Brief introduction
Division of Compulsory Verification for Measuring instrument mainly carries out compulsory verification for measuring instruments, metrological inspection for net content of prepackaged commodities with fixed content in the central area of Shanghai Municipality, helps the administrative departments for measurement to record the necessary information about the measuring instruments subject to compulsory verification, and allots conformity tags of compulsory verification, etc. The main laboratories of the division are located at Yishan Road branch and Jiangqiao branch, equipped with measuring facilities at the advanced international level. The Shanghai Glasses Measurement Station is set up in this division, providing third-party data of glasses between the seller and the buyer. There are three experts in this division actively participating in the works of relevant national metrology technical committees and work groups.
The division has established 27 public standards of measurement, among which 6 are the highest level ones in eastern China area. The division carries out pattern evaluations of new and imported measuring instruments, verification of imported measuring instruments, and supervision inspection for the quality of measuring instruments, appointed by the administrative departments for measurement at different levels. The division is capable of carrying out 53 verification items, 34 calibration items and 20 testing items. The mission of this division focuses on providing technical supports to the administrative departments in dealing with measurement affairs related to public daily life.
Another important task of this division is carrying out researching activities for measurement and testing, developing national technical specifications and standards. The division has received several items of Science and Technology Progress Awards conferred by the Shanghai Municipal Government. Some research achievements have been adopted by national verification regulations. Many self-developed measuring facilities have been the first ones in China.
Service features
The verification of taxi meter applies RFID technology, one taxi meter affixed with one RFID chip to write in the necessary information about this particular meter and car, which is first used in China. This method effectively ensures that one taxi bears its own particular and verified meter, supports the whole process automatic examination and verification of taxi meter, shortens the waiting time of taxi driver, and provides administrative inspection of taxi meter a way to check if the meter is verified by reading the relevant information stored in the RFID chip using a special handset.
The in-vehicle inspection apparatus for fuel dispensers is self-developed which can carry out the examination of the quantity accuracy of the fuel filled into a special tank of the inspection apparatus, while the vehicle acts as a normal one at the filling station. This helps the administrative departments supervising the behavior of various gas stations.
The verification apparatus for liquefied petroleum gas dispensers is self-developed with the function of multi-parameters collection, which can carry out on-the-spot verification, technically leading in China.
The testing equipment for net content of prepackaged commodity with fixed content has the function of automatically timing thawing and dripping, weighing, package cleaning, collecting and distinguishing measurement data, and batch processing the measurement results, reaching the top level in this field domestically.
The laboratory of multi-function mobile testing is the unique one in China which can carry out tests of multi-parameters. It contains a quakeproof worktable which is dismountable and hydraulic controlled for rise and fall, and with self-equipped power supply enabling it to continuously work for more than eight hours without connecting to external power source.
The laboratory for calibrating vehicle standard headlamps is equipped with a 10-meter dark room. It can calibrate the near- and far-light standard headlamps with the characteristics of computer displaying light pixels and high resolution. It’s the first one in China.
The lens film testing system can conduct non-destructive test for eyeglasses and film materials, which is the first one in domestic glasses testing field. It can automatically measure the thickness of multi-layers optical film, and the refractive index of the film and the original lens. It can also evaluate and analyze the quality of filmed eyeglasses.
