DIN EN 15470:2008 Liquefied petroleum gases - Determination of dissolved residues - High temperature Gas chromatographic method; English version of DIN EN 15470:2008-02
This European Standard 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 that are detectable by gas chromatography after
evaporation of the sample at ambient temperature and then in an oven at 105 ℃.
This method is not suitable for detecting solid materials or for possibly high molecular weight polymers
(> 1 000 g/mol).
The advantages of this method are that a small quantity of LPG (50 g to 75 g) is required and the qualitative
data available may indicate the origin of the residues (gas-oil, lubricants, plasticizers, etc.).
This method has been developed as a potential replacement of the commonly used method described in
EN ISO 13757 [1], but is safer and more environmentally friendly. In addition, this new method is more
accurate.
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, but remains of lesser interest as typical specifications are in the
range of 20 mg/kg to 100 mg/kg.
NOTE An alternative European Standard, EN 15471 [2], specifies a gravimetric method, which has the same scope
and slightly worst fidelity data.
