Characterization of waste - Preparation of test portions from the laboratory sample

This European Standard is applicable for the preparation of representative test portions from the laboratory sample that has been taken according to the sampling plan (EN 14899), prior to physical and/or chemical analysis (e.g. preparation of eluates, extractions, digestion and/or analytical determinations) of solid (including monolithic material) and liquid samples and sludge. It is also applicable for the preparation of test portions from digests and eluates for the subsequent analyses.
This European Standard is intended to find the correct sequence of operations and treatments to be applied to the laboratory sample in order to obtain suitable test portions in compliance with the specific requirements defined in the corresponding analytical procedures.

Overview - EN 15002:2015 (Characterization of waste)

EN 15002:2015 is a CEN European Standard that specifies how to prepare representative test portions from a laboratory sample taken according to a sampling plan (e.g., EN 14899) before physical or chemical analysis. It covers solid (including monolithic materials), liquid samples and sludge, and it also applies to preparing test portions from digests and eluates used for subsequent analytical determinations. The standard defines the correct sequence of operations and treatments so test portions comply with analytical procedure requirements and maintain representativity.

Key topics and technical requirements

• Sequence of treatment techniques - EN 15002 emphasizes choosing the correct order of operations to avoid analyte loss or contamination.
• Homogenization - methods for making samples uniform (different approaches for solids, liquids and volatile compounds).
• Phase / fraction separation - when homogenization is impractical; includes solid–liquid and liquid–liquid separation and fractioning of solids.
• Drying and particle size reduction - guidance on removing interfering water and on milling / crushing, with re-homogenization to prevent segregation.
• Sub-sampling and test portioning - procedures (manual and mechanical) for obtaining representative sub-samples and test portions, including monolithic sample cutting/coring.
• Equipment and contamination control - selection of compatible materials, cleaning to avoid abrasion, cross-contamination and chemical release; recommended dedicated rooms for crushing/sieving.
• Interferences, sources of error and safety - awareness of volatile losses, dust, gas pressure in sealed containers, and hazardous constituents in wastes; follow national safety rules.
• Documentation and reporting - record the sequence of treatment steps and any deviations so analytical results remain traceable.

Applications and who uses it

EN 15002:2015 is used by:

• Environmental and waste testing laboratories preparing samples for chemical and physical analyses
• Regulatory agencies and compliance laboratories conducting waste characterization
• Environmental consultants and waste management companies verifying waste composition
• Research institutions working on sludge, contaminated soils, or monolithic waste materials

Practical applications include preparation for eluate testing, chemical digestion, extraction, volatile and semi-volatile organic compound analysis, and metal determinations where representative subsamples are critical for reliable results.

Related standards

• EN 14899 - Guidance on sampling and the sampling plan for waste characterization
• EN 12457-1:2002 - Definitions and test methods referenced for wastes (granular waste)
• ISO 13877, ISO 10382, ISO 10381-7 - referenced for organic/volatile compound definitions and methods

EN 15002:2015 ensures that laboratory sample preparation is systematic, reproducible and suitable for accurate analytical determinations in waste characterization.

Guideline for choosing sample treatment techniques A.1 General The preparation of test samples from a laboratory sample will frequently involve a sequence of operations such as homogenization, phase separation, drying, particle size reduction and sub-sampling. Specific forms of these operations are described in this annex. The sample treatment techniques prescribed in the analytical standards shall be fulfilled in any case. In case of monolithic waste, the laboratory sample may consist of one or several monoliths. This implies that some of the sample treatment techniques common for granular waste may not be necessary depending on the requirements of the relevant analytical method. A.2 Homogenization A.2.1 General information Before each operation that implies (sub)-sampling (with the exception of monolithic test portions), a homogenization step is required, in order to guarantee that all (sub)-samples or sample fractions have the same properties and composition. The homogenization technique to be used is chosen depending on the properties of the sample. In many cases before homogenization particle size reduction may be necessary. Incorrectly executed homogenization can increase the heterogeneity of the sample by segregating particles of different density or grain size. Particle size reduction prior homogenization reduces the risks of segregation in the homogenization process. If homogenization of a sample is too difficult or even practically impossible (e.g. if the sample contains pieces of plastic or metal), its phases shall be separated and treated as if they were different samples (see A.3). A.2.2 Solid samples A.2.2.1 Manual homogenization When to use it: — generally usable; — in cases when mechanical homogenization could lead to loss of volatile compounds of interest. When not to use it: — for samples that segregate because of the presence of particles of different size or density; — for samples with particles of such a large size that homogenization cannot be reached by manual mixing.
