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.
² The background for this standard was developed by a questionnaire circulated by ASTM-ASLE technical division L-VI-2 and reported in Lubrication Engineering, Vol 32, No. 8, August 1976, pp. 411–416.
