Metrological verification is an old and advancing career. As a basis for measuring the performance of measuring instruments, the verification procedures play an increasingly normative role in China's metrology industry, and are the premise of accurate measurement results. Demand for market changes, upgrading of technology, and speeding up of measurement institutions Instrumentation The pace of verification procedures.
In the first half of 2018, instrument meter The industry is welcoming the period of rapid development. The calibration specification is the guarantee of the industry technology. The development of instrumentation is increasingly inseparable from the promotion of calibration specifications. In the past six months, China's instrumentation procedures have been completed and completed for the instrument industry. Flourishing escort.
Sulfur dioxide Gas detector Type evaluation outline"
As China's economy moves towards high-quality development, it has made stricter pursuits on economic benefits and ecological benefits. Therefore, it is necessary to conduct rapid, reliable and accurate detection of toxic gases such as sulfur dioxide. To further improve the accuracy and efficiency of hydrogen sulfide detection. Promote the normative progress of the relevant market. On January 19th, the National Environmental Chemometrics Technical Committee released the JJF 1364-2012 "Sulphur Dioxide Gas Detector Type Evaluation Outline" for comments, and for the national measurement institutions, research institutes, etc. Relevant units solicit opinions.
The draft of the "Ultrasonic Windometer Calibration Specification" was officially released
The wind speed detector can monitor and display the measured wind speed change. With the development of ultrasonic technology, ultrasonic waves play an important role in wind speed measurement, fluid flow rate and flow measurement, benefiting from meteorology, greenhouse, building and other fields. The technology and level of the wind meter promoted the normative development of the relevant market. On May 15, the Meteorological Subcommittee of the National Pressure Measurement Technical Committee issued a draft of the "Specification Specification for Ultrasonic Wind Meters". This specification applies to two-dimensional ultrasonic testing. Calibration of the wind gauge.
Opinion draft of "Automatic Weather Station Wind Speed Sensor Calibration Specification" released
'Knowing ourselves and knowing each other, there is no war.' Environmental monitoring, as a prerequisite for environmental work, provides an indispensable scientific data basis for pollution source control and environmental management control. In recent years, the state has invested heavily in environmental protection construction, and the environmental monitoring market continues to be hot. Elevated, the development shows a good trend of rapid growth. In order to further standardize the sensor market of automatic weather station, on May 15, the Meteorological Subcommittee of the National Pressure Measurement Technical Committee issued the draft of the "Automatic Weather Station Wind Speed Sensor Calibration Specification".
The "Guidelines for Calibration of Scintillator γ Spectrometer" was officially released
Scintillation detectors are detected by the use of ionizing radiation to produce flashes in certain materials. They are also one of the most widely used and widely used ionizing radiation detectors. With the application of micro-light detectors and related technologies, The scintillator detector has been developed very rapidly. It is necessary to carry out the calibration of the scintillator detector spectrometer. On June 12, the National Ionizing Radiation Measurement Technical Committee issued the "Specification Specification for the Scintillation Detector γ Spectrometer". Draft for comments. For the first time, the national metrological calibration specification. Applicable to the calibration of the scintillator detector gamma spectrometer, but not for the calibration of high purity gamma spectrometer.
"Procedures for verification of spectrum analyzers for communication"
Based on the characteristics of fast, high-throughput, non-destructive, etc., spectral analysis technology has become one of the best choices for enterprises to improve product quality and improve production efficiency. Demand guidance market, spectrum analyzer calibration and measurement are also concerned by metrological verification personnel. On June 14, the National Optical Metrology Technical Committee issued the "Provisions for the Calibration of Communication Spectrometers" for comment. It is reported that this procedure is applicable to the first verification, subsequent verification and in-use inspection of communication spectrum analyzers.
"Bimetal thermometer calibration specification" draft for comment
With the development of science and technology, high-precision digital thermometers, thermometers, etc. have the advantages of high accuracy, good stability, etc., overcome the shortcomings of the standard mercury thermometer pollution environment, easy to break, and are more and more widely used. Moreover, its metrological performance indicators can meet the requirements of bimetal thermometer calibration work. On June 15, the National Temperature Measurement Technical Committee issued a draft of the "Bimetal Thermometer Calibration Specification", and it is aimed at measurement institutions, research institutes, etc. across the country. Unit companies solicit opinions.
Opinion draft of "Lens Center Deviation Measuring Instrument Calibration Specification" released
The lens center deviation measuring instrument is an optical measuring instrument (or detecting device) for measuring the eccentricity of the lens by using a lens or a lens group fixed on the high-precision rotary axis table and using the self-aligned principle of parallel light reflection self-alignment in the self-aligned optical path. In order to help the industry's standardized and orderly development, a few days ago, the National Geometric Quantity Engineering Measurement and Measurement Technical Committee issued a draft for the "Cornerization of the lens center deviation measuring instrument", and solicited opinions from the provincial and municipal metrology institutes and related units.
"锗 射线 γ spectrometer calibration specification" comments draft is released
Γ-ray spectrometer is one of the most important measuring instruments in the field of radioactivity measurement. It has been widely used in many scientific and social fields such as nuclear power, environment, inspection and quarantine, biomedicine, etc. July 5, The 校准 γ ray spectrometer calibration specification was published. The instrument manufacturers in the industry can actively contribute ideas and ideas for the industry's normative scientific development.
Under the great tide of China's economic development, measurement and verification have become an important yardstick for measuring social and economic development and scientific level. The instrument industry is increasingly standardized and orderly, and for thousands of testing equipment companies, Always pay attention to the latest verification procedures and standard methods of various instruments, from the technical requirements, performance improvement, process improvement and other aspects of innovation and upgrade, and effectively promote the good development of the instrumentation industry.
