Figure 1 — Typical scheme for a testing programme concerning several characteristics with testing
steps in the field and in the laboratory
End-of-life tyres consist mainly of passenger and commercial vehicle tyres, and truck tyres manufactured for
distribution in the European market. 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 Technical Specification. Determination of additional
dimensions/impurities according to the test methods specified in normative Annexes A, B, C and D may be
performed if required by agreement between the producer and the customer or at the producer's own will.
European Standards are needed for the production, trade and use of the materials from end-of-life tyres. They
are also useful for buyers of materials, regulators, controllers and laboratories.

The materials produced at different stages of the treatment processes, primarily by size reduction, of end-of-
life tyres are as follows:
 cuts: typically 300 mm and above;
 shreds: typically 20 mm – 400 mm;
 chips: typically 10 mm – 50 mm;
 granulates: typically 0,8 mm – 20 mm;
 powders: typically under 0,8 mm;
 steel;
 textiles.
They may be distinguished mainly according to their dimension(s).

dimension(s) of the materials produced from all categories of end-of-life tyres at all steps of the treatment
process as well as for the determination of impurities.
The test methods described in this Technical Specification include sample collection and the preparation of a
representative sample based on a sampling plan for the purpose of determining dimensions and impurities.
This Technical Specification does not cover the operational performance or fitness for use of the materials
which are deemed to be a function of agreement between the producer and the customer.
NOTE This Technical Specification does not cover downstream products prepared from the materials, including
reclaimed or devulcanized rubber, surface-modified powders and pyrolytic output.
This Technical Specification does not purport to address safety concerns associated with its use. It is the
responsibility of the user of this Technical Specification to establish appropriate safety and health practices
and determine the applicability of regulatory limitations prior to use.
