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.

In demonstrations held in JulyGUL performed better than LL that just meets the minimum specification and equal to average production LL. The EPA’s own studies have shown that to prevent a measurable decrease in IQ for children deemed most vulnerable, the standard needs to be set much lower, to 0.

Archived from the original PDF on There are other classification systems for military turbine fuel and diesel fuel. 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.
Certain equipment or conditions of use may permit a wider, or require a narrower, range of characteristics than is shown by this specification. The company eventually intends to produce the fuel from renewable biomass feedstocks, and aims to produce something competitive in price with LL and currently available alternative fuels.

Some of the lower-powered — horsepower or 75— kilowatts aviation engines that were developed in the late s qstm designed to run on unleaded fuel and on LL, an example being the Rotax Archived from the original on 26 February Additives such as TEL help to control detonation dd910 provide lubrication. Confusion can be caused by the terms Avtur and AvJet being used for jet fuel. However, the alloys used in aviation engine construction are chosen 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.

Archived from the original on 28 February Archived from the original on 20 May Under a federal court order to set a new standard by 15 Octoberthe EPA cut the acceptable limits for atmospheric lead from the previous standard of 1. Don’t Panic On Avgas”. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.
The production economics of this new fuel have not been confirmed but it is anticipated that it will cost at least as much as LL. The reduced pressure in the line can cause the more volatile components in automotive gasoline to flash into vapor, forming bubbles in the fuel line and interrupting fuel flow.

Teledyne Continental Motors, Inc. Care must be taken by small airplane pilots to select airports with avgas on flight planning.
UL94 is not intended to be a full replacement for LL but rather is designed to be a drop-in replacement for aircraft with lower-octane-rated engines, such as those that are approved for operation on Grade 80 avgas or lowerUL91, or mogas.

S910 United States Environmental Protection Agency EPA has noted that exposure to even very low levels of lead contamination has been conclusively linked to loss of IQ in children’s brain function tests, thus providing a high degree of motivation to eliminate lead and its compounds from the environment.
At an EPA public consultation held in June on the new standards, Andy Cebula, the Aircraft Owners and Pilots Association ‘s executive vice president of government affairs stated that general aviation plays a valuable role in the USA economy and any changes in lead standards that would change the current composition of avgas would have a “direct impact on the safety of flight and the very future of light aircraft in this country”.
