    Significance and Use

    5.1 In general, wherever the possibility exists of water getting mixed with products/material (covered under 1.1) the results obtained by this test method will indicate the degree to which corrosion of iron components can be expected.

    5.2 Test also determines the antirust properties of products/material (covered under 1.1) in preparation for the various stages through which the tested product may pass prior to or during its transport through a pipeline.

    5.3 Test results are also meant to show whether or not the dosage levels and type of iron corrosion inhibitor added to a product/material (covered under 1.1) is sufficient for achieving the desired protection of affected assets such as storage tanks, process lines, and shipment systems.

    1. Scope

    1.1 This test method covers an accelerated laboratory and field procedure for the determination of corrosion of iron, in the presence of water, on samples such as gasoline and gasoline blended with 10 % ethanol, E10 (Specification D4814); gasoline-blend components (except butane); diesel fuel and biodiesel B5, except Grade No. 4-D (Specification D975); biodiesel B6 to B20 (Specification D7467); diesel-blend component such as light cycle-oil; No.1 fuel oil, No.2 fuel oil (Specification D396); aviation turbine fuel (Specification D1655).

    1.2 The values stated in SI units are to be regarded as the standard.

    1.2.1 Exception—Values in parentheses are for information only.

    1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
