Link to relevant study record(s)

Reference

Endpoint:

particle size distribution (granulometry)

Type of information:

experimental study

Adequacy of study:

key study

Study period:

08 - 22 Jun 1984

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Qualifier:

according to guideline

Guideline:

OECD Guideline 110 (Particle Size Distribution / Fibre Length and Diameter Distributions) - Method B: Fibre Length and Diameter Distributions

Principles of method if other than guideline:

This study could not be performed in accordance with the OECD Guideline for Testing Chemicals No. 110 "Particle Size Distribution/Fibre Length and Diameter
Distribution". It was performed by the sieving and light diffraction method.

GLP compliance:

yes

Type of method:

Laser scattering/diffraction

Remarks:

coarse section: sieving

Type of particle tested:

primary particle

Type of distribution:

mass based distribution

Mass median aerodynamic diameter:

310 µm

No.:

#1

Size:

> 400 µm

Distribution:

42 %

No.:

#2

Size:

< 4 µm

Distribution:

1.2 %

Conclusions:

The test item showed a median of mass distribution of 310 µm (width). The coarse section was analysed by sieving, the fine fraction by laser beam diffraction.

Description of key information

The test item showed a median of mass distribution of 310 µm (width). The coarse section was analysed by sieving, the fine fraction by laser beam diffraction. The percentage of particles <4 µm is 1.2%, the percentage of particles >400 µm is 42%.
