Scope

1.1 This test method covers the use of a screw-extrusiontype capillary rheometer for the measurement of flow properties of thermoplastics and thermoplastic compounds. The measured flow properties, which are obtained through laboratory investigation, may help to describe the material behavior that occurs in factory processing. 1.2 Since a screw-type capillary rheometer imparts shear energy to the material during testing, the measurements will usually differ from those obtained with a piston-type capillary rheometer (see Test Method D3835). 1.3 Capillary rheometer measurements for thermoplastics and thermoplastic compounds are described in Test Method D3835. 1.4 The values stated in SI units are to be regarded as standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. NOTE 1—There is no known ISO equivalent to this standard. The scope of this standard is mentioned in ISO 11443:2014, Plastics—Determination of the fluidity of plastics using capillary and slit-die rheometers,” Annex C, “Uncertainties in the determination of shear viscosity by capillary extrusion.” 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
