Section VIII. This is the only article found that links ASME UG-84.2 to Charpy impact properties. A review of other code requirements with provisions for subsize Charpy specimens may be useful for comparison to A370/Table 9. The adequacy of code requirements for sub-sized Charpy testing was reviewed by Towers in 1986 (Towers, 1986).Table UG-84.2: ASME B31.3 (Process Piping) . The impact test specimen width is only 5mm (71% of the material thickness) and Table 6 specifies a temperature reduction of 11°C. The actual reduction in test temperature below the standard test temperature for this situation is the difference between these two temperatures, namely:
UG-84(c)(2) The impact test specimens shall be of the Charpy V-notch type and shall conform in all respects to Fig. UG-84. The standard (10 mm x 10 mm) specimens, when obtainable, shall be used for nominal thicknesses of 7⁄16 in. (11 mm) or greater, except as otherwise permitted in (c)(2)(a) below.
