Its purpose is to ensure that the measurement point is measured accurately and the measurement state is not excessive, and the measurement value can be accurately transferred to the measurement instrument. The components of the calibration system include: The relationship between the measurement instruments and the value transfer from the calibration instrument selected by the certifier to the calibration instrument: the methods and measuring instruments allowed (or recommended) to be used; the uncertainty requirements of the standard instrument to reproduce or preserve the value ; …The metrology-related standards and measurement bases shall be approved by the State Council Metrology Safety Administration and the market shall organize the comprehensive creation and promotion of the system table, and the system table shall meet the requirements of accuracy and capability. In the calibration work, the system table can be used as a reference to determine the appropriate system table. The system table shall be compiled in accordance with the provisions of laws and regulations, and the relationship between the domain and the transmission of information shall be clear. The domestic and foreign cards shall be signed and used, and the verification shall be carried out with sincerity to ensure that the system is suitable for the people and practical. 4 Definitions of Terms National Measurement Standard National Basic Standard JJF1104-26H03 A measurement standard recognized by a country and used as the basis for determining the values of other related quantities in the country. 1.2 [Product Standard] Measurrment Standard is defined as a unit of measurement used to determine, preserve or reproduce a basic value and used as a physical measuring instrument, dating instrument, reference material or measuring system: 1. A group of similar physical measuring instruments or measuring instruments, selected from the group using the same reagents as the collective standard. 2-- They can be used individually or in combination to form a series of different types of standards. 3 This specification refers to the metrological basic technology and metrological standards. 4.3 Measuring instruments measuringinstrurlent measuring instruments Instruments used alone or in combination for measuring points: 4.4 Maximum measurement capability calibrationmcusurcnurnl The apability is expressed by the expanded uncertainty with coverage factor = 2 (acceptance minus P = 95%) based on the most commercially available measurement level provided to users. 5 Structure of verification system table Verification system table consists of the following parts and is arranged in the following order: ·Basic principle Metrology standard Working metrology instrument Block diagram of verification system table |Back cover h Writing requirements 6.1 Cover and back cover The cover and back cover formats of the verification system table shall comply with the provisions of the cover and back cover formats of the main verification system table in the appendix The Chinese name and the English name of the verification system table shall be brief, clear, and accurately reflect its applicable scope. For example: Verification system table for quality instruments, Yerilic.atinn Schema of Measuring Instruments for Mains; (13.81-237.15) Verification system table for temperature measuring instruments, Verification temperature measuring instruments in 1°C from 113.81K to 273.15K. 2 6.2 The format of the front page and back page of the verification system table shall comply with the provisions of Appendix 1 on the format of the front page and back page of the verification system table. 6.3 The scope of application of the verification system table shall be specified in the following paragraphs. 6.4 Measurement standards 6.4.1 Describe the composition and capability of the national measurement value transfer system. The content should include: 1) Name, value or measurement range of the measurement standard; 2) The uncertainty of the measurement value of the measurement standard (-2 or =95); 3) The measuring instrument and measurement method required for transferring the measurement value; 4) The best measurement capability for transferring the measurement value; If the measurement value is not the absolute value of the basic unit, the path and method of value transfer from the basic unit should be explained and indicated with a dotted line in the calibration system table box. 6.4.2 When it is necessary to set up a secondary standard and/or a working standard, all or part of the following contents should also be included: 1) Name, value or measurement range of the secondary standard and working standard; 2) Name of the measurement standard; 3) The uncertainty of the measurement standard (=2 at most); 4) The uncertainty of the measurement standard (=2 at most); When transmitting the value, the measuring instrument and measurement method are required: e) The best measurement capability when transmitting the value: The method of comparison with the metrological standard in the metrological standardization or the value transmission path and method of the reference standard: 6.5 Measurement standardization Explain the composition of the national measurement value transmission system, the classification by grades/levels (if necessary) and the capabilities of various or grades/levels of measurement standards: Contents include: ) The name and measurement range of the measurement standard; h) The name of the measurement standard ) The uncertainty of the measurement standard (=2 or =95%; d) The measuring instrument and measurement method used when transmitting the reference value: ) The best measurement capability of transmitting the value H. 6.6 Working measuring instruments Description of the composition, grades/levels (if necessary) and types or grades of measuring instruments at the lower end of the value transmission system: Capabilities of measuring instruments, including: 6.6, 1 Names and measuring ranges of various typical working measuring instruments: 6.6.2 Accuracy grades/levels or metrological requirements of corresponding working measuring instruments (such as product tolerance, sensitivity, repeatability, etc.), or expressions. 6.6.3 Additional notes: The working measuring instruments in the verification system table should be accompanied by the following notes: 1. There may be new products or different names for working measuring instruments, which cannot be fully marked out in the verification system table: 3 JJF 1104—2IL3 When the calibration system is used, it is necessary to determine the working principle of the calibration system according to the measured value, measurement range and working principle. The system calibration system is composed of the measuring system and working principle, and the appropriate value is determined. The accuracy of the calibration system is reduced from the standard to the standard. The accuracy ratio of two adjacent equal-valued instruments is different in the range of 2. Therefore, the accuracy of the calibration system is relatively large. The difference between the maximum allowable error and the measured value will be different. In actual use, the uncertainty ratio between two adjacent levels should be selected according to the above situation. It can be determined according to the specification and possibility. The larger value can be selected as much as possible. 6.8 The uncertainty of the measurement result cannot be compared with the maximum allowable error of the standard. The uncertainty of the measurement result cannot be compared with the maximum allowable error of the standard. The uncertainty of the measurement result cannot be compared with the maximum allowable error of the standard. tt||, note that the displayed value is not certain, the joint creation of the year 2 of the request for the actual forget degree 5, since. 9 verification system difference world 6,91 verification system table installation cabinet diagram white three and consists of three parts: meter mother sores, measurement standards and working meter years: use dots to separate them: 6.9.2 various standards or measuring instruments such as the name, value or measurement range, the degree of determination of the value or measurement effect, fill in 6.9.3 various meter mother length standard, meter mother standard or working metering instrument, in the process The single value transmission or verification work is related to the geodetic instrument, dating method and the maximum measurement capability used. 6.9.4 The relationship between the transmission of standards is shown in the solid line between the grids. 9.5 The format of the sample diagram of the verification system table is shown in the appendix Verification System Table Cabinet Diagram.
