This document is intended for use as one of the elements of project solicitation for complex systems requiring a systematic evaluation of safety hazards and mitigating measures. The Managing authority may identify, in the solicitation and system specification, specific system safety engineering requirements to be met by the Developer. These may include risk assessment and acceptance criteria, unique classifications and certifications, or mishap reduction needs unique to their program.
GEIA Handbook 859 provides implementation guidance for ANSI/EIA 859, with discussions of applications of the standard's principles, tools, examples, and case studies. Handbook 859 is organized according to the lifecycle of data management and covers activities from the pre-RFP stage through records disposition. It also provides annexes on topics which apply at multiple stages in the lifecycle, such as protection of data, continuous improvement and knowledge management.
Programs may inadvertently introduce Pb-free elements (including piece part finish, printed wiring board finish, or assembly solder) if careful coordination between buyer and supplier is not exercised. For example, piece part manufacturers may not always change part numbers to identify Pb-free finishes, especially if the previous tin-lead (Sn/Pb)-finished piece part has been discontinued. Detailed examination of piece parts and documents at receiving inspection while crucial, may not be sufficient to identify Pb-free piece parts.
Note: Pb-free technology can impact any program regardless of whether the program itself is exempt or bound by environmental regulations. The industry conversion to Pb-free solder technology may affect an aerospace program in one or both of the following ways: 1.
Packaged Electronic Devices. Electronic Devices are defined as any packaged electrical, electronic, electro-mechanical (EEE) item, or assemblies using such items. This standard is intended to ensure that adequate reliability is achieved for devices in user applications after long term storage. Users are encouraged to request data from suppliers to this specification that demonstrates a successful storage life requested by the user. This standard is not intended to address built-in failure mechanisms that would take place regardless of storage conditions.
