This Standard specifies a method, for determining the residual matter in liquefied petroleum gases (LPG),
which remains after evaporation at 105 °C. This material represents those products deposited in car LPG
vaporizers that are subject to a temperature equal to or greater than the boiling temperature of water. The
range of determination extends from 50 mg/kg to 100 mg/kg. Higher concentrations can be determined by
adjusting the sample size.
The precision data of the method have been determined from 20 mg/kg to 100 mg/kg, with samples amount
from 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 ml) is required.
NOTE An alternative European Standard, EN 15470 [2], with the same scope, specifies a gas chromatography
method with slightly better fidelity.
WARNING — Use of this method involves hazardous materials and operations. It is the responsibility
of the user to establish appropriate safety and health precautions. All handling must be performed in a
fume hood.
