ASTM D3305

ASTM D3305 is a standard testing method that measures how much sulfur dioxide gas is emitted when a material is burned, specifically asphalt and other roofing products. This test helps assess the environmental impact and safety of these materials by determining their potential to release sulfur dioxide, a gas that can cause air pollution and health issues. It ensures that roofing and asphalt products meet regulatory requirements for emissions, promoting safer and more environmentally responsible construction practices.
