Full Description

1.1This specification covers the general, physical, chemical, and performance requirements for Supplemental Coolant Additives (SCAs) at a precharged level in the cooling systems of heavy-duty engines.

Note 1:After precharging, SCAs are customarily used periodically to service cooling systems at ¹/₄to ¹/₃the precharged dosage to compensate for additives lost through dilution and depletion.

1.2The SCA products meeting this specification are intended for use with water, with recommended dilutions of coolant concentrates, with prediluted engine coolants, or to upgrade the performance of light-duty engine coolants to meet the heav-duty requirements of Specification D6210. Engine coolant products shall be of the low-silicate type and, if ethylene glycol based, shall meet Specification D4985. Propylene glycol base low-silicate type coolant products may also be used, if these materials meet the chemical and performance requirements of Specification D4985.

1.3The SCA concentrate, before dissolution, may be in either liquid, solid, or slurry form. The form is as agreed upon between the manufacturer and the user.

1.4The values stated in SI units are to be regarded as standard. The inch-pound units in parentheses are approximate equivalents provided for information only.

1.5This 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.

1.6This 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.
