A widely used material for lightning strike protection of CFRP structures within the aerospace industry is expanded metal foil (EMF). An issue with EMF is micro cracking of the paint, which can result in corrosion of the metal foil and subsequent loss of conductivity. Boeing researchers examined the issues of stress and displacement in the composite structure layup, which contribute to paint cracking caused by aircraft thermal cycling.

The focus of Operator Self-Verification is on traditional manufacturing operations, and applications can be made wherever traditional inspection is employed. The practices recommended in this document are intended to identify the basic elements and provide a "guideline " for structuring Operator Self-Verification programs within the aerospace industry; applicable to producers of commercial and military aircraft and weapons platforms, space vehicles, and all related hardware, software, electronics, engines and composite components. Operator Self-Verification programs are applied to improve the overall efficiency and product quality of processes considered mature, as judged by the implementing organization. Operator Self-Verification programs are not stand-alone processes, but augment existing quality management systems. The identified program elements are for voluntary implementation by the organization, and are not intended for contractual flow-down unless otherwise stipulated through contractual agreement.

This specification establishes the requirements for etch inspection of bare high strength low alloy steel parts having tensile strength of 180 ksi (1241 MPa) and higher and of carburized parts to detect overheating caused by abusive machining or grinding in the heat treated condition, and to detect localized discontinuous carburization. This process is not applicable to surface hardened steels produced by nitriding or carbonitriding. This process may remove 0.0001 to 0.0005 inch (2.5 to 12.7 micrometers) from the surface of the part.

This SAE Recommended Practice describes the vibration durability testing of a single battery (test unit) consisting of either an electric vehicle battery module or an electric vehicle battery pack. For statistical purposes, multiple samples would normally be subjected to such testing. Additionally, some test units may be subjected to life cycle testing (either after or during vibration testing) to determine the effects of vibration on battery life. Such life testing is not described in this procedure; SAE J2288 may be used for this purpose as applicable. Finally, impact testing, such as crash and pothole, is not included in this procedure.
