Description of key information

The proportion of test material having a respirable particle size less than 5.4 µm was 1.23 %.

Additional information

The particle size of the test material was investigated in accordance with the standardised guideline OECD 110 under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria for assessing data quality set forth by Klimisch et al. (1997).

The volumetric distribution was determined using a sieve and cascade impactor. The proportion of test material having an inhalable particle size less than 100 µm was 12.3 %; the proportion having a thoracic particle size less than 10.2 µm was 3.47 %; and the proportion having a respirable particle size less than 5.4 µm was 1.23 %.
