Product Code:SAE AMS1626 Title:Desmutter, Aluminum, Liquid Issuing Committee:Ams J Aircraft Maintenance Chemicals And Materials Committee Scope:This specification covers materials in the form of a liquid used to remove smut from aluminum surfaces treated with etch-type oxidation and corrosion removers.Product Code:SAE AIR5909 Title:Validation and Verification of Fault Detection, Isolation and Prediction Algorithms for Engine Health Management Issuing Committee:E-32 Aerospace Propulsion Systems Health Management Scope: This document applies to the verification and validation (V&V) of EHM technologies as applied to gas turbine engines and propulsion systems. Its purpose is to define leading V&V approaches and required data sets that can be applied with regard to gas turbine engine monitoring systems and explain its application and limitations. This document will also provide guidelines for specific V&V metrics applications that can be implemented in engine condition monitoring environments. It also includes some examples.
