My Account Log In. ISO also uses Type 1C Ubbelohde viscometer, rather than the 1B, and reports viscosity number, rather than inherent viscosity. You have no items to compare.
PET – Intrinsic Viscosity – ASTM D4603
Dissolution is carried out using a reaction block with stirring and heating at deg. Solvent and solution flow times are measured at 30 deg.
ASTM D4603 – 18
The solution and viscometer are placed in a constant temperature water bath. You can instruct your browser to refuse all cookies or to indicate when a cookie is being sent. Asgm using the same 1B size of suspended-level Ubbelohde type viscometer for both measurements.
