Final answer:
The CSA B51 standard covers ferrous and non-ferrous materials with notch toughness requirements, including aluminum piping systems. It relates to boilers, pressure vessels, and pressure piping systems in Canada.
Step-by-step explanation:
The Canadian standard that includes ferrous and non-ferrous materials with notch toughness requirements and includes aluminum piping systems is CSA B51. This standard, often referred to as the Boiler, Pressure Vessel, and Pressure Piping Code, sets out the requirements for the design, fabrication, installation, inspection, and testing of boilers, pressure vessels, pressure fittings, and piping systems in Canada. It is comprehensive and addresses various materials, including requirements for aluminum piping systems.
The other options mentioned serve different purposes: CSA W47.1 focuses on the certification of companies for fusion welding of steel, CSA G40.21 pertains to structural quality steels, and CSA W59 deals with welded steel construction. Therefore, for questions related to materials with notch toughness and aluminum piping, CSA B51 is the relevant standard.
