Product Code:SAE ARP461
Title:Synchros
Issuing Committee:A-4 Aircraft Instruments Committee
Scope:In order to ease the equipment design engineer's problem and at the same time provide a basis for comparing measurements by manufacturer and user this recommended practice sets up standard test procedures for acceptance testing. These conditions and the basic tests to which the characteristics refer are grouped in Section 2 and compose a complete list of defining characteristics of the synchro. Specifications written around synchros have specified certain necessary characteristics for production acceptance testing, such as null voltage and accuracy, under test conditions and techniques that are mainly and properly concerned with accuracy and the shortest possible test time. These characteristics are inherently degraded when the synchro is operating for a period of time at other than room temperature. In synchros this degradation is a factor of high importance

Title:Deembrittlement Verification Test
Issuing Committee:
Scope:This standard outlines test methods and practices which can detect embrittlement of steel parts. It is a process control or referee verification test. The risk of embrittlement of steel is minimized by using best practices in the finishing/coating process. One such practice is described in SAE/USCAR-5, Avoidance of Hydrogen Embrittlement of Steel.【英文标准名称】:Specificationforautomaticchange-overcontactorsforemergencylightingsystems
