ASTM D1119 – Standard Test Method for Percent Ash Content of Engine Coolants
Description:
Significance and Use
5.1 This test method is designed to aid in identifying types of coolants. While the ash is primarily due to the inorganic inhibitors used, it is not a measure of the total inhibitor concentration because of the loss of organic inhibitors.
5.2 An ash content greater than that stated in Specification D3306 may indicate a salt-based product.
Scope
1.1 This test method covers the determination of ash content after ignition of commercial engine coolants and antirusts, as packaged or after use.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
