- 适用范围
- This International Standard specifies the procedure to estimate measurement uncertainty from actual or claimed values of all important performance characteristics of a method under stationary conditions. It allows to assess whether or not specified values for these performance characteristics comply with the required quality of a measured value at a stated measurand value. Furthermore, it includes procedures to evaluate the applicability of the measurement method based on laboratory performance and confirmatory field test and to establish requirements on dynamic behaviour of instruments. This International Standard is applicable to measurement procedures the output of which is a defined time average.#,,#

新的一年，从移液器检查开始
Overview根据标准 DIN EN ISO 8655-2，活塞式移液器等体积测量仪必须定期检查，至少每年检查一次。用户可根据使用频率、用户数量、移液器所移取液体的腐蚀性以及既定的可接受最大允许误差等，规定更短的时间间隔。因此，对于必须按照标准DIN EN ISO 8655工作的所有实验室，移液器必须进行定期检查。...
