ASTM International Standard Test Method for pH of Engine Coolants and Antirusts ASTM D1287-25

1.1 This test method covers the determination of the pH of unused engine coolants, insulation and heat transfer fluids, antirusts, and used or unused aqueous dilutions of the concentrated products. Note 1: Antirusts in solid form are not included in this test method. Note 2: It is believed that this procedure gives all the information required for determining the pH of samples of engine coolant or antirust likely to be encountered. Should additional information on pH determinations be needed, reference should be made to Test Method E70. 1.2 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. 1.3 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.
