The MDMT module determines the Minimum Design Metal Temperature and whether impact testing is required according to ASME BPVC VIII-1 UCS-66, UCS-66.1, UCS-68 and UHA-51. It evaluates the governing thickness, the basic exemption temperature from Fig. UCS-66 (curves A/B/C/D), the temperature reduction from the coincident stress ratio (Fig. UCS-66.1), the PWHT credit (UCS-68) and the austenitic exemptions of UHA-51, as well as the bolting exemption temperatures of UCS-66 General Note (c).
