BS ISO 22514-7:2012

1   Scope This part of ISO 22514 defines a procedure to validate measuring systems and a measurement process in order to state whether a given measurement process can satisfy the requirements for a specific measurement task with a recommendation of acceptance criteria. The acceptance criteria are defined as a capability figure ( C MS ) or a capability ratio ( Q MS ).

   NOTE 1  This part of [ISO 22514](/search?q=ISO%C2%A022514) follows the approach taken in ISO/IEC Guide 98-3,  Guide to the expression of the  uncertainty  in measurement (GUM) , and establishes a basic, simplified procedure for stating and combining  uncertainty  components used to estimate a capability index for an actual  measurement process . 


 
   NOTE 2  This part of [ISO 22514](/search?q=ISO%C2%A022514) is primarily developed to be used for simple one-dimensional  measurement processes , where it is known that the method  uncertainty  and the specification  uncertainty  are small compared to the implementation  uncertainty . It can also be used in similar cases, where measurements are used to estimate process capability or process performance. It is not suitable for complex geometrical  measurement processes , such as surface texture, form, orientation and position measurements that rely on several measurement points or simultaneous measurements in several directions.
