Appendix A. Definitions

Agency. The National Aeronautics and Space Administration (NASA).

Applicable Documents. Citations consisting of documents cited in the body of the document that contain provisions or other pertinent requirements directly related to and necessary for the performance of the activities specified by the document. (Source: NPR 1400.1, NASA Directives Procedural Requirements.)

Consensus. General agreement, but not necessarily unanimity, and includes a process for attempting to resolve objections by interested parties, as long as all comments have been fairly considered, each objector is advised of the disposition of his or her objection(s) and the reasons why, and the consensus body members are given an opportunity to change their votes after reviewing the comments. (Source: OMB Circular No. A-119, Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities.)

Handbook. A handbook is a guidance document that provides engineering information; lessons learned; possible options to address technical issues; classification of similar items, materials, or processes; interpretative direction and techniques; and any other type of guidance information that may help the Government or its contractors in the design, construction, selection, management, support, or operation of systems, products, processes, or services. (Source: MIL-STD-967, Defense Handbooks, Format and Content.) Also, a how-to document containing procedural, technical, engineering, or design information or data about materials, processes, practices, or methods. Although NASA handbooks may contain "shall" statements, they are not intended to be requirements documents. Handbooks, or portions thereof, containing procedural or process requirements may be cited in contract, program, and other Agency documents .

Impractical. Includes circumstances when the use of voluntary consensus standards would fail to serve the Agency's program needs; would be infeasible; or would be inadequate, ineffectual, or inconsistent with the Agency's mission. (Source: OMB Circular No. A-119, Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities.)

NASA-Endorsed Technical Standards. Proven technical standards that have been identified and recommended by NASA Headquarters offices for particular types of applications and should be considered first for use in developing technical requirements for current and future NASA programs and projects.

NASA Technical Standards. Consist of technical standards, specifications, and handbooks developed and approved by NASA Headquaters Offices for Agencywide use. NASA technical standards are assigned a prefix of "NASA-STD-," "NASA-SPEC-," or "NASA-HDBK-," respectively, to the unique document number.

Other Government Agency Standards. Technical standards product documentation originated and published by Government agencies other than NASA (e.g., military (MIL), Federal (FED), Department of Defense (DoD)).

Performance Standard. A standard that states requirements in terms of required results with criteria for verifying compliance but without stating the methods for achieving required results; may define the functional requirements for the item, operational requirements, and/or interface and interchangeability characteristics; also may be viewed in juxtaposition to a prescriptive standard. (Source: OMB Circular No. A-119, Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities.)

Prescriptive Standard. A standard which may specify design requirements such as materials to be used, how a requirement is to be achieved, or how an item is to be fabricated or constructed. (Source: OMB Circular No. A-119, Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities.)

Specification. A document that prescribes, in a complete, precise, verifiable manner, the requirements, design, behavior, or characteristics of a system or system component. (Source: NPR 7123.1, NASA Systems Engineering Processes and Requirements.)

Standard or Technical Standard. Common and repeated use of rules, conditions, guidelines, or characteristics for products or related processes and production methods and related management systems practices; the definition of terms, classification of components; delineation of procedures; specification of dimensions, materials, performance, designs, or operations; measurement of quality and quantity in describing materials, processes, products, systems, services, or practices; test methods and sampling procedures; or descriptions of fit and measurements of size or strength. (Source: OMB Circular No. A-119, Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities.)

Tailoring. The process used to adjust or seek relief from a prescribed requirement to accommodate the needs of a specific task or activity (e.g., program or project). The tailoring process results in the generation of deviations and waivers depending on the timing of the request. (Source: NPR 7120.5, NASA Space Flight Program and Project Management Requirements.))

Technical Authority. Part of NASA's system of checks and balances that provides independent oversight of programs and projects in support of safety and mission success through the selection of individuals at delegated levels of authority. These individuals are the Technical Authorities. Technical Authority delegations are formal and traceable to the Administrator. Individuals with Technical Authority are funded independently of a program or project. (Source: NPR 7120.5, NASA Space Flight Program and Project Management Requirements.)

Technical Requirements. Requirements that discuss the design, performance, operational parameters, and constraints of equipment and systems. These are requirements that would typically be contained within a system or equipment specification. Requirements are identified by the word "shall." (Source: NPR 1400.1, NASA Directives Procedural Requirements.)

Use. Incorporation of a standard in whole, in part, or by reference for procurement purposes, and the inclusion of a standard in whole, in part, or by reference in regulation(s). (Source: OMB Circular No. A-119, Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities.)

Voluntary Consensus Standards. Standards developed or adopted by voluntary consensus standards bodies, both domestic and international, that include provisions requiring that owners of relevant intellectual property have agreed to make that intellectual property available on a non-discriminatory, royalty-free, or reasonable royalty basis to all interested parties. (Source: OMB Circular No. A-119, Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities.)

Voluntary Consensus Standards Bodies. Domestic or international organizations that plan, develop, establish, or coordinate voluntary consensus standards using agreed-upon procedures and are defined by the following attributes: (1) openness, (2) balance of interest, (3) due process, (4) an appeals process, and (5) consensus. (Source: OMB Circular No. A-119, Federal Participation in the Development and Use of Voluntary Consensus Standards and in Conformity Assessment Activities.)
