Applicant's summary and conclusion

Conclusions:
The viscosity of CAS# 756-12-7 is 0.41 mm²/s at 0.0 °C
Executive summary:

The viscosity of CAS# 756-12-7 is 0.41 mm²/s at 0.0 °C. Measurements were made using calibrated Schott-Ubbelohde Viscometers: 545-00 and 545-03. It is unknown which viscometer(s) were used for this compound's viscosity measurements. The viscometer was corrected using the Hagenbach correction. The study addresses kinematic viscosity directly, and is therefore relevant to the viscosity endpoint. It is unknown if viscometers were calibrated. Although the viscometers used in this study are compliant with ASTM D2515 and ASTM D446 standards, it is unknown if this study followed an ISO, ASTM, or OECD guideline. The study was not conducted in accord with GLP guidelines. Therefore the study is classified reliable with restrictions.
