Information collection and use While using our site, we may ask you to provide us with certain personally identifiable information that can be used to contact or identify you. 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.

Historical Version s – view previous asrm of standard. C with a programmable timer. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials.
Dilute Solution Viscosity of Polymers
Standards can be obtained from appropriate standards authorities. The liquid is then brought above the upper graduation mark on the viscometer. To request a quote for this test or others Click Here.

C using the same 1B size of suspended-level Ubbelohde type viscometer for both measurements. The ratio of the natural logarithm of the relative viscosity to the mass concentration of the polymer.

PET – Intrinsic Viscosity – ASTM D – RPV-2 Polymer Viscometer – Automated Viscometers
Specific hazards statements are given in Section 8. ISO also uses Type 1C Ubbelohde viscometer, rather than the 1B, and reports viscosity number, rather than inherent viscosity.

The solution and viscometer are placed in a constant temperature water bath.
