Причина отменыThis test method covered the application with a given torque of a threaded or lug-style closure to a container, and measures the torque required to unscrew the closure from a container.

Formerly under the jurisdiction of Committee D10 on Packaging, this practice was withdrawn in January 2016 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
