15、recycling processes and in material recovery into different applications, mainly in the field of civil engineering. This document does not provide any criteria to select whole tyres to be reused in their original application, i.e. to be mounted on a vehicle. See Figure 1 for an overview of the whole

16、 process. Figure 1 General scheme of the process to generate end of life tyres and their final processing The criteria established in this document focus on determining the conditions under which a whole end of life tyre (WELT) can be used for materials recovery. From a legal point of view, in Europ

17、e, end of life tyres are considered as waste, listed in the European Waste Catalogue with code 16.01.03, tyres removed from vehicles. The criteria for establishing when ELT cease to be waste are ultimately drafted in the EU legislation, by the relevant Directives and their further adoption into nati

18、onal regulations. The purpose of this document is to facilitate those who make the decision to establish the end of the waste status. This document also aims to overcome the limitations to the use of WELT in certain PD CEN/TS 17045:2017 CEN/TS 17045:2017 (E) 5 applications and to clarify the conditi

19、ons under which they can be used for recycling or recovery process in compliance with all conditions ensuring no negative impact to health and environment. The document aims to increase consumer confidence in the applications of used tyres and facilitate the development of the market by the introduc

20、tion of a specific set of parameters to ensure the quality and consistency of whole tyres to be used for both in recycling and recovery applications. Compliance with the criteria set in this standard, results in the protection to the human health and the environment. WARNING This document does not p

It is the responsibility of the user of this document to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

22、 6 1 Scope This European Standard provides criteria for the selection of whole end-of-life tyres (WELT) under different classes based on their size. It also provides criteria for determination of their suitability to be used in recycling and material recovery processes. The processes described in th

23、is document include sorting of WELT in order to determine their acceptance in recovery and recycling processes. Criteria regarding the reuse of tyres to be mounted again in a vehicle are not addressed in this document. This document does not cover the operational performance of the applications or t

24、he requirements of the materials for certain applications, which are usually agreed between the manufacturer and the customer. Solid tyres are excluded from the scope of this document. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document an

34、 mounted on a vehicle again 4 General information on tyres 4.1 General The information on tyres contained in this clause is not related with the recycling and recovery itself but pretend to maintain homogenous criteria on this step in comparison with the general concepts and information related with

35、 new and in use tyres. 4.2 Categories of whole tyres Different applications of the WELT may require different properties such as crush strength, shock absorption and vibration absorption to ensure the feasibility of the recovery process. These properties will depend in many cases on the category of

36、tyre which also determines its dimension. The categories of tyres are the following: Scooter, Motorcycle Passenger car Light trucks Truck and bus Industrial Agro and Forestry In addition to these categories there are also solid tyres, which rather than a hollow structure, are completely filled with

37、elastomeric material. This kind of tyres have different physical characteristics, and are not covered by this document. 4.3 General composition of tyres Each single tyre has its own specific chemical composition. Nevertheless, all tyres here considered will contain rubber, metal and textile. The per

38、centages of these materials typically depend on: size, type of tyre, intended use for the tyre and the manufacturer. The typical materials breakdown in percentages is shown in Table 1. Table 1 Average composition of different categories of tyres Material Passenger car average composition Truck and b

39、us average composition Rubber 78 % 75 % Metal 16,5 % 25 % Textile 5,5 % 1 % 4.4 Relevant information from tyre marks Generally, tyres are marked with several inscriptions providing useful information for their use when mounted on a vehicle. For WELT, most of this information is not relevant for recy

40、cling and recovery purposes. The main parameters useful for this purpose are the size and the age. PD CEN/TS 17045:2017 CEN/TS 17045:2017 (E) 9 The size usually determines both the process and the WELT possible application in the form of whole tyre. Especially for civil engineering applications a cl

41、assification by sizes is important to allow the uniformity of the structures to be built. There are three dimensional parameters generally selected for their characterization: Tyre width (WWW) Aspect ratio (AA) Inner diameter (RR) With some exceptions, those three parameters are marked in the sidewa

42、ll of the tyres in the following way: WWW / AA - RR NOTE Further explanation on tyre marks can be found in ISO 4000-1. The age of the tyre is located on the sidewall, expressed as date of manufacture. It is marked in the form of a group of four digits, the first two showing the week and the last two

43、 the year of manufacture. For tyres manufactured before 2000, rather than two, there are three digits marked on sidewall, the first two digits expressing the week and the last digit expressed the year of the decade of 1990s. 5 General criteria for selection of tyres 5.1 General The main reason to es

44、tablish acceptance criteria for whole used tyres to be recycled and/or recovered is to avoid the introduction in those processes of material which might lead to a non-conformity product. 5.2 describes some features that could affect the potential use of WELT and 5.3 establishes the requirements for

45、selection. The general requirements for the selection of whole tyres aim to avoid the introduction of harmful substances via contamination, which might impact on human health, environment, or on the quality of the products or applications obtained. The compliance with the requirements established in

46、 this document does not guarantee the suitability in the recycling or in their use in several applications, as it depends on other factors related to the application itself. 5.2 describes some features that could affect the potential use of WELT and the 5.3 establishes the requirements for selection

47、. 5.2 Criteria for the selection and use of whole tyres 5.2.1 Source Tyres might come from stockpile or other location where they have been mixed with any other type of waste. In such a case, care should be taken in order to ensure that WELT are not contaminated by other waste. 5.2.2 Exposition to f

48、ire WELT might come from stockpiles that have been exposed to fire. In those stockpiles, even those tyres not yet being burned, have been into contact with the compounds of decomposition of the tyre caused by fire. PD CEN/TS 17045:2017 CEN/TS 17045:2017 (E) 10 Tyres that have been partially burnt or

49、 that may be contaminated by burning tyres shall not be used for recycling processes. 5.2.3 Presence of greases and oils Depending on the source, some tyres might have been in contact with greases and oils that may contaminate the materials obtained in the recycling process or affect its use in most applications. It is especially important to avoid such tyres in a recycling process. 5.2.4 Fillings Some tyres are filled with polymeric material in order to prevent punctures during their use in vehicles. The composition of these tyres is different
