NPRD 1991 : 1991

This standard has replaced NPRD-3. Provides failure rate data for a wide variety of component types including electromechanical, mechanical and discrete electronic parts and assemblies. Also provides summary failure rates for numerous part categories by quality level and environment. Data represents a compilation of field experience in military, commercial and industrial applications and concentrates on items not covered by MIL-HDBK-217. Data tables include part descriptions, quality levels, application environments, point estimates of failure rate, data sources, number of failures, total operating hours and detailed part characteristics.
