The document outlines the guaranteed specifications for LPG propane and butane tests, detailing various parameters including specific gravity, vapor pressure, and allowable content levels of propane, ethane, and other compounds. It specifies the necessary ASTM test methods for measuring these properties, as well as maximum thresholds for factors like oil stain, corrosion, and sulfur content. Both propane and butane must pass certain criteria to ensure quality and compliance with industry standards.
