The user must determine the purpose of the measuring device. Through the purpose of use, the measuring devices will be divided into 2 categories: Group 1 measuring media and group 2 measuring media. In it:
a. Group 1 measuring media
Are the means of measurement used in scientific research, control, technological process adjustment, quality control in production. Or other purposes not within the scope of the controlled group 2 means of measurement according to the measurement technical requirements published by organizations and individuals.
For the means of measuring group 1 “inspection” or “calibratation” in the voluntary form of organizations and individuals. Organizations and individuals can choose to “audit” or “calibrate” or both according to their requirements and wishes.
Group 1 measuring vehicles are “tested”, “calibrated” at units providing inspection, calibratation, testing of measuring instruments, measurement standards in accordance with supply 105/206/ND-CP and Decree No. 154/2018/ND-CP.
b. Group 2 measuring media
These are means of measurement used to quantify goods and services in purchase, sale and payment. The aim is to ensure safety, protect public health, protect the environment in inspection, inspection, judicial expertise and other public service activities must be controlled according to the measurement technical requirements prescribed by competent state management agencies for measurement.
For the means of measuring group 2 “inspections” of a mandatory nature, they must comply with the requirements as prescribed by law. Group 2 measuring instruments must be tested in the following cases:
– Initial inspection when put into use
– Periodic inspection during use
– Inspection after repair
The list of group 2 measurement instruments issued by the Ministry of Science and Technology in accordance with Circular No. 23/2013/TT-BKHCN and Circular No. 07/2019/TT-BKHCN amending a number of articles of Circular 23/2013 clearly specifies the names, measurement control measures and inspection cycles.
See measurement regulations for group 2 media here:
Group 2 means of measurement must be inspected at the inspection, calibratation, testing of measuring instruments, measurement standards “designated” in accordance with Decree 105/2016/ND-CP and Decree 154/2018/ND-CP.
As mentioned above, the “inspection” or “calibratation” of group 1 measurement means is a voluntary form that is not mandatory. However, in some areas such as pharmaceuticals, health foods or cosmetics, the good practice guidance system requires the implementation of “periodic calibration” of these measuring devices and that is also the content of concern of inspectors when conducting inspections of facilities producing such products. For group 2 measurements, it is always mandatory in accordance with the law in all sectors and sectors.
