Reference
Endpoint:
particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
28 September 2010 to 25 November 2010
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP complaint, guideline study, available as unpublished report acceptable without restrictions
Reference:
Composition 1
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
Test material information:
Composition 1
No.:
#1
Size:
< 100 µm
Distribution:
87.7 %

The results of the sieving procedure are shown below:

 Measurement

Result 

Mass of test item transferred to sieve 

10.10 g

 Mass of test item passed through sieve

8.86 g

Proportion of test item <100µm 

87.7%
Conclusions:
In an OECD 110 Granulometry (Screening Test) the proportion of palladium (II) acetate <100 μm was 87.7%
Executive summary:

This is a GLP compliant, guideline study considered suitable for use as the key study for this endpoint. The proportion of palladium (II) acetate < 100 μm is 87.7%

Description of key information

The proportion of palladium (II) acetate < 100 μm is 87.7%.

Additional information

O’Connor and Woolley (2011) is a GLP compliant study following OECD TG 110 and is considered suitable for use as the key study for this endpoint. The proportion of palladium (II) acetate < 100 μm is 87.7%
