ASTM D7665-10 - 1.10.2010
 
Significance and Use

The significance of each test method depends 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.

 
1. Scope

1.1 This guide covers general information, without specific limits, for selecting standard test methods for evaluating heat transfer fluids for quality and aging. These test methods are considered particularly useful in characterizing biodegradable water free heat transfer fluids in closed systems.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
