D15.30 - Industrial Heat Transfer Fluids

SIGNIFICANCE AND USE
4.1 This test method will generally distinguish between HTFs that are definitely deleterious from the corrosion standpoint and those that are suitable for further evaluation. However, the results of this test method cannot stand alone as evidence of satisfactory corrosion inhibition. The actual service value of an HTF formulation can be determined by more comprehensive evaluation and field tests, agreed between customer and supplier.
SCOPE
1.1 This test method covers a simple beaker-type procedure for evaluating the effects of heat transfer fluids (HTF) on metal specimens under controlled laboratory conditions. Fluids tested under this method are specifically designed for heating and air conditioning (HVAC) systems.  
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in 10.1.7.2, 10.1.7.3, 10.1.7.4, and A1.1.6.  
1.4 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.

ABSTRACT
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).
