This document provides two different methods for the quantitative estimation of non-metallic content remaining adhered to the steel wire obtained from the recovery of materials from end-of-life tyres.
The pyrolysis method is considered as the reference method while the hydrostatic method is considered as an in-situ method.
This European Standard includes sample collection and the preparation of representative samples based on a sampling plan for the purpose of their characterization.
This European Standard does not cover the operational performance or fitness for use of the materials which are deemed to be a function of agreements between the manufacturer and the customer.
This European Standard does not purport to address all the safety concerns, if any, associated with its use. This European Standard does not establish appropriate safety and health practices and does not determine the applicability of regulatory limitations prior to its use.

This document specifies a method for obtaining a sample of rubber granulates or powders derived from End-of-life tyres which have been stored in big-bags.
Several sample increments at different levels within the big-bag are obtained, which represent the average particle size distribution within the big-bag. From these sample increments, a representative sample is derived.

This document specifies a method for the determination of low specific surface area of powders ELTs rubber by measuring the amount of physically adsorbed krypton gas and applying the theoretical multipoint Brunauer, Emmett and Teller (BET) method.
This document defines a specific method for powders taking into account that, in order to obtain an accurate value of specific surface area, a representative sample of the material to be tested is taken according to the principle that every particle of the sample that represents the lot have an equal probability of being included in the sample.

This document provides criteria for the sorting of whole end-of-life tyres (WELT) into different classes based on categories. It also provides criteria for the determination of their suitability to be used in recycling and material recovery processes.
The processes described in this document include sorting WELTs 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 the 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.

The purpose of this document is to provide information about a procedure based on the determination of a visual index correlated with the content of textile fibres, which are free and bounded to the rubber, of granulates. This approach is currently used by Spanish grinders in order to control the efficiency of their processes and is effective for granulates with particle sizes the bottom limit of which is more than 0,5 mm, and upper limit less than 10 mm.
NOTE   Part of this document is also the presentation of a study carried by Valoriza Servicios Medioambientales and Geneus Canarias S.L.
A test procedure for the determination of a visual index of the content of the textile fibre of a granulate sample, which is free and bounded to the rubber, from the ELT’s processing is described in UNE 53936:2015 EX: Materials produced from end of life tyres. Rubber granulates.
