【国外标准】 Standard Test Method for Determining the Apparent Viscosity of Polyethylene Wax

4.1 This test method is used to determine a physical property of a wax and may determine the utility of the wax, as well as being a significant quality control test.1.1 This test method describes the determination of the viscosity of polyethylene wax using small-volume, concentric cylinder, rotational viscometer and a temperature bath at 140 °C.1.2 The values stated in SI units are to be regarded as standard. The units in parentheses are provided for user convenience and are not standard.1.3 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.1.4 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.
