European foreword
This document (prEN 17903:2023) has been prepared by Technical Committee CEN/TC 134 “Resilient,
textile, laminate and modular mechanical locked floor coverings”, the secretariat of which is held by NBN.
This document is currently submitted to the CEN Enquiry.

Introduction
Answering a need to develop a circular economy for floor covering products, this document is intended
to allow producers and consumers to exchange information on the use and content of recycled, bio-based
and renewable materials in textile floor coverings. Where necessary, a distinction is made between
organic and inorganic materials. The standard provides a clear systematic definition and reporting
format to allow a transparent information exchange between producers, consumers and the recycling
industry.

1 Scope
This document establishes definitions related to the use of organic and inorganic recyclates, bio-based
and natural (animal- or plant-based) materials in textile floor coverings and defines calculation and
reporting methods for the transparent and consistent declaration thereof.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 1307, ISO 472, ISO 2424 and the
following apply.
3.1
textile floor covering with pile / pile textile floor covering
floor covering having a textile use-surface formed from a layer of yarns or fibres projecting from a
substrate
3.2
textile floor covering without pile
floor covering composed of a non-pile textile use-surface, with or without a substrate
3.3
unit area
default surface area of a textile floor covering, defined as 1 m
3.4
total carpet weight
TCW
total mass of a textile floor covering per unit area in g/m
3.5
use-layer
part of a textile floor covering directly exposed to traffic
Note 1 to entry: The use-layer is often also called “use-surface”.
oSIST prEN 17903:2023
prEN 17903:2023 (E)
3.6
total use-layer weight
TUW
total mass of the defined use-layer per unit area in g/m
Note 1 to entry: In the case of pile carpets the TUW is identical with the total pile weight (TPW).
Note 2 to entry: For non pile carpets this is the weight of all yarns that form the use-layer, including those yarn parts
that penetrate the integral ground-weave or the backing layer (see figures 2, 3 and 4).
3.7
substrate
construction element, integral with the use-surface and composed of one or more layers, which serves as
a support for the use-surface.
Note 1 to entry: For the purpose of this standard the substrate (primary backing) is considered to be part of the
backing.
Note 2 to entry: The substrate is often also called “primary-backing”.
3.8
Backing
CB
one or more layers separately attached to the use-surface
Note 1 to entry: These layers can be of textile nature or non-textile nature. All materials in a pile floor covering other
than the pile yarn.
Note 2 to entry: The backing is often also called “carpet backing” or “secondary backing”.
3.9
total backing weight
TBW
total mass of all materials used in the backing per unit area in g/m
3.10
ground weave
GW
part of a woven carpet that forms the integral backing based on the weaving pattern
Note 1 to entry: A ground weave can be found in woven pile carpets or in flat woven carpets.
Note 2 to entry: In some cases an additional backing (CB) might be applied to carpets having a ground weave.
3.11
total pile
all portions of yarns or fibres used to form the tufts or loops above, below and within the substrate
oSIST prEN 17903:2023
prEN 17903:2023 (E)
3.12
total pile weight
TPW
mass of the pile yarn including that forming the base of the tufts or held in the substrate, but excluding
any backing compound adhering to the pile yarn
Note 1 to entry: The TPW is reported as mass of total pile per unit area above, within and below the substrate,
in g/m .
Note 2 to entry: TPW = TCW - TBW
3.13
surface pile
part of a textile floor covering consisting of textile yarns or fibres, projecting from the substrate and acting
as use-layer
Note 1 to entry: The surface pile is often also called “pile” or “effective pile”.
3.14
surface pile weight
SPW
difference in the mass of a textile floor covering before and after the pile above the substrate (effective
pile or surface pile) has been shorn away
Note 1 to entry: The SPW is reported as mass of pile per unit area above substrate in g/m .
3.15
dead pile
part of the pile yarn not being part of the use-layer
3.16
dead pile weight
DPW
mass of pile not being part of the use-layer, in g/m
Note 1 to entry: DPW = TPW-SPW
3.17
filler
relatively inert solid material added to a plastic or to an adhesive to modify its strength, permanence,
working properties or other qualities, or to lower costs
Note 1 to entry: Two classes of filler have to be considered:
— chemically inert fillers, e.g., china clay or wood flour or chalk (limestone);
— reinforcing fillers like silicates, carbon black, fibrous materials or aluminium powder that markedly
enhance the performance of a polymer.
Note 2 to entry: A filler only used to reduce cost is termed an “extender”.
3.18
polymer
molecule containing a chain of at least three monomer units which have entered into a covalent bond
with at least one other monomer unit or other reactant.
oSIST prEN 17903:2023
prEN 17903:2023 (E)
Note 1 to entry: See REACH Article 3(5)
3.18.1
monomer
substance that is converted via the polymerisation reaction into a polymer chain with repeating units
3.18.2
oligomer
substance that is converted via a polymerisation reaction into a short chain with at least 2 repeating units
but significantly less than a polymer
Note 1 to entry: Different to Polymers having the same repeating units, a small increase in the number of repeating
units will change the physical properties.
3.18.3
bio-based polymers
polymers where the monomers used for the polymerisation are partially or in whole made from
renewable biological resources
Note 1 to entry: Also man-made organic fibres based on the transformation of natural polymers, like viscose, lyocell
and acetate count as bio-based polymers.
Note 2 to entry: Bio-based polymers can be chemically identical with polymers made from crude oil. Which makes
a clear distinction at the end-of-life stage of
