Results and discussion

Viscosity
Temp.:
20°C
Parameter:
dynamic viscosity (in mPa s)
Value:
182

Applicant's summary and conclusion

Conclusions:
Whatever the viscosity value, no aspiration hasard classification is required according to EU criteria, because the test item is not made of hydrocarbons.
Executive summary:

The dynamic viscosity was 182 mPa.s, for a liquid form of Yeast extract.
