IEEE 1156.4-1997

This standard will be designed for use in conjunction with P896.10 (Spaceborne Futurebus+ Profile Specifications) for specification of environmental withstand conditions applicable to spaceborne computer modules/circuit boards and all of the components attached to the modules. Environmental conditions for computer modules intended for use in space vehicles are not currently covered by existing standards. The space vehicle environment is characterized by thermal, mechanical, and electrical conditions not shared by office, industrial, shipboard, and aircraft environments. This environmental standard will promote development of cost-effective, high-reliability computer modules for space. New IEEE Standard - Inactive-Withdrawn. Fundamental information on minimum environmental withstand conditions for space electronics is provided. The intent is to achieve uniformity and reproducibility in the test conditions for all spaceborne computer modules that may make up larger systems and are purported to have a rated environmental performance level. The specifications pertain to both the natural and artificial environments to which spaceborne computer modules may be exposed. These conditions include, but are not limited to, thermal, mechanical, electrical, and radiation stresses.
