- Executive summary:
A study was conducted to determine the particle size distribution of the test substance in accordance with guidelines to meet the requirements of European Regulation (EC) No. 1107/2009, and the US EPA Office of Chemical Safety and Pollution Prevention (OCSPP), Series 830: Product Properties Test Guidelines. The particle size distribution was assessed using a technique based on laser diffraction in accordance with CIPAC MT 187. The test substance was determined to have d(0.1), d(0.5) and d(0.9) values of 53, 217 and 439 μm, respectively. d(0.1) is the diameter where 90% of the distribution is above and 10% is below. d(0.5) is the diameter where 50% of the distribution is above and 50% is below. The is referred to as the Mass Median Diameter (MMD). d(0.9) is the diameter where 10% of the distribution is above and 90% is below.
Reference
A sample labelled B was analysed but not reported since the test item had agglomerated on analysis.
