2024 Ontario Building Code Guide: Referenced Standards for Material Compliance in London
Sarah's Expert Insight
OBC Compliance Specialist
"The 2024 updates to the ASTM and ASSE standards specifically address the long-term durability of plumbing and structural components against the high humidity of Muskoka and the rapid freeze-thaw cycles seen in London and Oakville. Ensuring your contractor uses materials that strictly meet these referenced codes is the difference between a project that lasts decades and one that requires premature, costly remediation."
In the evolving landscape of Ontario construction, staying compliant with the 2024 Building Code Compendium is essential for safety and structural integrity. As empcontracting.ca Inc. your construction contractor in London, Ontario, we prioritize these referenced standards in Division B – Part 1, Table 1.3.1.2. to ensure every project meets the highest benchmarks.
Plumbing Performance and Safety Standards
The OBC references several ASSE, ASME, and CSA standards to regulate plumbing efficiency and user safety across residential and commercial builds.
Water Temperature and Pressure Control
- ASSE 1016 / ASME A112.1016 / CSA B125.16: Performance requirements for automatic compensating valves in showers and tub combinations (Section 7.2.10.7.(1)).
- ASSE 1070 / ASME A112.1070 / CSA B125.70: Standards for water temperature limiting devices to prevent scalding (Section 7.2.10.7.(2)).
- ASSE 1037 / ASME A112.1037 / CSA B125.37: Performance requirements for pressurized flushing devices (Section 7.2.10.8.(1)).
Structural Steel and Corrosion Protection (ASTM Standards)
ASTM standards ensure that the steel components of a building can withstand environmental stressors, particularly in the varied climates of Southern Ontario.
Galvanization and Protective Coatings
- ASTM A123 / A123M: Specifications for hot-dip galvanized coatings on iron and steel products (Table 5.9.1.1. and 9.20.16.1.).
- ASTM A153 / A153M: Standards for zinc coatings on hardware, critical for exterior structural fasteners (Section 9.23.2.4.(2)).
- ASTM A653 / A653M: Requirements for zinc-coated or galvannealed steel sheets used in structural applications.
Piping and Tubing Specifications
The selection of piping materials is dictated by rigorous ASTM metrics to prevent leaks and system failures:
- ASTM B42: Standards for seamless copper pipe.
- ASTM A312: Specifications for seamless and welded stainless steel pipes (Section 7.2.6.10.(1)).
- ASTM A53 / A53M: Requirements for black and hot-dipped zinc-coated welded and seamless steel pipes.
