It is one of the oldest check methods under the jurisdiction of ASTM Committee D02, relationship from the time when it was still referred to because the Engler distillation. Because the test technique has been in use for such an prolonged interval, an incredible number of historical knowledge bases exist for estimating end-use sensitivity on products and processes.
5.2 The distillation (volatility) characteristics of hydrocarbons have an important effect on their safety and performance, particularly in the case of fuels and solvents. The boiling range gives information on the composition, the properties, and the conduct of the gas during storage and use. Volatility is the most important determinant of the tendency of a hydrocarbon mixture to supply probably explosive vapors.
5.Three The distillation characteristics are critically essential for each automotive and aviation gasolines, affecting starting, heat-up, and tendency to vapor lock at high working temperature or at high altitude, or both. The presence of high boiling point parts in these and other fuels can considerably have an effect on the diploma of formation of solid combustion deposits.
5.4 Volatility, because it impacts fee of evaporation, is a vital think about the appliance of many solvents, notably those used in paints.
5.5 Distillation limits are often included in petroleum product specifications, in business contract agreements, process refinery/management purposes, and for compliance to regulatory rules.
1. Scope
1.1 This test methodology covers the atmospheric distillation of petroleum products and liquid fuels utilizing a laboratory batch distillation unit to find out quantitatively the boiling vary traits of such products as light and center distillates, automotive spark-ignition engine fuels with or without oxygenates (see Note 1), aviation gasolines, aviation turbine fuels, diesel fuels, biodiesel blends as much as 20, marine fuels, special petroleum spirits, naphthas, white spirits, kerosines, and Grades 1 and a couple of burner fuels.
Notice 1: An interlaboratory research was performed in 2008 involving eleven completely different laboratories submitting 15 data units and 15 totally different samples of ethanol-gas blends containing 25 volume, 50 volume, and 75 volume ethanol. The outcomes indicate that the repeatability limits of these samples are comparable or inside the revealed repeatability of the strategy (with the exception of FBP of 75 ethanol-gas blends). On this foundation, it can be concluded that Take a look at Technique D86 is applicable to ethanol-gas blends similar to Ed75 and Ed85 (Specification D5798) or other ethanol-gas blends with better than 10 volume ethanol. See ASTM RR:D02-1694 for supporting information.2
1.2 The take a look at technique is designed for the analysis of distillate fuels; it isn’t applicable to merchandise containing appreciable portions of residual materials.
1.Three This test technique covers both guide and automated instruments.
1.Four Except in any other case noted, the values stated in SI models are to be regarded as the usual. The values given in parentheses are provided for data only.
1.5 WARNING—Mercury has been designated by many regulatory companies as a hazardous material that can cause central nervous system, kidney and liver injury. Mercury, or its vapor, could also be hazardous to well being and corrosive to supplies. Caution must be taken when dealing with mercury and mercury Petroleum Product manufacture containing merchandise. See the applicable product Materials Safety Data Sheet (MSDS) for particulars and EPA’s website—http://www.epa.gov/mercury/faq.htm—for additional data. Users ought to be aware that selling mercury and/or mercury containing merchandise into your state or nation may be prohibited by regulation.
1.6 This standard doesn’t purport to handle all of the safety issues, if any, associated with its use. It’s the accountability of the person of this normal to ascertain acceptable safety and well being practices and determine the applicability of regulatory limitations prior to make use of.
1.7 This worldwide normal was developed in accordance with internationally acknowledged principles on standardization established in the choice on Rules for the event of International Standards, Guides and recommendations issued by the World Trade Organization Technical Obstacles to Trade (TBT) Committee.
2. Referenced Documents (purchase individually) The paperwork listed below are referenced inside the subject standard however should not offered as part of the standard.
