Geometrical product specifications (GPS) - General concepts - Part 1 : model for geometrical specification and verification

ISO 17450-1:2011 provides a model for geometrical specification and verification and defines the corresponding concepts. It also explains the mathematical basis of the concepts associated with the model and defines general terms for geometrical features of workpieces.ISO 17450-1:2011 defines the fundamental concepts for the GPS system in order to provide nonambiguous GPS language to be used in design, manufacturing and verification, to identify features, characteristics and rules to provide the basis for specifications, to provide a complete symbology language to indicate GPS specifications, to provide simplified symbology by defining default rules, and to provide consistent rules for verification.

Geometrical Product Specification (GPS) - General concepts - Part 1 : model for geometrical specification and verification

Dans la série des normes relatives aux concepts généraux de la spécification géométrique des produits (GPS), le présent document fournit un modèle pour la spécification et la vérification géométriques des produits. Les concepts liés aux opérateurs et incertitudes font l'objet de la NF ISO/TS 17450-2. Le présent document est un document GPS global, dont la situation dans la matrice GPS est indiquée en Annexe E.

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.
