(Specification)Standard Specification for Stop-Leak Additive for Engine Coolants Used in Light Duty Service
Standard Specification for Stop-Leak Additive for Engine Coolants Used in Light Duty Service
ABSTRACT
This specification covers the requirements of a stop-leak additive to function effectively in automobile and light duty service. The stop-leak is intended to seal small leaks in engine cooling systems without adversely affecting heat transfer and fluid flow. The hole plugging capability, and foaming tendency of the stop-leak additive shall be tested to meet the requirements prescribed.
SCOPE
1.1 This specification covers the requirements of a stop-leak additive to function effectively in automobile and light duty service. The stop-leak is intended to seal small leaks in engine cooling systems without adversely affecting heat transfer and fluid flow.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This 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.
