The ASTM D7836-13 (2020) standard specifies a test method for the measurement of yield stress of Coatings, inks and related liquid materials. Yield stress refers to the minimum stress value at which a liquid material begins to flow, reflecting its rheological characteristics and application performance. This standard provides yield stress measurement techniques for all types of Coatings and inks, including the use of appropriate instruments and methods to determine the behavior of the material under static and dynamic conditions. The implementation of this standard can help manufacturers better understand and adjust the flowability, coatability and other performance of the material during product design, quality control and application. This standard helps to improve the production and application conformity of coatings and inks, ensuring that they perform as expected in various application environments.
