Materials and methods

Test guideline
Qualifier:
no guideline followed
Guideline:
other:
Principles of method if other than guideline:
Lowest mesh size and median mass diameter, as the OECD guideline for testing of chemicals, No. 110, Particle size distribution/Fiber length and diameter could not be used, since the particle distribution of the substance is too large.
