안녕하십니까?
금번 ASME Sec.VIII Div.2, 2007 edition에서 많은 부분이 변경되어 문의하고자 합니다.
Para.3.4에서 Two set of tension specimens and one set of Charpy impact specimens를 요구하고 있습니다. 하기에 언급된 Condition A와 B가 정확하게 어떻게 하라고 하는지 모르겠습니다.
적용해 보신분이 있으시면 advise하여 주시면 감사하겠습니다.
One set each of the tension specimens shall be exposed to heat treatment condition A
The second set of tension specimens and the set of Charpy specimens shall be exposed to heat treatment Condition B
a) Condition A-Temperature shall be no lower than the actual maximum vessel-portion temperature, less 14°C. Time at temperature shall be no less than 80% of the actual holding time of the vessel portion exposed to the maximum vessel-portion temperature.
b) Condition B-Temperature shall be no higher than the actual maximum vessel-portion temperature, plus 14°C. Time at temperature shall be no more than 120% of the actual holding time of the vessel portion exposed to the minimum vessel-portion temperature.
