4. INTRODUCTION
4.1 PURPOSE
This document contains design and procedural requirements for human spaceflight
equipment based on lessons learned and best practices.
4.2 BACKGROUND
JSC originally published its design and procedural requirements as bulletins circa 1964.
In 1971, these bulletins were combined into a single document, JSCM 8080. Since
then, JSC has, as needed, issued minor updates to the document, with major revisions
occurring in 1991 and 2005. Through the years, the document has undergone several
formatting and document number changes (e.g., JSCM 8080, JPR 8080.5, JSC-STD-
8080).
4.3 APPLICABILITY
These requirements are appropriate for the acquisition, design, development, test,
evaluation, operations, and sustaining engineering of any human spaceflight program,
project, spacecraft, system, or end item.
The requirements may be imposed via directive, specification, or agreement.
The requirements may be imposed individually (by referring to individual requirement
numbers) or wholly (by referring to the document number). If the requirements are
imposed wholly, it is appropriate to assess the applicability of individual requirements
(e.g., via an applicability matrix).
4.4 AUTHORITY
JPD 8080.2, JSC Design and Procedural Standards for Human Space Flight
Equipment.
4.5 APPLICABLE DOCUMENTS
The latest version of these documents apply unless otherwise specified. The
documents only apply when the referencing requirement applies (see Section 4.3), and
only to the extent specified in the referencing requirement. The referencing
requirements for each applicable document are listed in parenthesis following the
document name. Documents are grouped as follows and listed alphabetically by
document number within each group: law, NASA directives, NASA standards, non-
NASA government standards, and other standards.
JPR 1710.13, Design, Inspection, and Certification of Ground-Based Pressure Vessels
and Pressurized Systems (MP-13)
