Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Type of information:
experimental study
Adequacy of study:
key study
Study period:
1 (reliable without restriction)
according to guideline
other: SH/T 0065 Practice for Sampling and Preparing Aqueous Solutions of Engine Coolants ASTM D1177 Standard Test Method for Freezing Point of Aqueous Engine Coolants.
Principles of method if other than guideline:
This test method involves the determination of the time-temperature curve prior to freezing and the determination of the horizontal or flattened portion of the freezing curve. The freezing point is taken as the intersection of projections of the cooling curve and the freezing curve. If the solution supercools, the freezing point is the maximum temperature reached after supercooling.
