CSA - B51 S1-05 - Supplement No. 1 to B51-03, Boiler, Pressure Vessel, and Pressure Piping Code | Engineering360
CSA - B51 S1-05
This is the sixteenth edition of CSA B51, Boiler, Pressure Vessel, and Pressure Piping Code. It supersedes the previous editions published in 1997, 1995, 1991, 1986, 1981, 1975, 1972, 1969, 1965, 1960, 1957, 1955, 1951, 1945 and 1939.
Part 1 contains requirements for boilers, pressure vessels, pressure piping, and fittings. It is intended mainly to fulfill two objective: 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 2 contains requirements for high-pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles. It has been harmonized with International Organization for Standardization (ISO) Standard 11439:2000, Gas cylinders - High pressure cylinders for the on-board storage of natural gas as a fuel for automotive vehicles. In addition, the CSA subcommittee responsible for developing Part 2 has consulted with the American National Standards Institute (ANSI) committee responsible for developing ANSI Standard NGV2-2000, Basic Requirements for Compressed Natural Gas Vehicle (NGV) Fuel Containers. The members of these two committees are dedicated to harmonizing their Standards as far as circumstances allow.
Part 3 contains requirements for compressed natural gas refuelling station pressure piping systems and ground storage vessels. These requirements have been allotted a separate part of the Standard to emphasize the differences between them and the requirements in Part 1, and thereby to facilitate their application. To ensure that the design of new cylinders and refuelling stations are compatible, the filling limits specified in Clause 4.2 of Part 2 provide the besis for the design pressures specified in Clauses 6.1.4 and 6.1.5 of Part 3.
• Part 2 contains revised requirements concerning fire protection (Clause 6.9), design changes (Clause 6.16), failure to meet test requirements (Clause 6.17), and test methods (Clause 14).
(3) This publication was developed by consensus, which is defined by CSA Policy governing standardization - Code of good practice for standardization as "substantial agreement. Consensus implies much more than a simple majority, but not necessarily unanimity". It is consistent with this definition that a member may be included in the Technical Committee list and yet not be in full aggreement with all clauses of this publication.
