Update with administrative changes, 1400 compliance, added under Policy (3) (a)-(c) policy statements; updated Attachment B and added an Attachment C: References. |
a. It is NASA policy to:
(1) Control measurement processes to ensure the accuracy of measurement results affecting safety and mission success. Functions and conditions requiring measurement controls are identified in Attachment A.
(2) Establish and maintain traceability of measurement results by an unbroken chain of calibrations through the National Institute of Standards and Technology (NIST), or an institution recognized by NIST through international agreements, to the International System of Units (SI) when such units have been established.
(3) Control the accuracy, reliability, and use of Measuring and Test Equipment (MTE) through the use of a calibration system compliant with a calibration standard listed below and applicable requirements of SAE AS9100, subject to the clarifications and modifications provided in Attachment B of this NASA Policy Directive (NPD).
(a) ANSI/NCSL Z540.1-1994 (R2002), Calibration Laboratories and Measuring and Test Equipment - General Requirements.
(b) ANSI/NCSL Z540.3-2006 (R2013), Requirements for the Calibration of Measuring and Test Equipment.
(c) ISO/IEC 17025: 2005, General Requirements for the Competence of Testing and Calibration Laboratories.
a. This NPD is applicable to NASA Headquarters and NASA Centers, including Component Facilities and Technical and Service Support Centers. This language applies to the Jet Propulsion Laboratory, a Federally Funded Research and Development Center, other contractors, grant recipients, or parties to agreements only to the extent specified or referenced in the appropriate contracts, grants, or agreements.
b. Paragraph 1.a(3) above does not apply to NASA acquisition contracts and Center institutional service contracts initiated prior to promulgation of this NPD. Retroactive application of this policy to existing contracts is at the discretion of the applicable NASA program manager or Center Director based on an evaluation of risk related to the retention of previously existing requirements versus implementation of this NPD revision.
c. Waivers to the requirements of this NPD are to be processed in accordance with NASA-STD-8709.20.
d. The requirements of this NPD are in addition to, not in replacement of, requirements specified by official local, State, or Federal regulatory bodies. Where conflicts exist, requirements specified by regulatory bodies take precedence.
e. In this NPD "shall" denotes a mandatory action, "may" or "can" denotes discretionary privilege or permission, "should" denotes a good practice and is recommended, but not required, "will" denotes expected outcome, and "are/is" denotes descriptive material.

a. The Chief, Safety and Mission Assurance shall:
(1) Provide interpretive guidelines, training resources, and tools for the implementation of the requirements of this NPD.
(2) Designate a responsible Center with delegated Metrology and Calibration Program responsibilities. Delegated responsibilities include development of policy and procedural requirements, issuance of guidance documents, and deployment of tools/resources facilitating Center Metrology and Calibration Program implementation.
(3) Authorize the charter and resources for the NASA Metrology and Calibration Working Group (MCWG). The MCWG serves as a collaborative forum for the development of Agency requirements, guidance, and tools for effective metrology/calibration program implementation.
b. Center Directors shall:
(1) Establish, implement, and monitor metrology and calibration requirements to implement the policy provided in paragraph 1 of this NPD for Center institutional functions delineated in Attachment A of this NPD.
(2) Provide institutional support for program/project manager implementation of this NPD at their respective NASA Centers and component facilities.
(3) Designate a qualified representative to the NASA MCWG to provide Center representation and input at MCWG meetings, workshops, and other designated activities.
(4) Provide for managerial oversight and documentation of Center measurement control processes, including the management of MTE calibration intervals and related recall programs.
c. Program/project managers shall:
(1) Establish, implement, and monitor metrology and calibration requirements to implement the policy provided in paragraph 1 of this NPD for program/project management functions delineated in Attachment A of this NPD.
(2) Coordinate metrology and calibration efforts among Centers,
component facilities, and other locations providing program/project
support.
None.
Compliance with the requirements contained in this NPD is continuously monitored by the Centers and by the SMA Technical Authority. Compliance may also be verified as part of selected cycle reviews, and by assessments, reviews, and audits of the requirements and processes defined within this NPD.
NPD 8730.1B, Metrology and Calibration, dated April 29, 2004.
A.1. Testing, qualification, certification, and/or acceptance measurements of flight hardware, ground support equipment, test systems, or other flight-related products.
A.2. Measurements essential to the safety of personnel and the public or for the protection of Government or private property, including hazardous and/or critical applications.
A.3. Operation of telecommunications and transmission systems where exact signal interfaces and circuit confirmations are essential to mission success.
A.4. Research and technology development (see NPR 7120.8), manufacturing, inspection, testing, operations, maintenance, support, or other applications where the accuracy of measurements is essential to achieve mission success.
A.5. NASA publications or other documents released for external review whose conclusions/recommendations depend upon the accuracy of measurement results and that impact the safety or success of NASA missions. Excluded are preliminary research papers and research instruments under development that have not had traceable units of measurement established.
A.6. Physical measurements used to apportion, levy, or otherwise assign cost(s), or ensure local, State, or Federal regulatory compliance.
B.1 The term "customer," when used in a calibration standard, means the NASA Center and/or program organization that receives calibration or testing services.
B.2 End-of-period-reliability (EOPR) values equal to or greater than 89 percent are considered acceptable evidence of compliance to ANSI/NCSL Z540.3 subclause 5.3.b, false acceptance requirements, and subclause 5.3.3, measurement uncertainty requirements, where such values are derived from statistically significant empirical data.
B.3 Original equipment manufacturers (OEM) may provide proprietary calibrations for their MTE. In such cases, the OEM should provide evidence of traceability and documented test data.
B.4 Guidance concerning estimation and evaluation of measurement decision risk, including false accept risk, is provided in NASA-HDBK 8739.19-4, Estimation and Evaluation of Measurement Decision Risk, and in the NCSLI Handbook for the Application of ANSI/NCSL Z540.3-2006, Requirements for the Calibration of Measuring and Test Equipment.
B.5 Guidance and methods for controlling the accuracy of measurement results are provided in the NASA-HDBK 8739.19 series of measurement handbooks. The handbooks are found at http://www.hq.nasa.gov/office/codeq/doctree/hdbk873919.htm.
