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.【中国标准分类号】: E31【国际标准分类号】: 75_160_20【页数】: 12P.;A4【正文语种】: 英语
