DIN EN ISO 3405:2011-04

This document (EN ISO 3405:2011) 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), in collaboration with Technical Committee ISO/TC 28 "Petroleum products and lubricants". The responsible national committee is NA 062-06-81 AA, Mirror Committee of CEN/TC 19 "Gaseous and liquid fuels, lubricants and related products of petroleum, synthetic and biological origin" at the Petroleum, Fuels, Lubricants and Related Products Standardization Committee (NMP). This International Standard specifies a laboratory test method, utilizing either manual or automated equipment, for determining the distillation characteristics of light and middle distillates derived from petroleum and having initial boiling points above 0 °C and end points below approximately 400 °C. Light distillates are typically automotive engine petrols, automotive engine petrols with up to 10 % (V/V) ethanol and aviation petrols. Middle distillates are usually aviation turbine fuels, kerosenes, diesel, diesel with up to 20 % (V/V) fatty acid methylesters (FAME), burner fuels and marine fuels that have no appreciable quantities of residua. The distillation characteristics (volatility) of hydrocarbons are extremely significant in terms of safety and usability, above all for fuels and solvents. The distillation characteristics provide important information regarding composition and behaviour during storage and use, and the evaporation rate is an essential factor for the use of many solvents. In most requirements for petroleum-based distillates, maxima or minima are specified for the distillation characteristics, in order to monitor final usability and to limit the formation of vapours which could form explosive mixtures with the air or which could be released into the atmosphere as VOCs (volatile organic compounds).
