This amendment incorporates by reference Section IX of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) into Part 195 for qualification of welders. Welder qualification is presently limited to Section 3 of API Standard 1104 under Part 195. Allowing the use of the ASME Code for welder qualification when necessary and appropriate to do so will bring the requirements for hazardous liquid pipelines into line with 49 CFR Part 192, the Federal safety standards for gas pipelines.
