ASTM D4603 – 18
You have no items to compare. In addition we may use third party services such as Google Analytics that collect, monitor and analyse this data.
The liquid is then brought above the upper graduation mark on the viscometer. Solvent and solution flow times are measured at 30 deg. C using the same 1B size of suspended-level Ubbelohde type viscometer for both measurements. Highly crystalline forms of PET that are not soluble in this solvent mixture will require a different procedure.

ISO also uses Type 1C Ubbelohde viscometer, rather than the 1B, and reports viscosity number, rather than inherent viscosity. Specific hazards statements are given in Section 8. It is used for polymers that dissolve completely without chemical reaction or degradation 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.

Thermal equilibrium is obtained within the solution. Using these integrated options ensures full integrity of data from end to end in the measurement process.
Commonly a sample size of mg. Standards can be obtained from appropriate standards authorities. Due to copyright restrictions, we are not able to provide copies of standards. My Account Log In. The method requires that three successive flow times are obtained within 0.
