The U. S. Army Electronic Proving Ground USAEPG, Fort Huachuca, Arizona, conducted an engineering test of Protective Helmet SPH-4 to determine its technical performance, engineering adequacy, and safety characteristics. Thirteen test items were bench tested at USAEPG from July through September 1969. White Sands Missile Range provided support and facilities for the temperature-shock, fungus, and humidity subtests the remaining environmental subtests were conducted at Fort Huachuca. One deficiency fungus and five shortcomings were found during the engineering test program. These failures did not affect the operational performance of the SPH-4. It is concluded that the technical performance, engineering adequacy, and safety characteristics of the SPH-4 are satisfactory. The massive fungal growth found on the SPH-4 components restricts its use in tropical areas. It is recommended that the deficiency and shortcomings be corrected and the SPH-4 be considered suitable for service testing. Author
