在检定或校准工作中,需要将影响测量结果的环境参量(如温度、湿度、电压、频率等)控制在一定的范围内。在实际工作中,对计量标准技术报告、校准和测量能力(CMC)、作业指导书、证书或报告中特定测量结果进行不确定度评定时,虽然是针对同一计量标准,依据同一技术文件,选取一个稳定的被测对象对某参数在规范化条件下的常规测量结果评定,但由于应用目的不同,在环境参量的取值范围上略有差异,下面对此进行简述。
In the verification or calibration work, the environmental parameters (such as temperature, humidity, voltage, frequency, etc.) that affect the measurement result need to be controlled within a certain range. In practical work, when assessing the uncertainty of the measurement results in the standard technical report, calibration and measurement capability (CMC), work instructions, certificates or reports, although the measurement is based on the same measurement standard and the same technical document, A stable test object evaluates the normal measurement results of a parameter under normalized conditions. However, due to different purposes of application, there is a slight difference in the range of environmental parameters, which is briefly described below.
