Materials and methods
Test guideline
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
- Principles of method if other than guideline:
- The granulometry, i.e. particle size, of the samples are 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 washing 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 it's 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 are classified ASTM’s sieves and the grain sizes are from 0,020mm to 3,36mm /7/. The ultrasonic washing is done with Finnsonic M40i.

- 273-836-9
- EC Name:
- Speiss, copper
- Cas Number:
- 69029-97-6
