A new edition of CSA B625, developed by the Canadian Standards Association (CSA) Technical Committee on portable tanks for the transport of dangerous goods, has been published. Keep reading for highlighted changes to the standard and ways to view the standard in its entirety.

Published in May of 2020, CSA B625-20 “Portable Tanks for the Transport of Dangerous Goods,” will come into force on September 30, 2020, however, stakeholders may begin transitioning to these new standards at any time before this date.

Notable Changes to the Standard

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

• Alignment of technical requirements with the 20th edition of the UN Recommendations;
• 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; and
• 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.
