MIL-PRF-372E § - Freezing Stability Test

We perform testing according to Military Specification MIL-PRF-372E; this test measures the stability of a weapons cleaning solvent under freezing conditions. The cleaner is placed in a stoppered tube and frozen at -54 °C for 16 hours, followed by 8 hours at 25 °C. This is repeated three times, and then the test tube is allowed to stand at 25 °C for 16 hours. The sample is then examined for any sign of separation.
