Revision of E2448-18 Standard Test Method for Determining the Superplastic Properties of Metallic Sheet Materials


None Provided


The reapproval of the standard in 2018 added definitions of the terms indicated temperature and nominal temperature that were being developed in E28.04. This action was premature, because the definitions changed in response to negatives at the main committee ballot level. This work item corrects the definition of indicated temperature to agree with the definition in E6, the terminology standard, removes the definition of nominal temperature, which is not in E6, and adds the definition of specified temperature, which replaced nominal temperature.
