Foreword
This Technical Report (CEN/TR 15310-3:2006) has been prepared by Technical Committee CEN/TC 292
“Characterization of waste”, the secretariat of which is held by NEN.
This 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-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 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 basis.
The 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 sampling approach,
sampling point, method of sampling and equipment used.
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 prior to analysis.
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 practical 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 barrier to technical innovation, and there is no reason why methodologies other than those detailed
in this Technical Report cannot be substituted.
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 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 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:
 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 legislation;
 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 sample to the laboratory.
This Technical Report provides information 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 analytical 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 prior 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 representative 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 the other Technical Reports that contain essential information to
support the Framework Standard. The full series comprises:
