7.6.1 Measurement system analysis
Statistical studies shall be conducted to analyse the variation present in the results of each type of measuring and test equipment system. This requirement shall apply to measurement systems referenced in the control plan.

用于控制计划中提及的测量系统。所用的分析方法及接受准则应符合顾客关于测量系统分析
