This Decision stipulates the Catalogue of Measuring Instruments Subject to Verification and Registration for Verification. It applies to organizations and individuals producing, repairing, importing, and using measuring instruments listed in the designated catalogue. The subjects must register for verification periodically or when there is a specific need.
Scope of application
The General Department of Standardization, Metrology and Quality, local Standardization, Metrology and Quality Control Branches, and organizations and individuals producing, repairing, importing, and using measuring instruments subject to verification.
Key points
- Measuring instruments used for quantifying goods and services in trade and payment; measuring instruments directly related to safety, health, and the environment must be verified periodically (e.g., commercial rulers, analytical balances, cold water meters).
- Newly produced, imported, or repaired measuring instruments can only be verified when installed and operational.
- Manufacturers and importers of measuring instruments must register for initial verification; users of measuring instruments must register for periodic verification; repair facilities for measuring instruments must register for irregular verification.
- Verification organizations are responsible for accepting and fulfilling verification requirements from the entities, and guiding them to other verification organizations if their current capacity is exceeded.
- Verification fees are collected and managed by verification organizations according to current regulations.
🌐 Social impact of this document
- Positive impact: Ensuring the accuracy of measuring instruments, thereby improving product and service quality, and protecting consumer rights.
- Negative impact: Registration verification costs may increase for businesses, particularly small and medium-sized enterprises.
❓ Frequently asked questions
What must manufacturers of measuring instruments do?
They must register for initial verification with authorized verification organizations. The verification cycle depends on the type of measuring instrument (e.g., commercial rulers require only initial verification, analytical balances once a year).
When must users of measuring instruments register for verification?
They must register for periodic verification according to the specified cycle (e.g., table scales once a year, cold water meters every five years).
What must repair facilities for measuring instruments do?
They must register for irregular verification when needed. The verification cycle depends on the type of measuring instrument (e.g., current transformer measuring equipment every five years).
How does a verification organization collect verification fees?
Verification fees are collected and managed by verification organizations according to current regulations, which are not specifically detailed in this document.
If newly produced, imported, or repaired measuring instruments can only be verified when installed and operational, what must the entity do?
The user of the measuring instrument must register for initial or irregular verification with the verification organization authorized for that type of measuring instrument. The verification cycle depends on the type of measuring instrument (e.g., current transformer measuring equipment every five years).

1.2.Standards used for calibrating the measuring instruments listed above must also be calibrated. The calibration cycle follows the calibration procedures for standards issued by the Standard Metrology Quality Control Bureau.
13. Measuring instruments not included in the above list, if used for forensic examination and other state administrative activities, must be calibrated on a case-by-case basis. The Standard Metrology Quality Control Bureau is responsible for organizing the implementation of this work at the request of relevant state agencies.
2. Registration for calibration of measuring instruments.
2.1.General provisions.
2.1.1.Subjects required to register for calibration.
Organizations and individuals (referred to collectively as entities) engaged in manufacturing, repairing, importing, and using measuring instruments listed for mandatory calibration shall register for calibration with authorized calibration organizations as follows:
a)Entities manufacturing or importing measuring instruments must register for initial calibration;
b)Entities using measuring instruments must register for periodic calibration;
c)Entities repairing measuring instruments must register for irregular calibration.
2.1.2.For newly manufactured, imported, or repaired measuring instruments, they can only be calibrated when installed in operational position. The entity using the measuring instrument shall then proceed to register for initial or irregular calibration with the calibration organization authorized to calibrate that type of measuring instrument.2.1.3.Based on their recognized or delegated calibration capabilities, entities may choose the most convenient calibration registration location for their business, production, and usage needs.
2.1.4.Calibration organizations have the responsibility to accept and meet the calibration requirements of entities within their recognized or delegated capabilities. In cases where certain measuring instruments exceed their calibration capabilities, the calibration organization will guide the entity to register with another nearby calibration organization capable of calibrating those instruments.
2.1.5.Calibration organizations are responsible for collecting and managing calibration fees in accordance with current regulations. 2.2.Form of registration. 2.2.1.When there is a need for large-scale calibration, the entity must submit a calibration registration form for measuring instruments to the calibration organization (model form attached as an appendix).
Within ten days from the date of receipt of the registration form, the calibration organization must inform the entity of the specific plan for conducting the calibration and the preparations needed for the requested calibration. 2.2.2.In cases of individual and simple calibration needs, the entity may notify the calibration organization in advance before bringing the measuring instrument for calibration without prior registration. The calibration organization has the responsibility to meet these needs in accordance with its capacity and calibration schedule./.

Note:.
Column "Accuracy grade" should indicate the accuracy grade or characteristic of accuracy (permissible error, value of division, uncertainty of measurement,...).
Column "Calibration regime" should clearly specify initial, periodic, or irregular calibration.
Column "Place of calibration" should clearly indicate the request for calibration at a calibration organization or at the entity's premises (on-site calibration).
The "Level/Accuracy" column records the accurate level or characteristic of accuracy (permissible error, scale value, measurement uncertainty, etc.).
The "Calibration Regime" column specifies the initial, periodic, or irregular calibration regime.
The "Calibration Location" column indicates the request for calibration at a calibration organization or at the premises (on-site calibration).
