Reference
Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
September 2011
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
study well documented, meets generally accepted scientific principles, acceptable for assessment
Reference:
Composition 0
Qualifier:
no guideline followed
Principles of method if other than guideline:
- Principle of test: The particle size distribution of the material was measured using sieve shaker and standard 200 mm diameter sieves. A sample of the material was weighed onto the sieves and shaken intermittently (8 seconds on / 4 seconds off) for 30 minutes.
- Parameters analysed / observed: The resultant fractions were weighed to determine the particle size distribution.
GLP compliance:
no
Type of method:
sieving
Type of distribution:
mass based distribution

Conclusions:
The median particle size of the sample of glutaric acid was 500 to 1000μm.
Executive summary:

The particle size distribution of the material was measured using sieve shaker and standard 200 mm diameter sieves. A sample of the material was weighed onto the sieves and shaken intermittently (8 seconds on / 4 seconds off) for 30 minutes. The resultant fractions were weighed to determine the particle size distribution. The median particle size of the sample of glutaric acid was found to be 500 to 1000μm.
