Metallic materials - Calibration of force-proving instruments used for the verification of uniaxial testing machines
ISO 376:2004 covers the calibration of force-proving instruments used for the static verification of uniaxial testing machines (e.g. tension/compression testing machines) and describes a procedure for classifying these instruments.ISO 376:2004 generally applies to force-proving instruments in which the force is determined by measuring the elastic deformation of a loaded member or a quantity which is proportional to it.

La présente Norme internationale traite de l'étalonnage des instruments de mesure de force utilisés pour la vérification statique des machines d'essais uniaxiaux (par exemple machines d'essai de traction/compression), et décrit un mode de classification de ces instruments. L'instrument de mesure de force est défini comme étant l'ensemble allant du capteur de force jusqu'à et y compris l'appareil indicateur. La présente Norme internationale s'applique généralement aux instruments de mesure de force dans lesquels la charge est déterminée par la mesure de la déformation élastique d'un élément chargé ou par la mesure d'une grandeur proportionnelle à celle-ci.
ISO 376:2011 specifies a method for the calibration of force-proving instruments used for the static verification of uniaxial testing machines (e.g. tension/compression testing machines) and describes a procedure for the classification of these instruments. It is applicable to force-proving instruments in which the force is determined by measuring the elastic deformation of a loaded member or a quantity which is proportional to it.

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.
