NF EN ISO 3650
Geometrical product specifications (GPS) - Length standards - Gauge blocks
This International Standard specifies the most important design and metrological characteristics of gauge blocks with a rectangular cross section and a nominal length ln ranging from 0,5 mm to 1000 mm. Limit deviations and tolerances are stated for the calibration grade K and for the grades 0, 1 and 2 for various measuring purposes.

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.
