Additional information
Particle size distribution:
The particle size distribution of C.I. Pigment Yellow 34 and C.I. Pigment Red 104 was measured using a Coulter® LS Particle Size Analyser. Four different samples from each pigment were measured. The mean particle size ranged from 17.3-24.6 µm for C.I. Pigment Yellow 34 and from 16.1-22.3 µm for C.I. Pigment Red 104, under the conditions of this test.

Dustiness testing:
The dustiness of DCC Yellow 1007 (Regular Pigment Yellow 34) was investigated according to EN 15051 using the rotating drum method. The dustiness results of sample DCC Yellow 1007 (Regular Pigment Yellow 34) are as follows (at 21ºC and RH of 44 +/-3%):
The average inhalable dustiness mass fraction is 780 mg kg-1 and is classified as low.
The average thoracic dustiness mass fraction is 118 mg kg-1 and is classified as low.
The average respirable dustiness mass fraction is 7 mg kg-1 and is classified as very low.
For C.I. Pigment Yellow 34, the respirable fraction of the inhalable dustiness mass fraction is 7/780 *100% = 0.9%
