试验方法 用压力液体比重计测定轻烃类物质的密度或相对密度的标准试验方法。轻烃类物质(包括LPG液化石油气)的密度和相对密度,常常用于运输、存储和规范等用途。 Test Method Density and relative density measurements of light hydrocarbons, including LPG, are used for transportation, storage and regulatory purposes. The measurement is made by floating a thermohydrometer in a sample that has been introduced into a pressure cylinder.
