Product Code:SAE AS5692
Title:Arc Fault Circuit Breaker (Afcb), Aircraft, Trip-Free Single Phase 115 Vac, 400 Hz - Constant Frequency
Issuing Committee:Ae-8b1 Protective Devices Committee
Scope:The primary function of this specification is to cover the general requirements for manual reset trip-free arc fault/thermal circuit breakers for use in aircraft electrical systems conforming to MIL-STD-704. As a secondary function, this specification may possibly cover the general requirements for AFCBs for use in primary vehicles, other than aircraft, when mounted directly to the structure.Product Code:SAE AMS5132
Title:Steel Bars, 0.90 1.30c
Issuing Committee:Ams E Carbon And Low Alloy Steels Committee
Scope:This specification covers a high-carbon steel in the form of bars. This product has been used typically for dowels and other parts requiring close tolerances, but usage is not limited to such application.
