Doplňujúce informácie
| Significance and Use |
|
4.1 This test method will generally distinguish between non-aqueous coolants that are definitely deleterious from the corrosion standpoint and those that are suitable for further evaluation. However, the results of this test method cannot stand alone as evidence of satisfactory corrosion inhibition. The actual service value of an engine coolant formulation can be determined only by more comprehensive bench, dynamometer, and field tests. |
| 1. Scope |
|
1.1 This test method covers a simple beaker-type procedure for evaluating the effects of non-aqueous engine coolants on metal specimens under controlled laboratory conditions (see Appendix X1). Note 1: For more information on aqueous and non-aqueous engine
coolants, see (Refs 1.2 The values stated in SI units are to
be regarded as standard. The values given in parentheses after SI
units are provided for information only and are not considered
standard.
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. |
