Which standard might govern the use of asphalt in roofing applications?

The standard that governs the use of asphalt in roofing applications is ASTM D312. This standard specifically deals with the specifications for asphalt used in roofing materials, covering various aspects such as composition, physical properties, and performance requirements. It is essential for ensuring that the asphalt meets the necessary criteria for durability, adhesion, and weather resistance when used in roofing systems.

Understanding the relevance of this standard is crucial for the proper selection and application of asphalt in roofing, as it guarantees the material's performance characteristics in real-world scenarios. This contributes significantly to the longevity and effectiveness of roofing systems, providing better protection against the elements.

Other standards listed, while relevant to other materials or aspects of construction, do not specifically govern asphalt in roofing. For example, ASTM D313 discusses asphalt roofing cement, particularly its consistent adhesion capabilities, while ASTM E84 pertains to testing the surface burning characteristics of building materials. Lastly, ASTM C578 focuses on rigid cellular polystyrene thermal insulation, which doesn't relate directly to the asphalt itself but to insulation materials used in roofing assemblies.
