设备校准管理

在JJF1001-1998《通用计量术语及定义》中校准(calibration)的定义是：

在规定条件下，为确定测量仪器或测量系统所指示的量值，或实物量具或参考物质所代表的量值，与对应的由标准所复现的量值之间关系的一组操作。
测量仪器、测量系统、实物量具或参考物质，有时统称为计量器具，本文统称为测量设备。这样，校准可以归结为将测量设备与测量标准进行技术比较，确定被校测量设备的量值及其不确定度的一组操作。
设备校准的目的是确定测量设备示值误差的大小，并通过测量标准将测量设备的量值与整个量值溯源体系相联系，使测量设备的量值具有溯源性。
设备校准应满足的基本要求
1)环境条件校准如在检定(校准)室进行，则环境条件应满足实验室要求的温度、湿度等规定。校准如在现场进行，则环境条件以能满足仪表现场使用的条件为准。
2)仪器作为校准用的标准仪器其误差限应是被校表误差限的1/3~1/10。
3)人员校准虽不同于检定，但进行校准的人员也应经有效的考核，并取得相应的资格证书，只有持证人员方可出具校准证书和校准报告，也只有这种证书和报告才是被承认的。

In JJF1001-1998 General Metrological Terms and Definitions, calibration is defined as a group of operations to determine the relationship between the quantity values indicated by measuring instruments or measuring systems, or the quantity values represented by physical measuring tools or reference materials, and the corresponding quantity values reproduced by standards under specified conditions.


Measuring instruments, measuring systems, physical measuring tools or reference materials, sometimes collectively referred to as measuring instruments, are collectively referred to as measuring equipment in this paper. In this way, calibration can be summed up as a group of operations to compare the measuring equipment with the measurement standard and determine the value and uncertainty of the calibrated measuring equipment.


The purpose of equipment calibration is to determine the magnitude of the indication error of the measuring equipment, and to connect the measurement value of the measuring equipment with the whole measurement traceability system through the measurement standard, so that the measurement value of the measuring equipment is traceable.


Basic requirements for equipment calibration


1) If the environmental conditions are calibrated in the verification (calibration) room, the environmental conditions shall meet the temperature, humidity and other requirements of the laboratory. If the calibration is carried out on site, the environmental conditions shall be subject to the conditions that can meet the on-site use of the instrument.


2) As a standard instrument for calibration, the error limit of the instrument shall be 1/3~1/10 of the error limit of the calibrated meter.


3) Although the personnel calibration is different from the verification, the personnel conducting the calibration shall also be subject to effective assessment and obtain corresponding qualification certificates. Only the certified personnel can issue calibration certificates and calibration reports, and only such certificates and reports are recognized.
