: While this test doesn't perfectly simulate the exact conditions inside a massive storage tank, it provides a consistent level of measurement that is independent of the operator or location. Regulatory Compliance : Many terminals and transport vessels require an ASTM D5705 "Can Test" before they will accept a product for discharge. Vapor vs. Liquid Phase Testing It is important to distinguish between vapor phase (ASTM D5705) and liquid phase testing (such as ASTM D7621 ASTM D6021 Vapor phase results (D5705) are primarily used for health and safety assessments of the immediate atmosphere. Liquid phase results are used for product quality control ASTM D5705 is the industry standard for measuring
