3.1 This measurement of flow gives results that cannot be predicted with viscosity measurements, due to surface tension and density effects. The measured flow is related to flow performance of viscous materials sprayed on aircraft surfaces or other large structures.

1.1 This test method describes a procedure for the determination of the flow of a standard volume of a semisolid or thick liquid under its own weight.

1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

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.
