適用范圍：This Standard specifies a method, for determining the residual matter in liquefied petroleum gases (LPG),which remains after evaporation at 105 ℃. This material represents those products deposited in car LPGvaporizers that are subject to a temperature equal to or greater than the boiling temperature of water. Therange of determination extends from 50 rog/kg to 100 mg/kg. Higher concentrations can be determined byadjusting the sample size.The precision data of the method have been determined from 20 mg/kg to 100 mg/kg, with samples amountfrom 100 g to 50 g.This method has been developed as a potential replacement of the commonly used method EN ISO 13757 [1],The advantages of the method are that a small quantity of LPG (100 mi) is required.NOTE An alternative European Standard, EN 15470 [2], with the same scope, specifies a gas chromatographymethod with slightly better fidelity.
