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 17307:2026) 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.
Introduction
WARNING — Persons using this document should be familiar with normal laboratory practice.
This document does not purport to address all of the safety problems, if any, associated with its
use. It is the responsibility of the user to adopt appropriate safety and health practices and to
ensure compliance with any national regulatory conditions.
1 Scope
This document specifies a method for the identification of the type of elastomers in granulates or powder
derived from End-of-Life Tyres (ELT).
The method specified is a qualitative method only.
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.

4 Principle
A representative sample of sufficient quantity of granulate or powder sample is homogenized in order to
take a small representative aliquot for solvent extraction and then subjected to pyrolysis at elevated
temperature. Few drops of the liquid pyrolysis products are then diluted in dichloromethane for the GC-
MS analysis. The use of the mass-spectrometric detector is a mean for improving the sensitivity and
reliability of the identification of the elastomers present in low or trace amount, with threshold limit
estimated to about 5 %.
The use of this document pre-supposes sufficient working knowledge of the principles and techniques of
gas chromatography/mass-spectrometry (GC-MS) for the analyst to perform the operations d
