PET Standards ASTM D4603

PET Standards ASTM D4603

Part Code:

20502/3 Pack of 3 PET, ASTM D4603 standards (reference samples produced by the PSL Polymer testing laboratory)

20503/10  Pack of 10 PET, ASTM D4603 standards (reference samples produced by the PSL Polymer testing laboratory)

 

Reference polymer values are measured in accordance with ASTM D4603 (Standard Test Method for Determining Inherent Viscosity of Poly(Ethylene Terephthalate) (PET) by Glass Capillary Viscometer) using the PSL Rheotek RPV-2 (2) AutoPET Polymer Viscometer and F100 digital reference thermometer. Intrinsic viscosity results were automatically calculated by the built-in software using the Billmeyer equation.

 

Example RESULT

Intrinsic Viscosity

Mean Value Measured

0.798 dL/g

Standard Deviation of the mean

0.61% with 9 degrees of freedom

 

The mean value was obtained from at least 5 different preparations. Each determination was made by measuring a preparation of the sample in accordance with the method stated above.

Poulten Selfe and Lee Ltd has many years of experience in dilute solution viscosity. This reference sample gives the customer a direct comparison with results generated on preparations of the same sample by the PSL Polymer Testing Laboratory. Please feel free to share your data with Poulten Selfe and Lee Ltd. We will be pleased to discuss your solution viscosity results.
