The members of these two committees are dedicated to harmonizing their standards as far as circumstances allow. In addition, the CSA Subcommittee responsible for developing Part 2 has consulted with the American National Standards Institute (ANSI) committees responsible for developing CSA/ANSI NGV 2-2016, Compressed natural gas vehicle fuel containers, and CSA/ANSI HGV 2-2014, Compressed hydrogen gas vehicle fuel containers. It has been harmonized with International Organization for Standardization (ISO) Standard 11439:2013, Gas cylinders - High pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles. Part 2 contains requirements for high-pressure cylinders for the on-board storage of natural gas, blends of natural gas and hydrogen (hydrogen blends), and hydrogen as fuels for automotive vehicles.

It is intended mainly to fulfill two objectives: first, to promote safe design, construction, installation, operation, inspection, testing, and repair practices and second, to facilitate adoption of uniform requirements by Canadian jurisdictions.

Part 1 contains requirements for boilers, pressure vessels, pressure piping, and fittings.

In keeping with CSA Group’s goal of harmonizing its standards with those of other countries to the greatest extent possible, CSA’s Technical Committee on Boilers and Pressure Vessels and its Subcommittees have, in the course of developing this Standard, worked closely with the National Board of Boiler and Pressure Vessel Inspectors in the United States and with the American Society of Mechanical Engineers (ASME) committees responsible for producing the National Board Inspection Code and ASME’s Boiler and Pressure Vessel Code. Product Information CSA B51, Boiler, pressure vessel, and pressure piping code (nineteenth edition) We are happy to announce that the full B51: Boiler, pressure vessel, and pressure piping code and B52: Mechanical refrigeration code are now available for purchase as a print product from our eStore.

To support safety in the Power Engineering and thermal utilities industries, we have established a resale agreement with CSA Group to distribute the full codes. In June, we announced that the Extract of CSA Standards would be discontinued due to changes in CSA Group’s content licencing. Full CSA code books now available for purchase through PanGlobal
