Petroleum products - Test method for free water in liquefied petroleum gas by visual inspection
This test method covers the use of a pressure cylinder to determine the presence of free water in liquefied petroleum gas (LPG) by visual inspection below 0 °C.The LPG sample, in condition of saturated vapour pressure and containing dissolved water and / or free water, is clear and does not become cloudy making difficult to distinguish the two phases.As both LPG and water are colorless, it is rather difficult to observe a separation between the two liquid surfaces, only using a transparent container and under optimal lighting conditions it could be realized. Alternatively, the visibility of the water can be improved if it is frozen. In fact, ice is far less transparent than water and can be better observed.
