This document is an annex to EIA Engineering Bulletin SSB-1, Guidelines for Using Plastic Encapsulated Microcircuits and Semiconductors in Military, Aerospace and Other Rugged Applications (the latest revision). This document provides reference information concerning acceleration factors commonly used by device manufacturers to model failure rates in conjunction with statistical reliability monitoring. These acceleration factors are frequently used by OEMs in conjunction with physics of failure reliability analysis to assess the suitability of plastic encapsulated microcircuits and semiconductors for specific end use applications.
This SAE Recommended Practice applies to both Original Equipment Manufacturer (OEM) and aftermarket message-generating systems for light and heavy vehicles. The recommended practice covers both message prioritization and presentation (including simultaneous display of messages) for visual and auditory modalities. In addition, this recommended practice will consider temporal aspects of external events (e.g. merging into heavy traffic, time-to-collision) and their impact on temporal presentation and format (including multi-modal) of messages.
This SAE Standard provides test procedures and performance requirements for emergency warning devices (triangular shape), without self-contained energy sources, that are designed to be carried in motor vehicles and used to warn approaching traffic of the presence of a stopped vehicle, except for devices designed to be permanently affixed to the vehicle, and provides test procedures and performance requirements for protective containers for such emergency warning devices.
This specification covers established metric manufacturing tolerances applicable to seamless and welded thin-wall aircraft tubing of nickel, nickel alloys, and cobalt alloys ordered to metric dimensions. These tolerances apply to all conditions and are based on individual measurements, unless otherwise noted. The term "excl" is used to apply only to the higher figure of a specified range.
