Dentistry - Test methods for rotary instruments (ISO 8325:2023)

This document specifies general test methods for rotary instruments used in dentistry. These test methods are used for measuring the dimensional characteristics, neck strength and surface roughness of rotary instruments, such as burs, cutters, polishers, grinding instruments and rotary instruments used for oral surgery such as drills and countersinks.
Specific tests are specified in the respective instrument standards, if available.
This document does not specify test methods for materials used for rotary instruments.
NOTE       For materials used for rotary instruments, see ISO 21850-1 and respective instrument standards.
This document is not applicable to endodontic instruments. For endodontic instruments, see ISO 3630-1.

Des essais spécifiques sont définis dans les normes relatives aux instruments concernés si celles-ci sont disponibles.
Le présent document ne définit pas de méthodes d’essai pour les matériaux utilisés pour les instruments rotatifs.
NOTE            En ce qui concerne les matériaux utilisés pour les instruments rotatifs, voir l’ISO 21850‑1 et les normes relatives aux instruments concernés.
Le présent document ne s’applique pas aux instruments d’endodontie. Pour les instruments d’endodontie, voir l’ISO 3630‑1.

Zobozdravstvo - Preskusne metode za vrtilne instrumente (ISO 8325:2023)

Ta dokument določa splošne preskusne metode za rotacijske instrumente, ki se uporabljajo v zobozdravstvu. Te preskusne metode se uporabljajo za merjenje dimenzijskih značilnosti, moči vratu in hrapavost površine rotacijskih instrumentov, kot so svedri, rezalniki, peskalniki, brusilni instrumenti in rotacijski instrumenti, ki se uporabljajo pri operacijah ustne votline, kot so svedri in grezilniki.
Posebni preskusi so določeni v ustreznih standardih za instrumente, če so na voljo.
Ta dokument ne določa preskusnih metod za materiale, ki se uporabljajo za rotacijske instrumente.
OPOMBA:       Za materiale, ki se uporabljajo za rotacijske instrumente, glej standard ISO 21850-1 in standarde za ustrezen instrument.
Ta dokument se ne uporablja za endodontske instrumente. Za endodontske instrumente glej standard ISO 3630-1.
