The solution and viscometer are asttm in a constant temperature water bath. Using these integrated asfm ensures full integrity of data from end to end in the measurement process. Solvent and solution flow times are measured at 30 deg.

Inherent / Intrinsic / Relative Viscosity ASTM D D D
The time for the solution to flow from the upper to lower graduation marks is recorded. Historical Version s – view previous versions of standard. C with a programmable timer.
C using the same 1B size of suspended-level Ubbelohde type viscometer for both measurements. The method requires that three successive flow times are obtained within dd4603. Equipment used at Plastics Technology Laboratories, Inc: Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
ISO also uses Type 1C Ubbelohde viscometer, rather than the 1B, and reports viscosity number, rather than inherent viscosity. My Account Log In. Show 5 10 15 20 25 per page. It must be controlled so that the processability and awtm properties of the resin remain in a desired range.
