(Specification)Standard Specification for Prediluted Aqueous Ethylene Glycol Base Low-Silicate Engine Coolant (50 Volume % Minimum) for Heavy-Duty Engines Requiring an Initial Charge of Supplemental Coolant Additive (SCA) (Withdrawn 2000)
Standard Specification for Prediluted Aqueous Ethylene Glycol Base Low-Silicate Engine Coolant (50 Volume % Minimum) for Heavy-Duty Engines Requiring an Initial Charge of Supplemental Coolant Additive (SCA) (Withdrawn 2000)
SCOPE
1.1 This specification covers the requirements for a prediluted aqueous ethylene glycol base low-silicate engine coolant (50 volume percent minimum) for cooling systems of heavy-duty engines. When used without further dilution, this product will function effectively during both summer and winter to provide protection from corrosion, freezing at least to -36.7°C (-34.0°F), and boiling at least to 108°C (226°F).
1.2 Prediluted coolant meeting this specification requires both an initial charge of a supplemental coolant additive (SCA) and regular maintenance doses of an SCA to continue the protection in certain operating 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 or vehicle manufacturer. If they provide no instructions, follow the SCA supplier's recommended instructions.
1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.4 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.
