ASME B31. 3 2014 comes to be more stringent, less than 5mm, PWHT is required. More than 25 mm, PWTH can be exempted if preheat is conducted.
What is ASTM vs ISO?
ASTM is a national organization that is a part of ISO organizations. ISO is an international organization that has representations from all countries including ASTM. ISO establishes documents and updates the standards of testing materials with global consensus from the experts of the associated national organizations.
Does OSHA use ANSI?
Answer:Â A number of ANSI and other industry consensus standards have been adopted as OSHA requirements.
