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

The limiting value of the reduced viscosity or the inherent viscosity at infinite dilution of the polymer. The test method requires a 0.

Highly crystalline forms of PET that are not soluble in this solvent mixture will require a different procedure.

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.

It is used for polymers that dissolve completely without chemical reaction or d6403 and can provide an excellent determination of lot-to-lot consistency or be used to compare molded parts to original resin for determinations of degradation from molding.
