What are the other technical information that can prove that the measurement standard has the corres

Beijing CIIC Boyuan Management Consulting **** provides you with professional answers: the measurement certification of testing institutions can be roughly divided into the following main steps: (1) Submit the application materials for measurement certification to the provincial (ministry) metrology certification office (including:

quality manuals, program documents, etc.); (2) The provincial (ministry) metrology and certification office shall conduct a written review of the application materials; (3) Through the written review, according to the evaluation criteria of metrology certification, the provincial (ministry) metrology certification office arranges to entrust the technical review team to conduct on-site verification review; (4) Through the on-site review, the testing institutions that meet the requirements of the standards shall be issued by the Provincial Bureau of Quality and Technical Supervision (or ministries) with the measurement certification certificate and the seal of the measurement certification body, and published on the Internet. The declaration of metrological certification** can also be directly on the website**, related to metrological certification....

You can apply to the Chinese Institute of Metrology for measurement audit, and the measurement audit report issued there can be used as supporting information.

In addition, the laboratory usually participates in the reports and results of various inter-laboratory comparison experiments, which can also be used.

Definition of measurement: Measurement is the activity of achieving the unity of units and the accuracy and reliability of the value. Metrology is, by definition, a special kind of measurement, a science – metrology.

Metrology is the science of measurement, including activities such as verification, calibration, value determination, calibration, comparison and testing (of measuring instruments).

Definition of calibration: calibration is a set of operation chains under specified conditions, the first step is to determine the relationship between the quantity provided by the measurement standard and the corresponding indication value, and the second step is to use this information to determine the relationship between the measurement result obtained from the indication value, where the measurement standard provides the quantity value and the corresponding indication value have measurement uncertainty.

Metrology plays a fundamental role in the production of industrial enterprises.

1) Measurement is an important means for industrial enterprises to improve economic efficiency. Improve the means of measurement and testing, strengthen the measurement management, make the reasonable and effective allocation of resources, avoid waste of resources, reduce the consumption of raw materials and energy, and improve the economic benefits of enterprises. If the measurement and testing methods and production management are not matched, the measuring instruments are not complete, and the quantity value is not accurate, it may lead to the loss of control of the manufacturing process, resulting in poor product quality, high consumption and low efficiency.

2) Measurement work is the guarantee to improve product quality. Product quality is the key to the survival and development of an enterprise, and measurement is the most basic guarantee of product quality. In the production process of industrial enterprises, the quality characteristics are characterized by certain measurement characteristics, everything must be used to speak, and the accuracy and reliability of the data must rely on perfect measurement and testing.

If the measuring instruments used by the enterprise are unqualified, the geometric size of the tumbling product may be unqualified, the pressure gauge may not be accurate, the equipment may be destroyed, and the inaccuracy of the analytical balance will cause the product ingredients to be inaccurate ......Therefore, in order to make the product quality of the enterprise reach the advanced level and be invincible, it is necessary to strengthen the measurement and testing methods.

Answer] The relevance validity of the :d calibration scale mainly reflects the correlation between the research tool and other measurement standards, but does not reflect the degree of consistency between the research tool and the concept it is measuring. [This question is aimed at the knowledge points of "basic methods of community nursing research".

The relationship between the research tool and other measurement standards can be reflected in ()aSurface validity.

b.Content feasting to find validity.

c.Structural efficiency and filial piety.

d.The criterion is associated with the degree of validity.

Correct answer: d

A general measuring device is represented or defined by a number of metrological characteristics in order to specifically say what kind of measuring device it is.

For example: Take a pressure gauge as an example:

1.Measuring range: 0-6MPa, 2Accuracy Grade, 3Measuring medium: Non-corrosive liquid, so that you can get a general idea of the information of this instrument.

Of course, there are other measuring ranges and accuracy classes as well as pressure gauges for measuring different media, and a measuring instrument can only be accurately defined if its measurement characteristics are clearly stated.

The main metrological characteristics of general measurement equipment are: measurement range, accuracy level (uncertainty maximum allowable error), power supply voltage, measurement medium, or other technical indicators that can indicate that the instrument is different from other equipment. The above content is for reference.

a.Resolution.

b.The maximum attack is missing, and the mask is allowed to be bored.

c.Measuring range.

d.Weight. Correct answer: ABC
