This Technical Report has

23、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 Technical Reports dealing with sampling techniques and procedures, and provides essential information and instructions for the application o

24、f the EN-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 st

25、andardised 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. T

26、he Technical 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 sampli

27、ng approach, sampling point, method of sampling and equipment used. This Technical Report describes the statistical principles related to sampling, and provides methods based on these principles enabling a testing programme to be defined that will produce results sufficiently reliable for the decisi

28、on-making process for which they are required. Wastes arise in a wide variety of types (e.g. pastes, liquids, granular materials, mixes of different materials) and sampling situations (e.g. during a waste production process, stockpiles, tanks, drums). There can also be a variety of sampling objectiv

29、es within each of the three broad categories (basic characterisation, compliance testing and on-site verification). Consequently the Report cannot provide definitive instructions for each and every case on the practical details of the testing programme, such as the required number of samples, the si

30、ze of these samples, and whether they should be spot or composite samples. Instead, its aim is to expose the factors that influence the choice of these detailed components of the sampling exercise, and to provide statistical tools that can then be applied to determine the most appropriate testing pr

31、ogramme for any given sampling scenario. CEN/TR 15310-1:20065 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 heterogeneous and it will be necessary therefore

32、 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 of. In order to undertake valid tests, some sampling of t

33、he 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 and can be used to: produce standardised sampling plans for use in regular

34、or routine circumstances (elaboration of daughter/derived standards dedicated to well defined sampling scenarios); incorporate the specific sampling requirements of European and national legislation; design and develop a Sampling Plan for use on a case by case basis. The development of a Sampling Pl

35、an 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 information to support Key Step 1 of the

36、 Sampling Plan process map and describes the selection of sampling approach that can be used in the recovery of a sample for a wide variety of waste types and arisings. Specifically this Technical Report provides information to support 4.2.7 (Select sampling approach) of the Framework Standard. Due

37、consideration and selection of statistical criteria is of key importance in the production of a Sampling Plan as it provides the sole means of ensuring that, wherever possible, the type and number of samples taken will address a clearly identified objective and will provide results that achieve a to

38、lerable level of reliability.

This Technical Rep

CEN/TR 15310-1:20067 1 Scope This Technical Report discusses the statistical principles of sampling, and provides a number of statistical tools to assist in the design of testing programmes for application to sampling under var

46、ious conditions. NOTE 1 Given the great variety of waste types, sampling situations and objectives, this Technical Report cannot provide definitive instructions that cover all scenarios. Instead, it discusses the basic statistical approach to be followed, and provides statistical tools that can be a

47、pplied to determine the amount and type of sampling (e.g. number of samples and sample size) in any given situation to achieve results of adequate reliability (i.e. precision and confidence). NOTE 2 The document provides considerable detail on current best practice, but is not exhaustive. NOTE 3 To

48、clarify the text, the document provides a number of worked examples. 2 Terms and definitions For the purposes of this Technical Report, we have used or adapted the definitions of ISO 3534 Parts 1, 2 and 3 wherever possible. In a minority of cases, however, those definitions are couched in technical

49、statistical language, which is likely to be unhelpful to the intended readership. In these instances we have either supplemented the formal definition with an additional note, or provided an alternative simpler definition. NOTE In order to keep the list of definitions as compact as possible, some terms that are used only occasionally in the main text have been omitted. B.1 provides an additional list of definitions that are specifically relevant to the various annexes. 2.1 analytical erro
