Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

particle size distribution (granulometry)
Type of information:
experimental study
Adequacy of study:
key study
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: GLP complaint, guideline study, available as unpublished report acceptable without restrictions
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. QA statement)
Type of method:
< 100 µm
92.7 %

The results of the sieving procedure are shown below:



Mass of test item transferred to sieve 


 Mass of test item passed through sieve


Proportion of test item <100µm 

In an OECD 110 Granulometry (Screening Test) the proportion of Tetrakis (triphenylphosphine) palladium (solid only) <100 μm was 92.7 %
Executive summary:

This is a GLP compliant, guideline study considered suitable for use as the key study for this endpoint. The proportion of Tetrakis (triphenylphosphine) palladium (solid only) < 100 μm was 92.7 %

Description of key information

The proportion of tetrakis (triphenylphosphine) palladium <100 μm was 92.7 %.

Additional information

Walker and White (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 tetrakis (triphenylphosphine) palladium < 100 μm was 92.7 %.
