Scope

1.1 This specification covers the requirements for fully-formulated glycol base coolants for cooling systems of heavy-duty engines. When concentrates are used at 40 to 608201;% glycol concentration by volume in water of suitable quality, (see Appendix X1), or when prediluted glycol base engine coolants (50 volume8201;% minimum) are used without further dilution, they will function effectively during both winter and summer to provide protection against corrosion, cavitation, freezing, and boiling.

1.2 This specification is intended to cover the requirements for engine coolants prepared from virgin or recycled ethylene or propylene glycol.

Note 1: Committee D15 has not substantially studied the impact of using recycled glycols from sources such as:

• glycol bottoms

• polyester manufacturing waste

• aircraft and runway deicers

• medical waste

to prepare engine coolants. However, several serious cases of very poor performance have been reported and substantiated in heavy duty fleets when recycled glycols from sources such as above have been used to prepare engine coolants. Efforts are underway to more clearly define the purity requirements for glycols used to prepare engine coolants meeting this specification, whether from recycled engine coolants or other sources.

1.3 The coolants governed by this specification are categorized as follows:
