Geometrical product specifications (GPS) - Inspection by measurement of workpieces and measuring equipment - Part 6 : generalized decision rules for the acceptance and rejection of instruments and workpieces

ISO/TR 14253-6:2012 expands the scope of decision rules to industrial situations where the default rule of ISO 14253-1 might not be economically optimal. (ISO 14253-1 provides a default decision rule having a very high probability that a measured value resulting in product acceptance also yields a product with the corresponding measurand conforming to specifications.)ISO/TR 14253-6:2012 does not address how to determine the cost of correct decisions (accepting conforming workpieces or rejecting nonconforming workpieces) or incorrect decisions (rejecting conforming workpieces or accepting nonconforming workpieces) as this is a business concern. However, the terminology and requirements to communicate and implement the particular decision rules desired by an organization are provided along with examples to guide the reader.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.

With Requirements, quickly access the main part of the normative text!
