Recently, the National Metrology Technical Specification JJF2002-2022 “Calibration Specification for Laser Marking Instrument” drafted by Zhejiang Institute of Metrology was approved and released by the State Administration of Market Supervision and officially implemented on June 7.
As one of the important measuring instruments in engineering laser positioning, laser marking instrument is mainly used for the spatial positioning of installation position and the calibration of spatial relationship of engineering facilities in the process of engineering construction. It replaces the horizontal pipe, plumb ball and chalk line in traditional construction decoration, and is widely used in engineering fields such as building construction, decoration and installation of large machinery.
As the world’s largest manufacturing base of engineering laser positioning instruments, China’s publication and implementation of “Calibration Specification for Laser Marking Instruments” provide a comprehensive, scientific and reasonable legal basis and technical guidance for the accuracy and reliability of laser marking instruments, and provide metrological technical support for the high-quality development of laser marking instruments manufacturers. At the same time, it promotes the unification of technical standards in related industries, and also provides technical guarantee for China to strive for the leading position in international ISO standards.
