Applicant's summary and conclusion
- Conclusions:
- The test item Chlorobutanol Hemihydrate has the following particle size distribution according to the definition of ISO 13320:2009 and HSA-method (S) 13X11001.02. The volume percentages of D(10)-, D(50)- and D(90)- values are listed (see appendix 1 and table 1). A D90 value of 100 μm means that 90 vol % of the particles are smaller than 100 μm.
- Executive summary:
The particle size distribution of the test item was determined with static laser light scattering according to ISO 13320:2009 and HSA-method (S) 13X11001.02.
