SPH Helmet Copies
The look, shape, and design of Gentex’s SPH series of helicopter helmets are frequently copied. The copies, sold under various trade names, look a great deal like genuine SPH helmets, but often contain parts not made according to current specification drawings for the SPH-4B (PS-0020) or the SPH-5 (PS-0028 or PS-0058).
Genuine Gentex SPH-5 commercial helicopter helmets are made according to the latest revision to SPH-5 specification, PS-0058. They are manufactured in Gentex’s ISO-9001 qualified factory with Defense Logistics Agency oversight, and tested in an AS-9000C certified laboratory.
Other Specifications
MIL-H-43925D is an inactive SPH-4B military specification introduced in 1988 and declared inactive by the Department of Defense in 2000. It has been replaced by SPH-4B specification PS-0020, which has more protective impact requirements and additional requirements for lateral earcup impact and shell penetration.
ANSI Z90.1 is an American National Standard for Motor Vehicular Users Protective Headwear. It was issued in 1971 but is no longer an active ANSI standard. Since it is a motor vehicle helmet standard, it does not include all the requirements and tests to which helicopter helmets are subjected. Military specifications often refer to ANSI Z90.1 is used to describe test procedures. Current helicopter helmets, such as the HGU-56/P and SPH-5 are more protective than required by ANSI Z90.1.
MIL-DTL-87174A is the military specification for the Air Force’s HGU-55/P fixed-wing helmet. The specification is current, but it does not require the level of protection needed for helicopter helmets.
