Applicant's summary and conclusion

Conclusions:

The viscosity of PBSF is 1.48 mPa s at 20.0 °C

Executive summary:

The viscosity of PBSF was measured using a Brookfield LVTDT-II+ Viscometer with the ultra low (UL) adapter at various specified temperatures. The temperature was controlled through a refrigerated temperature bath/circulator connected to the sample cup jacket. Although automated viscometry is permitted by OECD TG 114, it is unknown whether this study follows an OECD, ISO or ASTM guideline. Therefore this study is classified as reliable with restrictions.
