DIN EN 16423:2014-02

This document has been prepared by Technical Committee CEN/TC 19 "Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin", the secretariat of which is held by NEN (Netherlands). The responsible national committee is Working Committee NA 062-06-31 AA "Anforderungen an Flüssiggase" ("Requirements for liquified gases") of the Standardization Committee for Petroleum, Fuels, Lubricants and Related Products (FAM) of the Materials Testing Standards Committee (NMP) at DIN. This European Standard specifies a method for the determination of the dissolved residual matter, also known as evaporation residue, in liquefied petroleum gases (LPG), by gas chromatography in the range of (10 to 600) mg/kg (ppm mass). This test method quantitatively determines soluble organic compounds (hydrocarbon materials), sometimes called "evaporation residue", which can be present in liquefied petroleum gases and which are substantially less volatile than the LPG product, namely 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, are notdetected.
