1.1 This specification covers one grade of 100 % middle distillate fuel oil (no residual contamination), Grade No. 2-LTD, for use in off-road applications requiring long-term storage stability. This grade of middle distillate fuel is similar to Specification D 975, Grade No. 2-D but with additional properties specified to provide storage stability, as well as other properties required by specific end use applications. This grade is intended for off-road applications such as military marine use (non-aviation gas turbine engines, compression ignition/diesel engines, and other non-automotive applications), emergency generators (military or commercial), as well as any other uses that require storage stable middle distillate fuel.

1.2 This specification, unless otherwise provided by agreement between the purchaser and the supplier, prescribes the required properties of middle distillate fuel at the time and place of delivery. Nothing in this specification shall preclude observance of federal, state, or local regulations that may be more restrictive.

1.3 During handling and use of all middle distillate fuels, the generation and dissipation of static electricity can create fire and explosion hazards. For more information on this subject see Guide D 4865.

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

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 requirements prior to use.
