The NASA/ESA Bilateral Safety and Product Assurance Requirements document is a joint National Aeronautics and Space Administration (NASA) and European Space Agency (ESA) document which describes all safety and product assurance requirements applicable to the ESA.

The contents of this document are derived from JESA 30000, section 9, Revision A, November 1993: NASA/STA Space Station Freedom Joint Program Definition and Requirements Document (JPDRD); Safety and Product Assurance Requirements, and SSP 30000, section 9, Revision F, September 1993; Space Station Program Definition and Requirements, section 9: Product Assurance Requirements.

The NASA/ESA Bilateral Safety and Product Assurance Requirements document is controlled after approval signatures, by the NASA Space Station Program Director and the ESA Program Manager. Both NASA and ESA herein mutually agree that the execution of this document is necessary for the effective and safe integration of the ESA Elements into the International Space Station.

APPENDIX(ES)

The ESA PA/Safety requirements are contained in the ESA project system requirements (e.g. COL-RQ-ESA-001, MS-RQ-ESA-004) and its associated ESA standards specification documents.

1.1 PURPOSE

This document establishes the joint hardware and software safety and product assurance (reliability, maintainability, and Quality Assurance) implementation requirements between NASA and ESA for the design, development, production, test, and operation of ESA vehicles, during the ISS program.

1.2 SCOPE

These safety and product assurance requirements are applicable to all flight equipment, Orbital Support Equipment (OSE), Flight Support Equipment (FSE), and certain Ground Support Equipment (GSE) (as specified herein) and related software supplied for the ESA projects.

1.3 MANAGEMENT APPROACH

The ESA Product Assurance implementation and Safety approach is covered by MS-RQ-ESA-004 and associated ESA standards specification documents.

Management of safety and product assurance shall include the following:

1.3.A Defining the major hardware and software safety and product assurance tasks and assuring that they are performed as integral parts of all phases of the program

1.3.B Evaluating the safety, reliability, maintainability, and quality of hardware, software, and operations through analyses, tests, reviews, and assessments

1.3.C Providing timely status reporting through periodic project reviews and as a part of overall project status reports

1.3.D Ensuring compatible safety and product assurance requirements for manufacturing, test, launch, and ground operations. For ESA, a safety and product assurance management plan shall be prepared by the project contractor. Safety and product assurance management shall have direct unimpeded access to the management level having full project responsibility.

1.4 RELATION TO OTHER PROGRAM REQUIREMENTS

1.4.1 PROGRAM REQUIREMENTS

The safety and product assurance analytical and verification requirements set forth in this document shall take precedence in cases of conflict with requirements contained in sub-tier documents. The safety and product assurance design requirements are contained in, for instance, in the applicable ESA segment specifications (e.g. SSP 41160, Segment Specification for the European Space Agency). The ESA requirements of MS-RQ-ESA-004 shall be the basis of the safety and product assurance program for the ESA projects and its interface to the ISS.

1.4.2 GSE HARDWARE AND SOFTWARE

NASA provided Safety and Mission Assurance (S&MA) analyses for GSE hardware and software used by ISS, but procured by other programs, need not be performed again when evaluation approved by the Product Groups and International Partners Project Office proposing the use of the GSE shows each analysis to be adequate to meet the intent of the applicable ISS analytical requirements document. All Critical Items and accepted risk hazards identified in these analyses must be baselined by the ISS.

1.5 MOTIVATION

Not Applicable.

1.6 INDEPENDENT EVALUATIONS FOR NASA OR THE INTERNATIONAL PARTNERS

ESA reserves the right to appoint independent representatives to assist in Safety and Product Assurance evaluation activities. These representatives will provide technical support to the applicable parent organization and determine effectiveness of and recommend improvements for Safety and Product Assurance activities.

NASA participation in such activities at ESA contractors will be subject to ESA agreement, on a case by case basis.

1.7 DATA EXCHANGE AGREEMENTS

All S&PA exchange data between NASA and ESA as agreed through the requirement of this document shall be identified in SSP 50127, NASA/ESA Data Exchange Agreement.

1.8 SAFETY AND PRODUCT ASSURANCE DATABASE

Safety and product assurance databases shall be established. The data transfer format will be defined in the SSP 50127, NASA/ESA Data Exchange Agreement.

1.9 MILESTONE REVIEWS

Safety and product assurance activities shall include supporting design reviews, and NASA and ESA design and readiness reviews. Participation in milestone reviews shall assure that safety and product assurance requirements are adequately considered.

1.10 DELEGATION OF AUTHORITY
