point of view of sample collection but it is the initial sample from the point of view of the laboratory.
