| BSI | 2019 | 30 |
This standard provides test methods for the determination of the particle size distribution of granulates and powders, produced from all categories of end-of-life tyres at all steps of the treatment processes as well as for the determination of impurities (including free steel and free textile content). The methods described in this standard include sample collection and the preparation of a representative sample based on a sampling plan for the purpose of determining particle size distribution and impurities.
