Reference
Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP complaint, guideline study, available as unpublished report acceptable without restrictions
Qualifier:
according to
Guideline:
OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions)
Version / remarks:
Screening Test
Principles of method if other than guideline:
The method used is based on a procedure designed to comply with that given in 'Particle size distribution, fibre length and diameter distribution', June 1996 European Commission technical guidance document, which satisfies the requirements of OECD Guideline 110
GLP compliance:
yes (incl. certificate)
Type of method:
sieving
No.:
#1
Size:
100 µm
Distribution:
65.2 %

The results of the sieving procedure are shown below:

 Measurement

Result 

Mass of test item transferred to sieve 

9.98g

 Mass of test item passed through sieve

6.51g

Proportion of test item <100µm 

65.2%
Conclusions:
The proportion of test item <100 μm was 65.2 %.
Executive summary:

This is a GLP compliant, guideline study considered suitable for use as the key study for this endpoint. The proportion of carbonyl(pentane-2,4-dionato-O,O')(triphenylphosphine)rhodium < 100 μm was 65.2 %.

Description of key information

The proportion of test item less than 100 μm was 65.2%. 

Additional information

O'Connor and Woolley (2011) is a GLP compliant study, guideline study and is considered reliable and suitable for use as the key study for this endpoint.

In the OECD 110 Granulometry (Screening Test) the proportion of carbonyl(pentane-2,4-dionato-O,O')(triphenylphosphine)rhodium less than 100 μm was 65.2%.
