Threaded joints and tubing joints no longer needed to be leak tested in accordance with the ASME B31.3 leak test. The design minimum temperature is required to determine the impact test requirements of ASME B31.3. As the temperature is decreased, the notch toughness of the material drops. Thus, impact tests are required under conditions of sufficiently low temperature and high stress to ensure that the material has adequate toughness to avoid a brittle fracture. . Current B31.3 Toughness Testing Requirements • Table 323.2.2 Austenitic Stainless Steels: B- 4 Base metal and weld metal deposits shall be impact tested in accordance with para. 323.3. • When impact testing is required by Table 323.2.2, paragraph 323.3.4 and sub-paragraphs require Charpy impact testing at a temperature not higher than theASME B31.3 INTERPRETATIONS NO. 15 Replies to Technical Inquiries April 1, 1996, Through March 31, 1997 .
