ASTM D6210-98a

Standard Specification for Fully-Formulated Ethylene-Glycol-Base Engine Coolant for Heavy-Duty Engines

SCOPE
1.1 This specification covers the requirements for a fully-formulated ethylene-glycol-base coolant for cooling systems of heavy-duty engines. When concentrates are used at 40 to 60% ethylene-glycol concentration by volume in water of suitable quality, (see Appendix X1), or when prediluted ethylene-glycol base engine coolants (50% volume, % minimum) are used without further dilution it 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 glycol.
1.3 Both concentrated and prediluted products are covered by this specification.
1.4 Coolant concentrates meeting this specification do not require any 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.
1.5 This specification does not cover extended service internal coolants.
1.6 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.7 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.
