Scope

This document spécifiés a method for the determination of the dissolved residual matter, also known as evaporation residue, in liquéfiéd petroleum gases (LPG), by gas chromatography in the range of (10 to 600) mg/kg (ppm mass).

This test method quantifiés soluble organic compounds (hydrocarbon materials), sometimes called ‘evaporation residue’, which can be present in liquéfiéd petroleum gases and which are substantially less volatile than the LPG product, i.e. with a boiling point between 174 °C and 522 °C (C10 to C40). Higher boiling materials, or materials that adhere permanently to the chromatographic column, will not be detected.
