Geometrical product specifications (GPS) - General concepts - Part 1: Model for geometrical specification and verification (ISO 17450-1:2011)
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.
EN ISO 17450-1:2011 - Geometrical product specifications (GPS) Part 1 - provides a formal model for geometrical specification and verification and defines the underlying concepts, terminology and mathematical basis. Published by ISO and adopted by CEN (EN ISO 17450-1:2011), this standard establishes a non‑ambiguous GPS language for use across design, manufacturing and verification workflows. It helps codify features (ideal and non‑ideal), surface and nominal models, characteristics and rules for consistent specification and measurement.
EN ISO 17450-1 is practical for:
Стандарты, упомянутые в описании
Practical uses include preparing unambiguous drawings and exchange files, defining measurement procedures, implementing CAx-to‑inspection workflows, and supporting compliance with downstream tolerancing and verification standards.
