BS EN 15470:2017 specifies a method for determining the dissolved residual matter in liquefied
petroleum gases (LPG), in the range of 40 mg/kg to 100 mg/kg. Higher concentrations can be determined by
adjusting the sample size.
The dissolved residue is the amount of organic compounds which is detectable by gas chromatography after
evaporation of the sample at ambient temperature and then in an oven at 105 ?C.
This method is not suitable for detecting solid materials or for possibly high molar mass polymers
(>1 000 g/mol).
From the analysis of a limited LPG sample size (50 g to 75 g) this method allows obtaining information on
the potential origin of the residue (gasoil, lubricants, plasticizers, etc.).
The precision data of the method have been determined from 20 mg/kg to 100 mg/kg. For a higher content
of residue, the precision has not been tested.
NOTE An alternative European Standard, EN 15471 [1], specifies a gravimetric method.
