ASTM D2290-19a

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.
Designation: D2290 − 19a
Standard Test Method for
Apparent Hoop Tensile Strength of Plastic or Reinforced
