This draft European Standard is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee
CEN/TC 366.
If this draft becomes a European Standard, CEN members are bound to comply with the CEN/CENELEC Internal Regulations
which stipulate the conditions for giving this European Standard the status of a national standard without any alteration.

This draft European Standard was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

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
United Kingdom.
Recipients of this draft are invited to submit, with their comments, notification of any relevant patent rights of which they are
aware and to provide supporting documentation.

European foreword
This document (prEN 14243-1:2026) has been prepared by Technical Committee CEN/TC 366 “Materials
obtained from End-of-Life Tyres (ELT)”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 14243-1:2019.
prEN 142431-1:2026 includes the following significant technical changes with respect to
EN 14243-1:2019:
— Clause 3 has been updated.
EN 14243, Materials obtained from End-of-Life Tyres (ELT), consists of the following parts:
— Part 1: General definitions related to the methods for determining their dimension(s) and impurities
— Part 2: Granulates and powders – Methods for determining the particole size distribution and
impurities, including free steel and free textile content
— Part 3: Shreds cuts and chips – Methods for determining their dimension(s) including protruding
filaments dimensions
Introduction
This document is used in conjunction with the other parts of EN 14243 series. Figure 1 shows how these
series of standards cover the testing programs, conducted both in the field and in the laboratory, needed
to characterize each product category.

testing steps in the field and in the laboratory
End-of-life tyres consist mainly of passenger and commercial vehicle tyres, truck, earthmover and
agricultural tyres manufactured for distribution in the European market that are no longer suitable for
their original purpose. Products from end-of-life tyres are used as a secondary raw material finding a
wide range of applications. The principal categories of materials from end-of-life tyres are defined on the
basis of their dimension(s) according to this document.
prEN 142431-1:2026 (E)
1 Scope
This document provides general definitions for sample collection and preparation of a representative
sample based on a sampling plan for the purpose of determining dimensions and impurities.
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.

for determining the particle size distribution and impurities, including free steel and free textile content

for determining their dimension(s) including protruding filaments dimensions
3 Terms and definitions
For the purposes of this document, the terms and definitions given in [www.goldbook.iupac.org]
referenced as IUPAC definition, and the following apply.

3.1 Sampling and sample preparation
3.1.1
sample
portion of material selected from a larger quantity of material
[SOURCE: IUPAC definition]
3.1.2
sub-sample
portion of a sample
3.1.3
increment
sub-portion of material extracted in a single operation by the sampling device
[SOURCE: ISO 13909-1:2016, 3.15, modified]
3.1.4
characteristic
property which helps to identify or differentiate items of a given population
Note 1 to entry: The characteristic may be either quantitative (by variables) or qualitative (by attributes).
3.1.5
lot
defined quantity of material for which a characteristic is to be determined
Note 1 to entry: In sampling standards the lot is also designated as the “scale”.
Note 2 to entry: The lot (or the scale) is a stated weight or volume of material that is considered appropriate for
assessing a given characteristic of the material. When several characteristics are determined, the corresponding
lots may not be identical.
Note 3 to entry: Variations occurring in the material on a smaller scale than the defined lot are not taken into
account and are deemed not to be of relevance.
