40、for the testing laboratory(ies)1234567“in the laboratory“ “in the laboratory“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

41、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 Technic

42、al 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 producers own will. European Standards are needed for the productio

43、n, trade and use of the materials from end-of-life tyres. They are also useful for buyers of materials, regulators, controllers and laboratories. DD CEN/TS 14243:2010CEN/TS 14243:2010 (E) 7 The materials produced at different stages of the treatment processes, primarily by size reduction, of end-of-

44、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). DD CEN/TS 14243:2010CEN/T

45、S 14243:2010 (E) 8 1 Scope This Technical Specification provides definitions for the categories of materials produced from end-of-life tyres based on their dimension(s) or impurities. It also provides test methods for the determination of the dimension(s) of the materials produced from all categorie

46、s 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 dim

47、ensions 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

48、 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. 2
