This standard specifies the calibrating and use of torque meters for use in Encasement applications for the measurement of applied and removed torque for continuous or intermittent thread and lug closures. The specification provides practical guidance to ensure the accuracy of torque meters and to help determine the amount of torque when sealing caps are applied or removed. The standard highlights the calibrating procedures to be followed during testing and reminds users of the need to establish appropriate safety, health and environment specifications when operating. This standard contributes to the Reliability and conformity of Encasement sealing tests.
