1.1''This guide covers general information, without specific limits, for selecting and evaluating pumpability characteristics of heat transfer fluids at both low and high temperature. This guide is a compendium of information and does not recommend a specific course of action. This guide provides additional information on pumpability topics found in companion guides for evaluating heat transfer fluids, Guides D5372 and D7665.

1.2''Pumpability of heat transfer fluids is dependent on both fluid properties and the design of the fluid handling system that stores and transports the fluid, and therefore presents a number of pumping options. This guide is considered particularly useful for identifying pumpability options. The listing of test standards and guides is not all-inclusive and additional standards and guides may be useful.

1.3''The values stated in SI units are to be regarded as standard.

1.4''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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Users of heat transfer fluids should be especially mindful of potential fire and explosion hazards.

1.5''This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
