Most notable changes

The most notable changes that appear in the new edition of this standard are summarized below:

  • revised quality manual requirements to allow for harmonized documentation requirements with CSA B620 for those facilities also registered under the safety standard for Highway and TC portable tanks
  • restructuring of registration requirements to simplify the number of registration types
  • limiting the pressure vessel code acceptability of foreign-approved tanks to the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1 or 2. Foreign-approved tanks built after 2018 to the ASME Boiler and Pressure Vessel Code, Section VIII, Division 1 and used for Class 2 or toxic inhalation hazard dangerous goods will need to be U-stamped
