SSP 30426D, SPACE STATTION EXTERNAL CONTAMINATION CONTROL REQUIREMENTS - INTERNATIONAL SPACE STATION ALPHA (21 JAN 1994)

SSP 30426D, SPACE STATTION EXTERNAL CONTAMINATION CONTROL REQUIREMENTS - INTERNATIONAL SPACE STATION ALPHA (21 JAN 1994)., his document establishes the requirements that control the release of neutral gases and particulate into the external environment to ensure the maximum utility of the Space Station (SS) capabilities. This document contains the requirements that limit the contributions to the external, gaseous, and particulate environment due to the presence of the SS and its hardware. Requirements applicable to Space Shuttle delivery of SS hardware and experiments to space are included. The requirements are derived from previous experience bases and should be achieved at minimum Program costs if they are considered early in design. These requirements reflect the maximum contributions to the neutral particulate and gas environment above the natural environment that can be tolerated in order to make unrestricted measurements for all presently know attached users except some atmospheric composition studies. Requirements as stated are applicable for Space Station hardware including payloads.
