This method was adapted from NATO STANAG 4370, AECTP 300, Method 315.
1.1 Purpose
The purpose of this Method is to determine the ability of materiel to withstand:
- a. The effects of moisture phase changes between liquid and solid, in or on materiel, as the ambient temperature cycles through the freeze point.
b. The effects of moisture induced by transfer from a cold-to-warm or warm-to-cold environment.
1.2 Application
This Method is applicable to materiel that will experience one or more excursions through the freeze point while wet or in the presence of moisture (free water or vapor). See paragraph 2.1 for specific examples. For additional information, see Part Three, paragraph 5.9.
1.3 Limitations
This Method is not intended to evaluate the effects of low temperature, thermal shock, rain, or icing. These may be determined using Methods 502.7, 503.7, 506.6, and 521.4, respectively.
