11、 or networking permitted without license from IHS-,-,-MIL-STD-1839D 1 1. SCOPE 1.1 Purpose. This standard describes the requirement to provide a means for calibration and measurement traceability of all system, subsystem, and equipment. From this point on in this document, the word system will refer
12、 to system, subsystem, and equipment. This ensures system operational integrity and accuracy. It defines the requirement for establishing measurement traceability from actual system level measurements to the National Institute of Standards and Technology (NIST) or other approved measurement sources.
13、 1.2 Applicability. The requirements of this standard apply to all systems that require measurements of any type to ensure proper operation. 1.2.1 Application guidance. When Logistics Support Analysis (LSA) is required on an acquisition program, the requirements of this standard should be an integra
14、l part of the LSA effort. Data developed as a result of this standard should be documented in and become part of the LSA documentation. When LSA is exempted or the LSA is tailored to exempt development of the data requirements, this standard can become an independent compliance document of the acqui
15、sition program and tailored in accordance with the contract. 2. APPLICABLE DOCUMENTS 2.1 General. The documents listed in this section are specified in sections 3, 4, and 5 of this standard. This section does not include documents cited in other sections of this standard or recommended for additiona
16、l information or as examples. While every effort has been made to ensure the completeness of this list, document users are cautioned that they must meet all specified requirements documents cited in sections 3, 4, and 5 of this standard, whether or not they are listed. 2.2 Government documents. 2.2.

23、ndard and the references cited herein, the text of this standard will take precedence. Nothing in this standard, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3. DEFINITIONS 3.1 Definitions 3.1.1 Accuracy. Closeness of agreement between a measured
24、 quantity value and a true quantity value of the measured. 3.1.2 Built-in-Test (BIT). A test approach using built-in test equipment or self-test hardware and software that is internally designed into the supported system, subsystem, or equipment to test all or a part of that system, subsystem, or eq
25、uipment. 3.1.3 Built-in-Test Equipment (BITE). Any device which is a part of a system, subsystem, or equipment and is used for the express purpose of testing the system, subsystem or equipment. BITE is an identifiable unit of the system, subsystem, or equipment. 3.1.4 Calibration. The set of operati
26、ons that establish, under specified conditions, the relationship between values of quantities indicated by a measuring instrument or measuring system, or values represented by a material measure or a reference material, and the corresponding values realized by standards. 3.1.5 Calibration Interval.
27、The maximum time an item of TMDE, may go between calibrations and still achieve its target measurement reliability. 3.1.6 Calibration and Measurement Requirements Summary (CMRS). A report which details the measurement requirements of a system, subsystem, or equipment; the TMDE, and the calibration s
28、tandards and equipment required to assure traceability of all measurements through the applicable individual military services metrology and calibration program. 3.1.7 Design Activity. A design activity is an activity that has responsibility for the design or Provided by IHSNot for ResaleNo reproduc
29、tion or networking permitted without license from IHS-,-,-MIL-STD-1839D 3 modification of an item. The activity may be a U.S. Government, commercial, or nonprofit organization. 3.1.8 Interface Test Adapter. The point located on the ATE where all input and output signals are accessible for connection
30、 to an external UUT or calibration standard. 3.1.9 Logistics Support Analysis (LSA). The selective application of scientific and engineering efforts undertaken during the acquisition process, as part of the system engineering and design process, to assist in complying with supportability and other I
31、ntegrated Logistics Support (ILS) objectives. The LSA process is a planned series of tasks performed to examine all elements of a proposed system to determine the logistics support required to keep that system useable for its intended purpose; and to influence the design so both the system and suppo
32、rt can be provided at an affordable cost. 3.1.10 Measurement Traceability. The property of the result of a measurement or the value of a standard whereby it can be related to stated references, usually national or international standards, through an unbroken chain of comparisons all having stated un
33、certainties. Traceability, as used in this standard, applies to measurements/calibrations made from the prime system or subsystem through an unbroken chain of comparisons to the national reference standards. 3.1.11 Support Equipment (SE). All equipment used in calibration and maintenance support of
34、mission and operational equipment. 3.1.12 Support Equipment Recommendation Data (SERD). The document, usually prepared by an equipment manufacturer, which describes the support requirement for an item of equipment and recommends an item of support equipment to satisfy the requirement. 3.1.13 Test Ac
35、curacy Ratio (TAR). A simple comparison between the accuracy of the Unit Under Test (UUT) and the accuracy of the calibration standard. However, this ratio does not consider other potential sources of error in the calibration process. For example, if it is required that an equipment output parameter
36、s accuracy is +/-8% and the accuracy of the single measuring device used to measure the output parameter is +/-2%, then the TAR is 8 to 2 or 4 to 1. 3.1.14 Test, Measurement, and Diagnostic Equipment (TMDE). Any system or device used to test, measure, evaluate, inspect, or otherwise examine material
37、s, supplies, equipment, or a system to identify and/or isolate any actual or potential malfunction, or to determine compliance with specifications established in technical documents (e.g. research, development, test, and evaluation documents; specifications; engineering drawings; technical orders).
38、TMDE is SE that provides for measurement traceability. 3.1.15 Test Program Set (TPS). The ensemble of input-desired response data used to verify the performance of the system under test. 3.1.16 Test Uncertainty Ratio (TUR). The comparison between the accuracy of the Unit Under Test and the estimated
39、 calibration uncertainty is known as a Test Uncertainty Ratio (TUR). This ratio is more reliable because it accounts for possible sources of error in the calibration process that the TAR does not. This value also takes into account issues such as temperature, humidity, Type A (statistical analysis i
40、ncluding actual and random measurement results), and Type B (anything not a Type A) uncertainties. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-STD-1839D 4 3.1.17 Uncertainty. The word “uncertainty” means doubt, and thus in its broadest sense
41、“uncertainty of measurement” means doubt about the validity of the result of a measurement. Because of the lack of different words for this general concept of uncertainty and the specific quantities that provide quantitative measures of the concept, for example, the standard deviation, it is necessa
42、ry to use the word “uncertainty” in these two different senses. 4. GENERAL REQUIREMENTS 4.1 General Measurement Requirements.

43、surement to ensure proper and accurate operation of the system are identified and documented. b. Calibration and measurement actions are conducted as required to maintain accurate operation.
