Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Engineered stone — Vocabulary
1 Scope
This document specifies terms and definitions of engineered stone intended for use in finished products
such as countertops and vanities, floor and wall coverings and accessories including its raw materials,
manufacturing, fabrication and installation.
2 Normative references
There are no normative references in this document.
3 Terms and definitions
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 Definition of engineered stone
3.1.1
engineered stone
composite material manufactured from a mixture of aggregates, binders and additives intended for
fabrication of countertops and vanities, floor and wall coverings and ancillary uses, for both interior and
exterior applications
Note 1 to entry: Engineered stone has also been known as artificial marble, artificial stone, manufactured stone,
agglomerated stone, engineered quartz, quartz, quartz surfacing etc.
3.2 Classifications and definitions of engineered stone products
3.2.1
classification according to the mineral nature of the aggregates
engineered stone product can be classified as calcareous nature, siliceous nature or a combination of the
two
3.2.2
classification according to the type of the binder
engineered stone product can be classified as resin, hydraulic cement or mixtures of resin and cement
3.2.3
engineered stone cut to size product
finished product obtained from a rough slab or a slab, the dimensions of which must be referred to a template
or a drawing
[SOURCE: EN 16954:2018, 3.3, modified — “engineered stone” added in the term, "need to be" changed to
"must", “agglomerated” deleted from the definition, Note 1 to entry deleted]

3.2.4
engineered stone panel
finished product with thickness ≤5,5 mm, surface area >1 m , and any edge length > 1 200 mm or an
engineered stone tile declared as a thin engineered stone panel by its manufacturer or having properties
meeting an international or national standard for thin engineered stone panels
[SOURCE: ISO/TR 17870-2:2015, 3.1.3, modified — “thin ceramic” replaced with “engineered stone” in the
term and the definition]
3.2.5
engineered stone rough slab
semi-finished engineered stone product with edges obtained either by sawing from a block or by moulding
the surface of which may or may not be the finished surface
Note 1 to entry: The size is given by nominal dimensions in this order: length, width, thickness expressed in
millimetres.
[SOURCE: EN 16954:2018, 3.1, modified — “engineered stone” added in the term, “agglomerated” replaced
by “engineered” in the definition, “the size is given by nominal dimensions in this order: length, width,
thickness expressed in millimetres” moved to the Note 1 to entry]
3.2.6
engineered stone slab
finished product obtained from rough slabs, the surface of which is a finished surface ready to use
Note 1 to entry: The dimensions of which are given by length - width - thickness (in this order), expressed in
millimetres according to defined tolerances.
[SOURCE: EN 16954:2018, 3.2, modified — “engineered stone” added in the term, “agglomerated” deleted
from the definition, “the dimensions of which are given by length - width - thickness (in this order), expressed
in millimetres according to defined tolerances” moved to the Note 1 to entry]
3.2.7
engineered stone tile
element made from engineered stone and used as covering for floors and walls
Note 1 to entry: Engineered stone generally consists of an area less than or equal to 1 m and up to 30 mm thick.
3.3 Terms and definitions of sourced raw materials
3.3.1
indigenous raw material
raw material that is recovered, harvested, or extracted within an 800 km radius of the manufacturing site
Note 1 to entry: Where materials are transported by water or rail, the distance to the manufacturing site shall be
determined by multiplying the distance that the materials are transported by water or rail by 0,25 and adding that
number to the distance transported by means other than water or rail.
3.3.2
post-consumer material
waste material generated by households or by commercial, industrial and institutional facilities in their role
as end-users of the product, which can no longer be used for its original intended purpose
3.3.3
pre-consumer material
material, solid and/or liquid, diverted from a waste stream generated by the manufacturing process
Note 1 to entry: Reutilization of materials (i.e. rework, regrind or scrap generated in a process that does not enter the
waste stream and that is capable of being reclaimed within the same process
