Annotation

This specification establishes the requirements for ethylene glycol, propylene glycol, 1,3 propanediol, and glycerin base heat transfer fluids (HTF) used in heating and air conditioning (HVAC) systems. When concentrates are used at up to 65% concentration by weight in water, or when prediluted heat transfer fluids (30% by weight minimum) are used without further dilution, they will function effectively to provide protection against freezing, and corrosion. The HTFs governed by this specification are categorized according to the primary base of freeze depressant used: I (ethylene glycol), II (propylene glycol), III (1,3-propanediol), and IV (glycerin).
