As there was no effect due to shear rate, the average viscosity value can be set at 0.83 mPa.s at 30 rpm (20°C).

Conclusions:
The viscosity of di-tert-butyl peroxide is 0.83 mPas at 30 rpm (20°C).
Executive summary:

The viscosity of di-tert-butyl peroxide(CAS 110-05-4)was determined accordingto OECD Guideline 114 , and in accordance with European Chemicals Agency (ECHA), Guidance on information requirements and chemical safety assessment, Chapter R.7a, Endpoint specific guidance, May 2008.
