BS ISO 22514-7:2012 PDF

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 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 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.
