- Scope
5.1 The freezing point of an engine coolant indicates the coolant freeze protection.
5.2 The freezing point of an engine coolant may be used to determine the approximate glycol content, provided the glycol type is known.
5.3 Freezing point as measured by Test Method D1177 or approved alternative method is a requirement in Specifications D3306 and D6210.
5.4 This test method provides results that are equivalent to Test Method D1177 and expresses results to the nearest 0.1°C with improved reproducibility over Test Method D1177.
5.5 This test method determines the freezing point in a shorter period of time than Test Method D1177.
5.6 This test method removes most of the operator time and judgement required by Test Method D1177.
1.1 This test method covers the determination of the freezing point of an aqueous engine coolant solution.
1.2 This test method is designed to cover ethylene glycol base coolants up to a maximum concentration of 608201;% (v/v) in water; however, the ASTM interlaboratory study mentioned in 12.2 has only demonstrated the test method with samples having a concentration range of 40 to 608201;% (v/v) water.
Note 1: Where solutions of specific concentrations are to be tested, they shall be prepared from representative samples as directed in Test Method D1176. Secondary phases separating on dilution need not be separated.
Note 2: The products may also be marketed in a ready-to-use form (prediluted).
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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. Some specific hazards statements are given in 7.3.
