The technical specifications of the optical metering field revised this time will more accurately ensure the unity and accuracy of the quantity value of optical communications, spectral radiation, and spectral characteristics in related fields. In particular, the "Average Color Temperature Standard Lantern Standard Specification" provides support for the inspection and testing of the color parameters of electro -optical source products and the evaluation of lighting comfort, which helps the evaluation, promotion and application of healthy lighting products.

In the field of ionizing radiation metering, the JJF1979-2022 "Calculation Specification Specifications for Radiovision inert gas monitoring instrument". The release and implementation of this specification provides a unified, standardized and scientific technical basis for the measurement characteristics of the radioactive inert gas monitor. In order to ensure the accurate and reliability of the surveillance of radioactive inert gas activity monitoring, improve the supervision of the emission volume of the nuclear facilities gaseous outflow, and promote the domesticization of radioactive inert gases monitoring in technology.

In the field of environmental chemical measurement, the JJF1977-2022 "Calculation Specifications for Water Volatal Phenol Online Monitoring". The standard release and implementation provides detailed calibration methods and quantitative traceability basis for the instrument manufacturers and users, which is of great significance to ensure the quality of instrument, further improve the quality system of water quality, and improve the construction of environmental early warning monitoring capabilities.

In the field of electromagnetic metering, the JJG1148-2022 "Electric Vehicle AC Charging Pile Verification Regulations" (trial) and JJG1149-2022 "Electric vehicle non -vehicle charging machine verification procedures" (trial), this revision improved the applicability and applicability and of the procedures On -site verification efficiency, clarify the measurement requirements of electric vehicle charging piles (charger), and promote the rapid and healthy development of the electric vehicle industry.

In the field of time frequency measuring, the JJF1980-2022 "Road Traffic Technology Monitoring System Time Parameter Calculation Specification" is formulated. The specification provides the technical basis for the calibration of time parameters in the road traffic technology monitoring system. The implementation of the next step will effectively solve the problem of time and source of the time limit for road traffic technology monitoring systems to ensure the accuracy and reliability of its system time. , Help smart traffic standardization and standardization.

In the field of biological measurement, formulation and release of JJF1972-2022 "Credit Specifications for the Performance Parameter Performance Parameter Parameter of the Protective Ambulance", JJF1973—2022 "Code for the Performance Performance Performance Performance Parameter of Mobile Biological Testing Experiment" and JJF1974-2022 " Measurement methods". The specification provides method guidance for the daily calibration of negative voltage ambulance medical cabins and mobile biological testing experimental cabins, and also provides technical support for quality control and daily maintenance. The standardized release and implementation will effectively support the prevention and control of public biological safety epidemic such as new crown pneumonia, and ensure that the quality of chemical biodegradation data meets the requirements of global chemical management.

In the field of medical measurement, the JJG 892-2022 "Optical Examination Regulations" (instead of JJG 892-2011).This revision will provide more complete technical means and regulations for the compulsory verification of the optical test to ensure that the functional parameters of the optical test instrument are accurate, and effectively support the eight departments of the Ministry of Education, the Health and Health Commission, and the General Administration of Market Supervision.The implementation of the Implementation Plan for the Prevention and Control of Children and Adolescents, and effectively gives full play to the basic guarantee role of measurement in preventing and controlling myopia and protecting children's and adolescent vision health.In the field of new materials and nano -measurement, the JJF1981-2022 "Nano -Pressing Equipment Standards" is formulated.The release and implementation of this specification uses nano -entersing instruments in R & D and industrial applications for micro -nano -film materials and devices.Promote the use of micro -nano -film materials and devices to provide metering support in the application of related industries.
