The ASTM D3060-94 (2013) standard test method is used to determine the pressure drop rate of compressed gas-propelled products. This method is suitable for all products that use pre-pressurized vessel Encasement, providing rapid and repeatability test results. During the test, dispensing conditions in actual use are simulated to ensure that subtle differences in valves and actuators are evaluated, and the final equilibrate pressure in the vessel is correlated with the amount of product dispensed. This test method helps to optimize product performance and Encasement design.
