Endpoint:
particle size distribution (granulometry)
Data waiving:
study scientifically not necessary / other information available
Justification for data waiving:
the study does not need to be conducted because the substance is marketed or used in a non solid or granular form

Description of key information

According to specification the physical state of the test item is solid, but furthermore described as a molten mass. Therefore, a test on granulometry cannot be performed.

Additional information

According to column 2 of REACH Annex VII, a study on particle size distribution (as required in point 7.14) does not need to be conducted if the substance is not placed on the market or used in a solid or granular form. The test substance is not placed on the market in granular form. Hence, no study on particle size distribution is required.
