ASTM D Standard Test Method for Determining Inherent Viscosity of Poly( Ethylene Terephthalate) (PET) by Glass Capillary Viscometer. This standard is issued under the fixed designation D ; the number specified in this ASTM test method is one of the options in the ISO method. ISO also.

Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. If we make any material changes to this aastm policy, we will notify you either through the email address you have provided us, or asfm placing a prominent notice on our website.
Equipment xstm at Plastics Technology Laboratories, Inc: If the material is filled, it is important to specify percent filler. C with a programmable timer.
PET – Intrinsic Viscosity – ASTM D4603
The test method requires a 0. The method requires that three successive flow times are obtained within 0. Show 5 10 15 20 25 per page. Solvent and solution flow times are measured at 30 deg. Caution should be taken when handling mercury and mercury containing products.
Commonly a sample size of mg. The RPV-2 software automatically calculates the Intrinsic Viscosity from each single determination using the Billmeyer equation.

PET – Intrinsic Viscosity – ASTM D – RPV-2 Polymer Viscometer – Automated Viscometers
It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. The ratio of the relative viscosity dd4603 to the mass concentration of the polymer.
Information collection and use While using our site, we may ask you to provide us with d46003 personally identifiable information that can be used to contact or identify you. It is used d46603 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.
It must be controlled so that the processability and end properties of the resin remain in a desired range. The solution and viscometer are placed in a d46003 temperature water bath.

Specific hazards statements are given in Section 8. 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.
Dilute Solution Viscosity is used as an indication of the molecular weight of polymers.
