Particle size distribution (Granulometry)
Administrative data
- Endpoint:
- particle size distribution (granulometry)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- December 18, 2013 - July 17, 2014
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: The study is not a guideline study but is well documented and meets generally accepted scientific principles. Relevance: the particle size distribution is not a REACH requirement as the substance is only marketed and used in a non-solid form.

Materials and methods
Test guideline
- Qualifier:
- no guideline available
- Principles of method if other than guideline:
- According to REACH Regulation (EC) No 1907/2006 Article 13(3) tests on substances shall be conducted in accordance with the test methods laid down in a Commission Regulation or in accordance with other international test methods recognised by the Commission or the Agency as being appropriate. No particle size distribution test method is laid down in the relevant Regulation (EC) No 440/2008. The international OECD 110 test guideline ‘Particle Size Distribution/FibreLength and Diameter Distributions’ dates from 1981 and describes two methods in detail; both methods have restrictions and are not applicable to the entire size range. ECHA’s document ‘Guidance on information requirements and Chemical SafetyAssessment-Chapter R.7a: Endpoint specific guidance’ stipulates that many methods are available for particle size measurements but none of them is applicable to the entire size range.
For the particle size determination of this substance, manual sieve analysis was performed using different sieve sizes. Optical and SEM images are provided to confirm particle size. - GLP compliance:
- no
- Type of method:
- sieving
- Type of distribution:
- mass based distribution

Applicant's summary and conclusion
- Conclusions:
- Using manual sieve analysis, it was determined that approx. 89% of the test substance is >150 µm, ca 10% is between 44 and 150 µm and 0% is < 44 µm.
The particle size distribution is not a REACH requirement as the substance is only marketed and used in a non-solid form. The particle size distribution test was performed on test substance that was specially prepared for REACH purposes.
