Overall Scope-The following topic are included in this report: Section 5-Material Selection Section 6-Production Considerations Section 7-Initial Structural Integrity Section 8-In-Vehicle Testing Section 9-Laboratory Testing The Material Selection section lists environmental factors and material properties which should be considered when determining appropriate fan material(s) for a given application. The Production Considerations section covers various aspects of machine selection@ mold design@ and process control. The Initial Structural Integrity section lists factors which should be considered in addition to those covered bySection 3of SAE J1390. The In-Vehicle Testing section lists factors which should be considered in addition to those covered bySection 4 of SAE J1390. The Laboratory Testing section addresses some test considerations and methods for non-metallic fans which differ from those used with metallic fans or which were not included in Section 5of SAE J1390. Purpose-This report exists to identify general methodology which addresses the areas of evaluation listed previously for injectionmolded nylon fans. It is envisioned that those working with other processes and/or materials can use SAE J1390 and this document as starting points in the development of structural analysis methodology pertinent to their particular combination(s).
