1. Where included in the scope of A-level management of measuring instruments should be measured according to the requirements of the national verification procedures to the government measurement of the administrative department to apply for verification. Measured by the government administrative department authorized to carry out self-test of the enterprise, should also be strictly in accordance with the requirements of the national verification procedures to arrange for verification.
2. There is no verification of measuring instruments, enterprises should be in accordance with the relevant provisions of the State to develop their own calibration or comparison methods, and reported to the local administrative department for the record.
3 Where the use of mandatory calibration of measuring instruments units, should be set up full-time or part-time management to ensure that the implementation of the cycle in strict accordance with the regulations and supervise and check the use of the situation.
4. The use of standardized material units, should be strictly kept and operated. Article VIII B measurement instruments management
1. For continuous operation of the device is not disassembled to make the measuring instruments, according to the relevant verification procedures, can be synchronized with the maintenance cycle of the equipment verification cycle, but in the daily operation, it must be strictly supervised and inspected.
2. Higher accuracy requirements, but stable performance, infrequent use of measuring instruments verification cycle can be appropriately extended. The extended time should be to ensure the reliability of measuring instruments as a principle. High frequency of use and the need to ensure the use of precision measuring instruments, should be appropriate to shorten the verification cycle.
3. General measuring instruments dedicated, according to its actual use, according to the requirements of the verification procedures, may be appropriate to reduce the verification of the project or only part of the project verification, but the verification certificate should indicate the permitted scope of use and use of the location, and in the obvious position of the measuring instruments labeled post limitations sign.
4. There is no verification of measuring instruments, should refer to Article VII, paragraph 2. Article IX C measurement instruments management
1. For some accuracy is not strictly required, the performance is not easy to change the low-value consumable or as a tool for the use of measuring instruments, the implementation of a one-time verification.
2. Non-production of key parts of the role of instructions, low frequency of use, stable and durable performance and continuous operation of the fixed installation of measuring instruments on the equipment, you can implement the management of the validity period, or to extend the verification cycle, generally controlled in 2 to 4 cycles.
3. There is no verification of measuring instruments, should refer to Article 7, paragraph 2.
4. Measuring instruments for life and welfare is strictly prohibited into production and other areas of use.
5. Included in the C-level management of the rest of the measuring instruments, according to the category of measuring instruments and the use of supervision and management. Chapter IV By-laws Article X enterprises must purchase a license to manufacture measuring instruments and certification of measuring instruments.
