study was performed to investigate the particle size distribution
(granulometry) on 3 batchs of the test substance DPTU
(1,3-diphenyl-2-thiourea). The study was conducted according to ISO
13320- 1 “International standard for Laser Diffraction Measurements –
Principles of Laser diffraction” and in accordance with OECD Test
Guideline 110. The mean particle size, number in volume, of DPTU test
item, is determined to be 15.87 µm (D(4.3)), with 38.8 % of particles
presenting a diameter less than 10µm.
