Method to measure the filtration performance of SCR/Urea filters

2021-01-27
WIP
J3245
The purpose of this SCR filter test method is to provide standardized methods for evaluation the filter characteristics of the SCR filter by bench test methods. This, combined with data obtained from application test, maybe used to establish standards of performance for filters when tested by these standard methods. Many variation in requirements of filtration to protect the SCR supply equipment on vehicles and variations in operational conditions make it difficult to specify meaningful “in-service” performance standards by which a filter may be judged. By the use of these standard test methods, test conditions are always the same, and comparison of the laboratory performance of filters may be made with a high degree of confidence. Once the requirement of a particular application are known, performance standards for suitable filters may be established by these test methods, and adequacy of performance of filters for the job may be determined.

Design and Test Recommendations for Dielectric Strength and Insulation Resistance for Line Replaceable Units

2021-04-26
WIP
ARP5769
Scope: This Aerospace Recommended Practice (ARP) provides guidelines for specifying dielectric withstanding strength and insulation resistance design and test requirements for aircraft line replaceable units (LRU's) used within a flight control and/or a utility system. 1.1 Purpose The testing is intended to verify that an LRU can operate safely at its rated voltage and withstand momentary over potentials due to switching, troubleshooting testing, surges, etc.. The testing is also intended to verify adequate design margin of the insulation system and detect workmanship problems.
