1.1 This specification covers the requirements for ethylene glycol, propylene glycol, 1,3 propanediol as well as 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. 1.2 The fluids described in this specification are not appropriate for use in systems where internal combustion engines (gasoline, diesel, or CNG/LPG) are used. 1.3 The heat transfer fluids governed by this specification are categorized as follows by the primary base of freeze depressant used:
1.4 Heat transfer fluids meeting this specification shall be tested and fully comply with requirements listed in Table 1. Note 1: This specification is based on the knowledge of the
performance of heat transfer fluids prepared from new or virgin
ingredients. This specification shall also apply to heat transfer
fluids prepared using materials generated from recycled or
reprocessed ingredients, provided that these ingredients meet the
requirements of Specifications E1177 and D7388 for Glycols and Specification
D7640 for
Glycerin.
Note 2: This specification addresses concentrated inhibited
glycols and glycerol that will be mixed with water for use in
various climates and prediluted heat transfer fluids (HTF) that are
factory-blended with purified water. A table of estimated freeze
protection temperatures at appropriate dilutions is provided in
Appendix X1.
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.6 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 and health practices and determine the applicability of regulatory limitations prior to use. 1.7 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. |
