Frequently Asked Questions Regarding D1319 Dye Issue

    As of June 4, 2020

    What is ASTM D1319?

    • D1319 is one of about 13,000 voluntary consensus standards developed by members of ASTM International.
      • D1319’s title is “test method for hydrocarbon types in liquid petroleum products by fluorescent indicator adsorption.” It is a standardized test method used by refiners, labs, and others to measure the volume-percentage of aromatic hydrocarbons, olefins and saturates in petroleum products.
      • Members of the ASTM international committee on petroleum, liquid fuels, and lubricants (known as D02) include representatives from government agencies, industry, and labs. These members maintain, develop, and revise D1319, overseeing any changes to its technical content and status.
    • D1319’s Scope explains that this test method measures proportions of aromatics, olefins, and saturates.
      • An example of why this standard is used/important: According to the U.S. Federal Aviation Administration, high concentrations of aromatics in jet fuel can have adverse effects on turbine engine combustor durability while also producing more smoke and harmful particulates into the environment. D1655 and D7566 use testing of aromatics by D1319 as the referee method, but these specifications also cite D6379 as the accepted alternative. For more information, consult the current FAA Safety Airworthiness Information Bulletin (issued February 4, 2020).

    What is the current issue related to the dye used to conduct the test?

    • According to committee members, early in 2018, a key component of the Fluorescent Indicator Dyed Gel needed to perform Test Method D1319 became unavailable. An alternative dyed gel was substituted, but the reformulated dye gel was later found to be unsuitable for the analysis of jet fuel, diesel fuel and gasoline samples. This resulted in a shortage of the original formulation in the marketplace and led to a robust dialogue among oil companies, laboratories, and government agencies (e.g., FAA, U.S. Environmental Protection Agency). Many such stakeholders are involved in D02.

    Are D02 volunteer-members doing something about determining the suitability of the dye? If so, what?

    What are other test methods for aromatics, olefins, and saturates published by the committee?

    Users should consult the appropriate regulatory authorities having jurisdiction for specific compliance requirements.
