This document specifies methods for obtaining a sample of rubber granulates or powders derived from end-of-life tyres which have been stored in big-bags and small-bags.
Sample increments at different levels within the bag are obtained, which represent the average particle size distribution within the bag. From these sample increments, a representative sample is derived.
The methods specified in this document are applicable, for example, when the samples are to be tested for e.g. bulk density, durability, particle size distribution, moisture content, ash content, ash melting behaviour, calorific value, chemical composition, impurities.
