Including measuring equipment and measuring devices, while measuring equipment includes measuring instruments
Measuring instruments is defined as: can be used alone or with auxiliary equipment to determine the value of the object to be measured, either directly or indirectly, gauges or devices. Measuring instruments can be divided into the following three categories:
(1) gauge. That is, with a fixed form of reproducing the value of measuring instruments, such as the amount of block, broken code, standard battery, standard resistance, bamboo ruler. Line ruler, etc.;
(2) measuring instruments. To be measured quantity is converted into directly observable indicator value equivalent information measuring instruments, such as pressure gauges, flow meters, thermometers, ammeters. Electrocardiograph, etc.;
(3) measurement device. That is, in order to determine the measured value must be the overall combination of measuring instruments and auxiliary equipment, such as mileage meter calibration device, high-frequency microwave power meter calibration device.
And monitoring devices and measuring devices and different, monitoring device is used to monitor the production or service process of the working state of the device, is an integral part of the production equipment;
Measuring devices are generally used to quantify the value of the determination of the results can be based on the measurement results to determine whether the object to be measured in accordance with the specified requirements, including raw materials, finished product inspection used in the specifications, quantity, Weight, chemical composition, packaging and other analytical instruments.
Distinguishing between monitoring devices and measuring devices is not the focus of the device itself, but the role of the device in the entire process and function, monitoring device is the process of process parameters of the monitoring, measuring devices are used to determine the value of the product directly. Such as the same is the national compulsory verification of measuring instruments pressure gauge, when it is used to obtain the pressure value of the object being measured is the measurement device, and was installed in the steam boiler, used to monitor the production of steam used in the physical properties of the device has become a monitoring device.
(I) classification principles 1. Class A measuring instruments
Class A measuring instruments refers to the implementation of the fixed-point fixed-cycle calibration of the mandatory verification of measuring instruments and in the production and operation of the key occasions (quality control points) using measuring instruments. For example: (1) the highest standard of measurement and other measuring instruments; (2) the first level of energy measurement;
(3) in and out of the plant material accounting and bulk products out of the factory;
(4) trade settlement, safety and security, environmental monitoring, medical and health care, and is included in the directory of mandatory inspection of the work of measuring instruments within the measuring instruments;
(5) the key raw materials, Components, outsourcing outsourcing parts of the key quality acceptance; (6) the key parameters of the product quality inspection; (7) process control of key parameters; (8) the enterprise's internal precious materials, goods testing. 2.B class measuring instruments
B class measuring instruments refers to the production and operation of enterprises in general in the internal use of measuring instruments, such as: (1) the development of new technologies, new product development; (2) two or three levels of energy metering; (3) the internal management of materials with the enterprise;
(4) trade settlements, safety and security, environmental monitoring, medical and health care, and is not included in the mandatory inspection of measuring instruments within the directory of measuring instruments. Measuring instruments in the catalog;
(5) general raw materials, components, outsourcing outsourcing quality acceptance;
(6) product quality of the general parameters of the test; (7) process control of non-critical parameters. 3.C measuring instruments
C measuring instruments, including the need for periodic calibration, or can be postponed, or non-critical occasions, as a general indication of measuring instruments, such as:
(1) the State Council measurement of the administrative department of the measurements ordered to allow a one-time calibration of measuring instruments; (2) the implementation of the validity of the management, do not have to carry out the cycle of calibration of the standard substance;
(3) the measurement of the quality of the product with general parameters of the test; (7) non-critical parameters of the process control. p>(3) in the production process, not easy to dismantle, only as a general indication of measuring instruments;
(4) corporate living quarters, as internal energy distribution, employee welfare, or auxiliary production of measuring instruments;
(5) other low-value and easy to consume, non-compulsory measuring instruments.
(B) classification management requirements
The ABC classification of measuring instruments according to different management methods, not back to the management requirements. 1.A class of measuring instruments management requirements
A class of measuring instruments, is mandatory calibration, should be mandatory calibration of the relevant measurement laws and regulations for the fixed-point calibration cycle, in which the highest enterprise measurement standards should also be handled for the measurement of standard assessment certificate. Belong to the non-compulsory testing of measuring instruments, by the enterprise to develop specific verification management methods and rules and regulations, the provisions of the unit's management of the detailed catalog of measuring instruments and the corresponding verification cycle, to ensure that the use of non-compulsory testing of measuring instruments for regular verification. Measurement verification should be carried out measurement verification procedures; enterprises should be set up for Class A measuring instruments full-time (or part-time) measurement of personnel; enterprises should strengthen the Class A measuring instruments issued by the measurement of data supervision and certification. 2.B type of measuring instruments management requirements
Enterprises should develop specific verification management methods and regulations, the unit management of measuring instruments detailed catalog and the corresponding verification cycle. There is no measurement and verification procedures, or the enterprise's own special measuring instruments, should be developed by the enterprise calibration method for calibration. 3.C category of measuring instruments management requirements
C category of measuring instruments, measuring instruments belonging to the State Council measurement of the administrative department ordered the first verification of measuring instruments, enterprises should purchase a one-time inspection of measuring instruments, and to develop the use, operation, maintenance, storage and scrapping of the management system to ensure that the use of the integrity. Is a standard substance, to purchase a manufacturing license, to be used within the validity period, and be strictly preserved. Not easy to dismantle, the need to extend the verification of measuring instruments, to be clear with the overhaul period synchronized with the verification cycle. For non-critical occasions, or low-value consumable measuring instruments, can be a one-time verification, failure and scrap. The overall combination of tools and auxiliary equipment, such as mileage meter calibration device, high-frequency microwave power meter calibration device.
And monitoring devices and measuring devices are different, monitoring devices are used to monitor the production or service process of the working state of the device, is an integral part of the production equipment;
Measuring devices are generally used to quantify the value of the determination of the results can be based on the measurement results to determine whether the object to be measured in accordance with the specified requirements, including raw materials, finished product inspection of the specifications used in the number, Weight, chemical composition, packaging and other analytical instruments.
Distinguishing between monitoring devices and measuring devices is not the focus of the device itself, but the role of the device in the entire process and function, monitoring device is the process of process parameters of the monitoring, measuring devices are used to determine the value of the product directly. Such as the same is the national compulsory verification of measuring instruments, pressure gauges, when it is used to obtain the pressure value of the object to be measured is the measurement device, and was installed in the steam boiler, used to monitor the production of steam used in the physical properties of the device has become a monitoring device.
