- Principles of method if other than guideline:
- The granulometry of the sample was determined by sieving. Sieving is a method where material is separated to finer and rougher sections determined by sieve size. Material is fed on the sieve and then the motion energy between the sieve and the material causes finer material to go through the sieve. The motion can be done efficiently by using ultrasonic washing device. The sieve with material is drowned to washing device and then lifts slowly up. The sieve is kept in the motion so that material is rotating on the sieve. Lifting up and ultrasonic produce an absorbing effect that makes finer material go through the sieve more efficiently. After sieving finer material goes on the top of the next and finer sieve and is sieved again. This continues until the finest material is separated. Residuals separated by sieving are filtered with suction, then dried and weighed. Weighed residuals are reported and the particle size distribution is calculated. The sieves used in sieving were classified ASTM’s sieves and the grain sizes are from 0,020mm to 3,36mm. The ultrasonic washing was done with Finnsonic M40i.

Description of key information
The granulometry of the sample was determined by sieving. Sieving is a method where material is separated to finer and rougher sections determined by sieve size. Material is fed on the sieve and then the motion energy between the sieve and the material causes finer material to go through the sieve. The motion can be done efficiently by using ultrasonic washing device. The sieve with material is drowned to washing device and then lifts slowly up. The sieve is kept in the motion so that material is rotating on the sieve. Lifting up and ultrasonic produce an absorbing effect that makes finer material go through the sieve more efficiently.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
