WIP
AS6171/11A
This method outlines the requirements, capabilities, and limitations associated with the application of Design Recovery for the detection of counterfeit electronic parts including: Operator training; Sample preparation; Imaging techniques; Data interpretation; Design/functional matching; Equipment maintenance and; Reporting of data. The method is primarily aimed at analyses performed by circuit delayering and imaging with a scanning electron microscope or optical microscope; however, many of the concepts are applicable to other microscope and probing techniques to recover design data. The method is not intended for the purpose of manufacturing copies of a device, but rather to compare images or recover the design for determination of authenticity. If AS6171/11 is invoked in the contract, the base document, AS6171 General Requirements shall also apply. SAE Counterfeit Defect Coverage Tool

Isolation and Corrosion Protection of Dissimilar Materials, Carbon Composite Structure Repair

2018-08-24
WIP
ARP4118B
This SAE Aerospace Recommended Practice (ARP) provides methods and guidelines for isolating dissimilar repair patch materials from carbon composite structure during a repair operation. These procedures are applicable to any repair procedure for carbon fiber reinforced plastic parts in which the repair patch is a metallic alloy that can form a galvanic cell with carbon in the presence of moisture or other electrolytes. The principal patch materials addressed are aluminum, titanium, and stainless steel. The procedures are primarily concerned with bolted repairs that introduce the most severe, potential corrosion problem but bonded repairs are also considered. The procedures are also applicable to repairs involving reinstallation of metallic inserts into a carbon fiber reinforced plastic part. Fiberglass and aramid fiber reinforced plastics do not have galvanic reactions with other materials, and the procedures outlined herein are, therefore, not essential with these materials.
