Inspection of tolerances of plain workpieces. Limit gauges. Tolerances and permissible wear of manufacture limit gauges up to 500 mm.
Dans la série de normes relatives à la vérification des tolérances de pièces lisses, le présent document concerne les calibres à limites utilisés en fabrication jusqu'à 500 mm, pour lesquels il fixe les tolérances et dimensions limites d'utilisation admise.
Dans la série de normes relatives à la vérification des tolérances de pièces lisses, le présent document concerne les calibres à limites utilisés en fabrication jusqu'à 500 mm, pour lesquels il fixe les tolérances et dimensions limites d'utilisation admise.
La présente norme précise - la position et la valeur des zones de tolérance, et - les limites d'usure admise des parties mesurantes des calibres à limites en acier définis par la norme NF E 02-201 "Calibres à limites - Généralités" et utilisés pour la FABRICATION des pièces lisses.
ISO 1938-1:2015 specifies the most important metrological and design characteristics of plain limit gauges of linear size. ISO 1938-1:2015 defines the different types of plain limit gauges used to verify linear dimensional specifications associated with linear size. ISO 1938-1:2015 also defines the design characteristics and the metrological characteristics for these limit gauges as well as the new or wear limits state Maximum Permissible Limits (MPLs) for the new state or wear limits state for these metrological characteristics. In addition, ISO 1938-1:2015 describes the use of limit gauges. It covers linear sizes up to 500 mm.
ISO 1938-2:2017 specifies the most important metrological and design characteristics of reference disk gauges. ISO 1938-2:2017 covers linear sizes of the gauge up to 500 mm.

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.
