Consolidate ice adhesion & accretion (and shedding) testing methods & define their applicability to real world icing conditions (need to define the attributes & processes)
Document the physics governing ice adhesion strengths & accretion behaviors
Define characteristics of ice formed in a range of atmosphere conditions
Propose testing methods & facility requirements capable of differentiating ice adhesion consistently
Define material properties affecting ice adhesion, including surface characteristics, preparation methods, and degradation
Definitions of terminologies (ice types, atmosphere conditions, accretion dynamics, strengths & applicability (shear, tensile etc.), passive ice protection vs. active ice protection, etc.)
Rationale: Ice adhesion strength is a function of types of ice (static, freezer, and impact ), substrate materials & preparation, and environment conditions (Temp, LWC, MVD etc.). It is difficult to obtain consistent results without defining the testing methods.
Difficult to establish correlation between ice adhesion strength and icing protection efficacy due to scattered results.
Lack of definition of testing apparatus & facility requirements & calibration standards
