[ Focus on Chemical Machinery Equipment Network ] Recently, the East China National Metrology and Testing Center released the "Laser Marking Instrument Calibration Specification" as the "Shanghai, Jiangsu, Zhejiang and Anhui" measurement technical specifications, numbered JJF (Shanghai, Jiangsu, Zhejiang and Anhui) 4002-2021, since 2022 Implemented in the Yangtze River Delta on March 20
.
This marked the official release of the first "Shanghai, Jiangsu, Zhejiang and Anhui" metrology specifications jointly established by three provinces and one city in the Yangtze River Delta region led by Anhui
.

Chemical machinery and equipment network hotspots pay attention to chemical machinery and equipment

The "Laser Marker Calibration Specification" was projected and announced by the East China National Metrology and Testing Center in September 2020 as the first batch of mutual recognition projects for the construction of metrological specifications in the Yangtze River Delta, and was drafted under the auspices of Wuhu Metrology Institute
.
There are 7 mutual recognition projects in this batch, including 3 joint construction projects and 4 mutual recognition projects.
The "Laser Marking Instrument Calibration Specification" is not only one of the 3 joint construction projects, but also the 2 joint construction projects approved by Anhui One of the mutual recognition projects
.

After the "Laser Marking Instrument Calibration Specification" was approved and approved, the Anhui Provincial Market Supervision Bureau strengthened internal and external communication and coordination, daily research and supervision, and strengthened guidance in accordance with the relevant provisions of the "Shanghai, Jiangsu, Zhejiang and Anhui" Measurement Technical Specifications System Amendment Implementation Rules.
Promote efforts to provide a strong guarantee for the development of regulations
.
Wuhu Municipal Market Supervision Bureau attaches great importance to support, the main leaders often intervene, the leaders in charge take the lead, and the business departments follow-up services
.
Wuhu Metrology Institute actively carried out investigation and research, test verification, drafting texts, soliciting opinions, etc.
, and standardized research and development work was smooth and efficient
.

On the basis of soliciting opinions in the province, organizing expert seminars, and soliciting opinions from the National Professional Metrology Technical Committee within the Yangtze River Delta, on June 29 this year, the Anhui Provincial Market Supervision Bureau, together with the East China National Metrology and Testing Center, united Shanghai and Jiangsu , Zhejiang, one city and two provinces market supervision bureau, organized a "laser marking instrument calibration specification" review meeting in Wuhu, Anhui
.
After the unanimous agreement of the verification experts from the Yangtze River Delta region, the "Laser Marker Calibration Specification" became the first batch of the first approved "Shanghai, Jiangsu, Zhejiang and Anhui" metrology specifications
.

　　"Laser marking instrument calibration specification" uses level, theodolite, multi-tooth indexing table and other measurement standards to establish a space standard calibration field, which solves the traceability of measurement parameters such as horizontal and inclined placement of horizontal line inclination, vertical line inclination, and vertical plane angle.
, The calibration method is simple and the operability is strong
.

　　As the first "Shanghai, Jiangsu, Zhejiang, and Anhui" measurement technical specifications jointly established by the Yangtze River Delta region, which was jointly established by three provinces and one city, the standard demonstrated the measurement technology development level in surveying and mapping in the Yangtze River Delta region and filled the gaps in the measurement technical specifications in this field in the Yangtze River Delta region.
It provides strong technical support for the legal metrological management of laser marking instruments, and is of great significance for driving the construction of the "Shanghai, Jiangsu, Zhejiang and Anhui" metrological standards system, echoing and promoting the integrated high-quality development of the Yangtze River Delta
.

　　Original title: The "Shanghai, Jiangsu, Zhejiang and Anhui" measurement technical specifications jointly built by three provinces and one city in the Yangtze River Delta are officially released
