Standard Specification for Low Silicate Ethylene Glycol Base Engine Coolant for Heavy Duty Engines Requiring a Pre-Charge of Supplemental Coolant Additive (SCA)
|Publication Date:||10 April 1998|
|ICS Code (Refrigerants and antifreezes):||71.100.45|
1.1 This specification covers the requirements for a low silicate ethylene glycol-base engine coolant concentrate for cooling systems of heavy duty engines. When used at 40 to 60 % concentration by volume in water of suitable quality, (see Appendix X1), it will function effectively during both winter and summer to provide protection against corrosion, freezing, and boiling.
NOTE 1--This specification is based on the knowledge of the performance of engine coolants prepared from new or virgin ingredients. See X1.1.4 for additional information.
1.2 Coolant concentrates meeting this specification require an initial charge of a supplemental coolant additive (SCA) and require 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 manufacturer or vehicle manufacturer. If they provide no instructions, follow SCA supplier's recommended instructions.
1.3 The values stated in SI units are to be regarded as 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.
