Oil-fired furnaces are required to be tested in accordance with which standard?

The correct standard for testing oil-fired furnaces is ASTM E 1509. This standard outlines the necessary procedures for evaluating the performance and safety of oil-fired appliances, ensuring they operate efficiently and reliably. ASTM E 1509 specifically addresses the combustion performance, energy consumption, and other critical parameters that are vital for the safe operation of these furnaces. Adhering to this standard helps in establishing a basis for performance measurement that is recognized within the industry, ensuring that the equipment meets safety and environmental regulations.

The other standards listed, such as UL 127, UL 1618, and UL 730, pertain to different types of appliances and performance criteria that do not specifically focus on oil-fired furnaces. For instance, UL standards primarily focus on safety aspects and construction of appliances but may not cover the combustion testing and efficiency evaluations as comprehensively as ASTM E 1509 does for oil-fired systems.
