Time-Triggered Ethernet

AS6802A (Current)2/14/2023

This SAE Aerospace Standard (AS) defines a fault-tolerant synchronization strategy for building and maintaining synchronized time in a distributed system of end systems and switches (we use the term “end system” for data terminal equipment (DTE), as specified in IEEE 802.3), which can be used to support communication among these components for traffic, which may have different levels of time criticality. In particular, the standard defines algorithms for clock synchronization, clique detection, startup, and restart. These algorithms have been designed to allow scalable fault-tolerance and provide self-stabilization mechanisms. Time-triggered Ethernet supports the design of communication systems with mixed time criticality in which several applications of mixed time criticality share a single physical network. In particular, an Ethernet network can be used to transfer frames in a time-triggered mode (synchronous communication) and non-time-triggered modes (asynchronous communication as

Hydrogen Fuel Quality Screening Test of Chemicals for Fuel Cell Vehicles

J3219_202206 (Current)

6/13/2022

The outcome of this TIR is to establish proton exchange membrane (PEM) testing methods and characterization of chemicals used in HRS, during operation and maintenance that can influence the performance of commercial PEM fuel cell vehicles. Hydrogen quality standards such as SAE J2719 provide list of contaminants with maximum impurity levels that ensure safe operation of fuel cell vehicles. These contaminants are primarily from the hydrogen production. Less attention in these quality standards were given to the contaminants generated from the installation, operation and maintenance of HRS. Common chemicals used during HRS operation are refrigerants, lubricants, etc., and during HRS installation and maintenance are solvents cleaning agents, lubricants, etc. Some of these chemicals are found to have adverse impacts on PEM fuel cells. The development of testing methods and characterization of chemicals in this report are based on similar methods used in SAE J2719 although the approach in
