This Technical Specification (CEN/TS) was approved by CEN on 28 May 2023 for provisional application.

The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.

CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

CEN members are the national standards bodies of Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia,
Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway,
Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and

European foreword
This document (CEN/TS 17943:2023) has been prepared by Technical Committee CEN/TC 444
“Environmental characterization of solid matrices”, the secretariat of which is held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the
United Kingdom.
Introduction
This document is intended to be used for the characterization of waste when information is needed to
fulfil the requirements of the Waste Framework Directive 2008/98/EC and the EC Regulation (EU)
No 1357/2014, for the classification of waste according to different hazards. This document can also be
used for the Classification Labelling and Packaging (CLP) Regulation (EC) No 1272/2008.
This document deals with the determination of elements and substances in waste to assess their hazards
if no information is available on their content.
1 Scope
This document provides guidance to the characterization of waste. It applies to all types of waste, with
unknown or partially known composition, by giving examples of EN standards dedicated to waste
characterization and analytical methods for parameters not covered by standards. Some requirements
concerning the determination of inorganic elements and organic substances content in waste are given
to achieve approximately 90 % or the highest possible mass.
In case information on the origin or on the composition of the waste is given by the owner of the waste,
it might be sufficient to follow only part of this document to complete missing knowledge about the waste.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
• ISO Online browsing platform: available at https://www.iso.org/obp
• IEC Electropedia: available at https://www.electropedia.org/
3.1
dry matter
DM
mass fraction of sample excluding water expressed as mass fraction calculated by determination of dry
residue or water content
3.2
volatile organic compounds
VOC
any organic compound having an initial boiling point less than or equal to 250 °C measured at a standard
atmospheric pressure of 101,3 kPa
Note 1 to entry: According to WHO, organic compound whose boiling point is in the range from (50 °C to 100 °C)
to (240 °C to 260 °C).
3.3
semi-volatile organic compounds
SVOC
Organic compound whose boiling point is in the range from (240 °C to 260 °C) to (380 °C to 400 °C),
according to WHO
Note 1 to entry: Boiling points of some compounds are difficult or impossible to determine because they
decompose before they boil at atmospheric pressure. Vapour pressure is another criterion for classification of
compound volatility that can be used for classification of organic chemicals. SVOCs have vapour pressure between
−2
10 mPa and 10 Pa.
3.4
unidentified volatile or semi-volatile compounds
mass calculated from the unresolved chromatographic areas of the corresponding chromatograms
3.5
non-extractable organic compounds
mass lost by calcination of the dried solid residue remaining after the extraction of semi-volatile
substances
Note 1 to entry: Chemical compound that remains un-extractable by a method which do not significantly change
the chemical nature of these residues.
3.6
internal calibration standards
compounds added in a known amount to the sample from the beginning of the protocol and enabling
analytical coverage throughout the procedure, and that is used to correct for losses during sample
preparation and analysis by accounting for all-system matrix effects (recoveries, ionization effect,
variability of the detector response of the instrument for example)
3.7
external calibration standards
compounds added in a known amount to a sample which is analysed separately from the unknown
sample under identical conditions, and used to facilitate the qualitative identification and/or quantitative
determination of the sample components
3.8
unresolved chromatographic peak
portion of a chromatogram where a separation is incomplete, and corresponding to two or more
components which may elute together from the chromatographic column
4 Principle
This method consists of determining the content of elements and substances above 0,1 % (weight) in
content of waste. It applies to laboratory samples of liquid and solid wastes. It is based on standard
methods when available, or otherwise on non-standardized methods as briefly described in this
document, specifying any extraction procedure and quantitative or semiquantitative analytical method.
All work should be led in compliance with EN 16457. Sampling should be performed in compliance with
EN 14899 and with guidance documents CEN/TR 15310-1 to 5. Laboratory samples should be prepared
according to EN 15002. All standards to which this document refers to are listed in Table 1.
