New Test Method for Measurement of Decomposition Products in Phosphate Ester Fluids by Linear Sweep Voltammetry

1. Scope

The scope of the Committee shall be the promotion of knowledge and the promulgation of standard specifications, classifications, test methods, practices, guides, and terminology in the following technical fields:
Liquid fuels derived from: petroleum or the liquefaction of coal, shale, oil sands, or other naturally occurring materials; liquefied petroleum gas (LPG) and other compressed liquefied fuels; liquid fuels derived from biological materials ('biofuels'); synthesized liquid fuels (also known as renewable or alternative fuels) and oxygenates as fuels or components thereof. Such liquid fuels encompass fuels used for aviation, automotive, burner, diesel, gas turbine, and marine services.
Lubricants derived in whole or in part from petroleum and non-petroleum sources, including synthetics (such as ester lubricating oils), biological, or naturally occurring (mined) materials;
Hydraulic fluids whether derived in whole or in part from petroleum or from other sources;
Liquid hydrocarbons (including liquefied petroleum gas (LPG), and mixtures of hydrocarbons, for chemical and special uses, and fuel products derived therefrom;
Petroleum coke, industrial carbons, and industrial pitches derived in whole or in part from petroleum liquids;
Petrolatum and petroleum waxes;
Additives and other substances which affect the product characteristics of fuels, lubricants, and other products within the scope of the Committee.
Also included within the scope of the Committee shall be the promotion of knowledge and the promulgation of standards on the environmental persistence (biodegradation), ecotoxicity, and bioaccumulation of the products indicated in Section 2.1.
Specifically excluded from the scope of the Committee are standards related to the following technical areas:
Gaseous fuels, including natural gas (including LNG and CNG), hydrogen and manufactured gases such as water gas;
Aromatic and naphthenic hydrocarbons containing six or more carbon atoms, and used in chemical manufacture;
Road and paving materials, bituminous waterproofing and roofing materials;
Paint thinners, solvents;
Electrical insulating materials.
The work of this Committee shall be coordinated with other ASTM International committees and with organizations having mutual interests.

The benefits of measuring alkylphenols are: monitor hydrolysis, monitor weaker acid, phosphate ester stability, and quality control of new/virgin fluids. The alkylphenols that are generated are contaminants and not antioxidants. The current standards listed below are for measuring aromatic phenols and aromatic amines antioxidants. New Standard Test method was proposed. Once that is done, it is recommended to make the necessary changes to D6224 so it can reference this standard.

The title and scope are in draft form and are under development within this ASTM Committee.
