Standard Test Method for Boiling Point of Engine Coolants
The following bibliographic material is provided to assist you with your purchasing decision:
This test method establishes the standard procedures for the determination of the equilibrium boiling point of engine coolants. The equilibrium boiling point indicates the temperature at which the sample will start to boil in a cooling system under equilibrium conditions at atmospheric pressure. This method requires the use of the following apparatuses: round-bottom, short-neck, heat-resistant glass flask; water-cooled, reflux, glass-tube type condenser; grit No. 8 boiling stones of silicon carbide grains; partial immersion thermometer; and electric heating mantle as heat source. Specified amounts of the sample shall be boiled under equilibrium conditions at atmospheric pressure in the flask. The temperature of the liquid corrected for barometric pressure shall be the boiling point.
Scope
1.1 This test method covers the determination of the equilibrium boiling point of engine coolants. The equilibrium boiling point indicates the temperature at which the sample will start to boil in a cooling system under equilibrium conditions at atmospheric pressure.
Note 1—Engine coolants may also be marketed in a ready-to-use form (prediluted). This test procedure is applicable to diluted solutions as well as to concentrates.
Note 2—The procedure for obtaining a representative test sample of a coolant solution that contains an antileak additive is found in Test Method D 1176
1.2 The values stated in SI units are to be regarded as 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 and health practices and determine the applicability of regulatory limitations prior to use.
