- Conclusions:
- The mean particle size distribution L50 for PFBSK+ is 12.76 µm (EC 440/2008).
- Executive summary:
Particle size distribution for PFBSK+ was determined using laser diffraction according to EC 440/2008, with reference to CIPAC MT 187 and ISO13320:2009. The mean particle size distribution L50 for PFBSK+ is 12.76 µm. The study was conducted under consideration of national standard methods with detailed documentation but was not conducted under GLP; therefore the study is considered reliable with restrictions.
