Foreword
This document (CEN/TS 16675:2014) has been prepared by Technical Committee CEN/TC 292
“Characterization of waste”, 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 [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following
countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria, Croatia, Cyprus,
Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany,
Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland,
Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
Introduction
Disposal of some types of waste requires stabilisation/solidification to reduce the impact and/or comply with
regulatory requirements. The characterisation of waste is an essential step for the assessment of a potential
final destination, especially in case of landfilling and associated potential hazards. Based on its properties, a
stabilised/solidified waste material may be allocated to a landfill for granular waste or a landfill for monolithic
waste. Information on certain physical properties of a given stabilised/solidified waste material is required to
determine if it can be classified as a monolithic material and to select appropriate leaching test method(s) and
landfilling options for that waste. This technical specification describes test methods applicable to assessment
of these physical properties.
WARNING – Anyone dealing with waste and sludge analysis should be aware of the typical risks of
that kind of material irrespective of the parameter to be determined. Waste and sludge samples may
contain hazardous (e.g. toxic, reactive, flammable, infectious) substances, which can be liable to
biological and/or chemical reaction. Consequently these samples should be handled with special
care. Gases which may be produced by microbiological or chemical activity are potentially flammable
and will pressurise sealed bottles. Bursting bottles are likely to result in hazardous shrapnel, dust
and/or aerosol. National regulations should be followed with respect to all hazards associated with
the methods in this technical specification.
1 Scope
This Technical Specification provides methods, which can be used to assess the monolithic character of a
stabilised/solidified waste, with respect to landfilling. Information on the monolithic character is required to
enable the choice of appropriate leaching tests for determination of the release of different substances from
stabilised/solidified waste under specified (landfilling) conditions.
This document includes several physical and/or chemical test methods each addressing different aspects of
monolithic character. The selection of methods required for an assessment of the monolithic character of a
stabilised/solidified waste may vary, depending on the scenario to be addressed or it may be specified in
regulation.
Rather than describing the procedures and methods in detail this document refers to existing standards and
provides some guidance on their use on stabilised/solidified waste materials.
This Technical Specification does not address issues related to health and safety.
The following procedures and methods are included in this document:
— test to determine unconfined compressive strength;
— test to determine permeability;
— test to determine the loss of mass by dissolution or disintegration;
— test to determine expansion;
— test to determine the content of organic matter;
— test to determine freeze/thaw effects.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
dry matter
wdm
mass fraction of a sample excluding water expressed as a percentage by mass calculated by determination of
dry residue or water content
[SOURCE: EN 14346]
3.2
dry residue
wdr
remaining mass fraction of a sample after a drying process at 105 °C
[SOURCE: EN 14346]
3.3
eluate
solution recovered from a leaching test
3.4
laboratory sample
sample or subsample (s) sent to or received by the laboratory
[SOURCE: IUPAC:1997]
Note 1 to entry: When the laboratory sample is further prepared (reduced) by subdividing, mixing, grinding or by
combinations of these operations, the result is the test sample. When no preparation of the laboratory sample is required,
the laboratory sample is the test sample. A test portion is removed from the test sample for the performance of the test or
for analysis. 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.
Note 2 to entry: Several laboratory samples could be prepared and sent to different laboratories or to the same
laboratory for different purposes. When sent to the same laboratory, the set is generally considered as a single laboratory
sample and is documented as a single sample.
3.5
leachant
liquid used in a leaching test
[SOURCE: EN 12457–1]
3.6
leaching test
test during which a material is put into contact with a leachant and some constituents of the material are
extracted
[SOURCE: EN 12457–1]
3.7
monolithic waste
waste prepared with certain minimum dimensions and physical and mechanical properties that ensure its
integrity over a certain period of time in the considered scenario
3.8
stabilised/solidified waste
waste stabilised/solidified by chemical and physical means to form a coherent body maintaining its integrity in
the landfill over a specified timeframe.
3.9
test portion
quantity of material of proper size for measurement of the concentration or other properties of interest
removed from the test sample
[SOURCE: IUPAC:1997]
3.10
test portion of monolithic waste
specimen obtained either by moulding, by cutting or by coring and ready for the performance of a leaching
test with a minimum dimension in all directions of 40 mm
Note 1 to entry: The test portion could be taken from the laboratory sample directly if no preparation of sample is
required, but usually it is taken from the prepared test sample.
3.11
test sample
sample, prepared from the laboratory sample, from which test portions are removed for testing or analysis
[SOURCE: IUPAC:1997]
3.12
water content
ww
