ASTM D5372 Guide for Evaluation of Hydrocarbon Heat Transfer Fluids
1. Scope
1.1 This guide provides information, without specific limits, for selecting standard test methods for testing heat transfer fluids for quality and aging. These test methods are considered particularly useful in characterizing hydrocarbon heat transfer fluids in closed systems.

3. Terminology
3.1 Definitions of Terms Specific to This Standard:
3.1.1 heat transfer fluid - a petroleum oil or related hydrocarbon material which remains essentially a liquid while transferring heat to or from an apparatus or process. Small percentages of nonhydrocarbon components such as antioxidants and dispersants can be present.
4. Significance and Use
4.1 The significance of each test method will depend upon the system in use and the purpose of the test method as listed under Section 5. Use the most recent editions of ASTM test methods.
