This specification covers the requirements for fully-formulated glycerin base coolants for cooling systems of heavy-duty engines. It also notes that the requirements of the coolant concentrate or prediluted coolant include protection in operating engines against cavitation corrosion and scaling of internal engine hot surfaces.

1.1This specification covers the requirements for fully-formulated glycerin base coolants for cooling systems of heavy-duty engines. When concentrates are used at 40% to 60% glycerin concentration by volume in water of suitable quality (see ), or when prediluted glycerin base engine coolants (50 volume % min) are used without further dilution, they will function effectively during both winter and summer to provide protection against corrosion, cavitation, freezing, and boiling.
1.2This specification is intended to cover the requirements for engine coolants prepared from virgin glycerin.
Note 1:This specification is based on the knowledge of the performance of engine coolants prepared from new or virgin ingredients that comply with Specification .
1.3The coolants governed by this specification are categorized as follows:
1.4Coolant concentrates meeting this specification do not require addition of supplemental coolant additive (SCA) until the first maintenance interval when a maintenance dose of SCA is required to continue protection in certain heavy duty engine cooling systems, particularly those of the wet cylinder liner-in-block design. The SCA additions are defined by and are the primary responsibility of the engine manufacturer or vehicle manufacturer. If they provide no instructions, follow the SCA supplier's instructions.
1.5The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard.
1.6This 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.
1.7This 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.
