Abstract The set-up of Shewhart control charts control limits of average value has greater limitation for measurement standards or measuring equipments. According to the characteristic of measurement standards or measuring equipments, a simplified statistical control method is proposed. It omits the standard deviation control chart or R control chart.According to the values of standard cleviation of testing results, it provides the method to determine minimum measurement times for sub-group and the control limits of average value can set-up with standard deviation of all sub-group average values.Otherwise,it also provides the judging criterion of abnormality of average value control chart which can be simplified to three types, that reduces the workload of statistical control greatly and advantages to the popularity for measurement process statistical control method.
