This standard provides a manual torque test method for the measurement of torque retention of Encasement containers with continuous threaded caps. This test method is applicable to containers of various designs and materials, enabling the evaluation of torque retention performance of threaded caps under controlled conditions. Non-automated spring torque meters or torque wrenches are used during the testing process to ensure the accuracy of torque measurement. The standard also specifies that measurement results should be in SI units or inch-pound units alone, emphasizing the environmental conditions and safety specifications to be followed during testing. This method has important implications for Encasement development and engineering evaluation.
