As referenced in section SPS 341.05, any such variance must comply with chapter SPS 303, which requires establishing an equivalency that meets the intent of the rule.
Note: The Department will recognize the applicable case interpretations of the ASME boiler and pressure vessel code as being acceptable.
Note: The ASME code specifies that persons installing boiler external piping by welding are required to possess the appropriate ASME credentials.
Note: Design and construction complying with Canadian standard CSA B51 is accepted by the Department under this section.
