ASTM D is the major specification covering Aviation Gasoline. and it is anticipated that the Grade 91 will now be removed from ASTM D freeing up. This standard is issued under the fixed designation D; the . last published in Specification D–94 in the Annual Book of ASTM. ASTM D Standard Specification for Leaded Aviation Gasolines.

Used to power piston-engine ultralight aircraft.

Unleaded avgas is also available. Fuel dyes aid ground crew and pilots in identifying and asstm the fuel grades [12] and most are specified by ASTM D or other standards. Does This Make Sense? By Novemberthe company had built and received approval to produce fuel in its pilot plant.

ASTM D – 17a Standard Specification for Leaded Aviation Gasolines

Phased out in the late 20th satm. Each candidate fuel must meet a checklist of 12 fuel specification parameters and 4 distribution and storage parameters.

Samples are easily packaged and shipped to the labs on a global basis. This page was last edited on 16 Decemberat The new standard requires the 16, remaining USA sources of lead, which include lead smelting, airplane fuels, military installations, mining and metal smelting, iron and steel manufacturing, industrial boilers and process heaters, hazardous waste incineration, and production of batteries, to reduce their emissions by October Aztm Octane Number min Archived from the original on 10 July This does not constitute an insurmountable obstacle, but merely requires examination of the fuel system, ensuring adequate shielding from high temperatures and maintaining sufficient pressure in the fuel lines.

Retrieved 28 October FIRE Keep away from ignition sources. Send us a request APAC: In such fuels, the lead acts as a lubricant, coating the contact areas between the valve, guide, and seat. Retrieved 12 May Harmful or fatal if swallowed. Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world.


Fill sstm containers on the ground. Phase one testing is performed at the William J.

Its availability is very limited. Retrieved 3 April Motor Octane Number min Archived from the original on 7 May Archived from the original on 27 October However, the alloys used in aviation engine construction are d9100 for their durability and synergistic relationship with the protective features of lead, and engine wear in the valves is a potential problem on automotive gasoline conversions.

Despite assertions in the media that leaded avgas will be eliminated in the USA by at the latest date, the EPA confirmed in July that there astn no phase-out date and that setting one would be an FAA responsibility as the EPA has no authority over avgas. Avoid breathing the vapors and skin contact. Whether your business is local or global, we can ensure your products meet quality, health, environmental, safety, and social accountability standards for virtually any market around the world.

SuperCharge Octane Testing for Aviation Fuels

Retrieved from ” https: Given the progress already made on SF and GUL, the replacement time might be shorter than that estimate. Archived from the original on 2 D190 Supercharge Rating Performance No.

Retrieved 14 June They began x910 “Swift ” in [60] And patented several alternatives for non-alcohol based fuels which can be derived from biomass fermentation. In NovemberNational Air Transportation Association president Jim Coyne indicated that the environmental impact of aviation is expected to be a big issue over the next few years and will result in the phase out of LL because of its lead content.

Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.

Assurance Testing Inspection Certification. Note that properties critical to aviation use for example, vapour pressure and cleanliness are not controlled to the astk degree in automotive motor gasoline manufacture and handling.


TEL found in leaded avgas and its combustion products are potent neurotoxins that have been shown in scientific research to interfere with brain development in children. Retrieved 3 October New agriculture-based fuel revealed at Delphi Airport”. Retrieved 12 December This grade is generally available in most regions worldwide. Retrieved 8 April UL94 is an unleaded fuel, but as with all ASTM International unleaded gasoline specifications, a de minimis amount of unintentionally added lead is permitted.

The EPA responded with a notice of petition for rulemaking. Retrieved 11 September The Lycoming position is supported by aircraft type clubs representing owners of aircraft that would be unable to run on lower octane fuel. UL94 meets all of the same specification property limits as LL with the exception of a lower Motor octane number Fuel-injected engines in automobiles also usually have a “fuel return” line to send unused fuel back to the tank, which has the benefit of equalizing the fuel’s temperature throughout the system, further reducing the chance of vapor lock developing.

Unlike mogas, which has been formulated since the s to allow the use of platinum -content catalytic converters for pollution reduction, the most commonly used grades of avgas still contain tetraethyllead TELa toxic substance used to prevent engine knocking detonationwith ongoing experiments aimed at eventually reducing or eliminating the use of TEL in aviation gasoline.

This specification does not include all gasoline satisfactory for reciprocating aviation engines, but rather, defines the following specific types of aviation gasoline for civil use: Archived from the original on 1 November
