3. Terms
For the purposes of this standard, the terms and definitions given in GB/T 13966 and the following apply.
3.1
Quality property
A description of the technical status of the instrument, which generally is composed of function, technical parameter and performance characteristic.
3.2
Technical parameter
A description of the main characteristics of the instrument, such as the measurement object, measurement range, minimum detectable quantity, input quantity, output quantity, etc. of the instrument.
Where quantitative assessment is required for a technical parameter of the instrument, the parameter is the performance characteristic.
3.3
Performance characteristic
A quantitative description of the service performance of the instrument and the quantitative assessment criteria during the instrument inspection and acceptance, e.g. the sensitivity, accuracy, repeatability and stability of the instrument. In the technical standards of the instrument, each performance characteristic shall have its corresponding test method.
3.4
Function
A description of the pathway and mode in which the instrument achieves the required performance characteristic, e.g. the operating software, calibration mode, data processing method, alarm mode and signal transmission form of the instrument.
Where quantitative assessment is required for a function of the instrument, such function is the performance characteristic.
3.5
Product standard
A document used for fixing the product technical state. It is the basis for the manufacture, inspection, and assessment of the product. The object of product standard may be a product or a class of product.
4. Instrument Classification and Model Designation
See JB/T 6241.
5. Requirements
