What is BS EN 15471 - Determination of dissolved residues - High-temperature gravimetric method about?
BS EN 15471 specifies a method for determining the dissolved residual matter in liquefied petroleum gases (LPG), which remains after evaporation at 105 °C using the jet evaporation equipment described in EN ISO 6246.
The measurement range is from 20 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.
Who is BS EN 15471 - Determination of dissolved residues - High-temperature gravimetric method for?
BS EN 15471 on Determination of dissolved residues - High-temperature gravimetric method is useful for:
- Petroleum and natural gas industry 
- Testing houses and laboratories 
- Research institutes 
Why should you use BS EN 15471 - Determination of dissolved residues - High-temperature gravimetric method?
LPG is a petroleum gas that can be stored and/or handled in the liquid phase under moderate conditions of pressure and at ambient temperature, consisting predominantly of propane and butanes, with small proportions of propene, butenes and pentanes/pentenes.
From the analysis of a limited LPG sample size, the gravimetric method as specified in BS EN 15470 allows obtaining information on the potential origin of the residue (gasoil, lubricants, plasticizers, etc.), and also adjusting the samples allows determination of higher concentrations.
Compliance with BS EN 15471 helps you ensure the precision, accuracy, and safety in determining the dissolved residues using the high temperature gravimetric method.
