This SAE Aerospace Standard (AS) further defines the requirements for a delegation process identified in Aerospace Quality Management System (AQMS) standards (i.e., AS9100, AS9110, AS9120). This standard establishes minimum requirements for the delegation of product verification to an organization's suppliers; outlining requirements for the initial delegation (qualification/selection), maintenance, and removal/withdrawal of delegations.
The growing role of electronics and software is altering the design process, requiring a greater focus on validation and verification, particularly to meet the stringent demands of off-highway environments.
Three SAE standards are to be incorporated in EPA regulations, including refrigerant identification, built-in or via USB on hand-held units, incorporated in requirements for recovery/recycle/recharge equipment. There's also a standard for testing internal heat exchangers in development.
Program Management/Systems Engineering Guidelines for Managing the Transition to Lead-Free Electronics
This handbook is designed to assist a program in assuring the performance, reliability, airworthiness, safety, and certifiability of product(s), in accordance with GEIA-STD-0005-1, “Performance Standard for Aerospace and High Performance Electronic Systems Containing Pb-free Solder”. Please note that the program manager, and managers of systems engineering, Supply Chain and Quality Assurance (along with their respective organizations), and the appropriate enterprise authority need to work together in ensuring that all impacts of Pb-free technology insertion are understood and risks mitigated accordingly. Herein “program management (or manager), supplier chain management (or manager), quality assurance management (or manager) and systems engineering management (or manager) and/or the appropriate enterprise authority” shall be defined as “responsible manager” throughout the remaining document (see Section 3, Terms and Definitions).

Method for Preliminary Assessment about Lifetime Estimation of Electronic Components in Hybrid and EV Applications
Abstract Increasing demand of Electric and Hybrid vehicles questions more about Reliability and Lifetime of electronic circuits associated with them. It is very important for a hardware circuit designer to evaluate if module will last the expected lifetime. This paper elaborates the methods and steps to find the expected lifetime of critical components; and to decide whether Hybrid Power Electronics Unit (PEU) will meet the OEM requirements on lifetime. Accelerated thermal stress method is used to determine the required High Temperature Operational Life (HTOL) hours for given thermal profile of Hybrid vehicle passenger car in driving (8,000Hrs), charging(30,000Hrs) and total lifetime (38000Hrs ≈ 15Years). Example calculation of required HTOL hours against expected lifetime for critical component from Hybrid ECUs is explained in this paper. Also inclusions and exclusions of this method in evaluating lifetime assessment are also discussed here.

This document covers the process to be applied to Key Characteristics (KC’s) - as defined in AS9103 - on parts, part families or processes as defined by the purchaser or producer. These requirements apply to any product feature, process, or key process input that influences tha ability of the producer to meet or exceed the customer variation management requirements. KC’s include product and process features that benefit from variation management and have a positive impact on Quality, Cost, Delivery and performance of the finished product by the purchaser or their suppliers.. Design characteristics not included within the scope include those on commercially standard parts (for which the customer does not hold design authority) Suppliers who outsource parts with customer key characteristics are responsible for the flow-down of this standard.….
