(Main)Materials obtained from end of life tyres (ELTs) - Sampling method for granulates and powders stored in big-bags
Materials obtained from end of life tyres (ELTs) - Sampling method for granulates and powders stored in big-bags
This Technical Specification specifies a method for obtaining a laboratory 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.
Materialien aus Altreifen - Probenahme von Granulaten aus dem Schleifprozess von Altreifen - Methode, die auf der Entnahme einer relevanten Probe aus einem Big-Bag aus übereinanderliegenden Schichten basiert
Diese Technische Spezifikation legt ein Verfahren fest, bei dem aus Altreifen, die in Großsäcken (big-bags) gelagert werden, eine Laborationsprobe aus Gummigranulaten oder -pulver erhalten wird.
Verschiedene Einzelproben, welche die durchschnittliche Teilchengrößenverteilung innerhalb des Großsacks darstellen, werden aus unterschiedlichen Höhen innerhalb des Großsacks gezogen. Aus diesen Einzelproben wird eine repräsentative Probe erstellt.
Matériaux obtenus à partir de pneus usagés non réutilisables (PUNR) - Méthode d'échantillonnage de granulats et de poudrettes stockés dans des big-bags
La présente Spécification technique prescrit une méthode permettant d'obtenir un échantillon pour laboratoire de granulats ou de poudrettes de caoutchouc issus de pneus usagés non réutilisables, qui ont été stockés dans des « big-bags ».
Plusieurs prises élémentaires sont prélevées à différents niveaux dans le « big-bag » ; elles représentent la distribution granulométrique moyenne dans le « big-bag ». Un échantillon représentatif est obtenu à partir de ces prises élémentaires.
Snovi iz izrabljenih avtomobilskih gum (ELT) - Metoda vzorčenja granulatov in praškov, shranjenih v velikih vrečah
Ta tehnična specifikacija določa metodo za pridobivanje laboratorijskih vzorcev granulatov in praškov, pridobljenih iz izrabljenih avtomobilskih gum, ki so shranjeni v velikih vrečah.
Pridobi se več enot vzorcev na različnih ravneh znotraj velike vreče, ki predstavljajo povprečno porazdelitev velikosti delcev v veliki vreči. Iz teh enot vzorcev izhaja reprezentativni vzorec.

This Technical Specification (CEN/TS) was approved by CEN on 2 March 2018 for provisional application.
The period of validity of this CEN/TS is limited initially to three years. After two years the members of CEN will be requested to
submit their comments, particularly on the question whether the CEN/TS can be converted into a European Standard.
CEN members are required to announce the existence of this CEN/TS in the same way as for an EN and to make the CEN/TS
available promptly at national level in an appropriate form. It is permissible to keep conflicting national standards in force (in
parallel to the CEN/TS) until the final decision about the possible conversion of the CEN/TS into an EN is reached.

Introduction
Particle size distribution and related parameters are key measurements for product characterization of
size-reduced materials, such as granulates and powders derived from End-of-life Tyres (ELTs). To
obtain an accurate particle size distribution, a representative sample of the material to be tested will be
taken according to the principle that every particle of the sample that represents the lot will have an
equal probability of being included in the sample.
Sampling criteria to assess characteristics of granulates and powders at different stages of a production
process by size reduction of End-of-life tyres are given in prEN 14243-2:2017, Clause 5.
When the lot to be characterized is a big-bag, particular attention has to be given in order to obtain a
representative sample(s) because of the tendency of the stored material to segregate over time with the
smaller particles settling in the lower part of the big-bag.
