Product Code:SAE J1474
Title:Heavy-Duty Nonmetallic Engine Cooling Fans Material, Manufacturing,and Test Considerations
Issuing Committee:Cooling Systems Standards Committee
Scope:The following topics are included in this report:Section 2驴ReferencesSection 3驴DefinitionsSection 4驴Material SelectionSection 5驴Production ConsiderationsSection 6驴Initial Structural IntegritySection 7驴In-Vehicle TestingSection 8驴Laboratory TestingThe 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 by Section 3 of SAE J1390.The In-Vehicle Testing section lists factors which should be considered in addition to those covered by Section 4 of SAE J1390.The Laboratory Testing section addresses some test considerations and methods for nonmetallic fans which differ from those used with metallic fans or which were not included in Section 5 of SAE J1390.PurposeThis report exists to identify general methodology which addresses the areas of evaluation listed previously for injection-molded 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).
