This standard establishes a method to calculate the vapour pressure of a given liquiefied petroleum gas (LPG) from its various components. By calculating the vapour pressure the frequently encountered difficulties of an actual measuring are avoided. The calculated vapour pressure determines the safety procedures, especially during transport for a given cargo of LPG.#,,#
