Metallic materials - Calibration and verification of static uniaxial testing machines - Part 1: Tension/compression testing machines - Calibration and verification of the force-measuring system (ISO 7500-1:2015)
ISO 7500-1:2015 specifies the calibration and verification of tension/compression testing machines.
The verification consists of:
- a general inspection of the testing machine, including its accessories for the force application;
- a calibration of the force-measuring system of the testing machine;
- a confirmation that the performance properties of the testing machine achieve the limits given for a specified class.
NOTE This part of ISO 7500 addresses the static calibration and verification of the force-measuring systems. The calibration values are not necessarily valid for high-speed or dynamic testing applications. Further information regarding dynamic effects is given in the Bibliography.
CAUTION Some of the tests specified in this part of ISO 7500 involve the use of processes which could lead to a hazardous situation.
Metallische Werkstoffe - Kalibrierung und Überprüfung von statischen einachsigen Prüfmaschinen - Teil 1: Zug und Druckprüfmaschinen - Kalibrierung und Überprüfung der Kraftmesseinrichtung (ISO 7500-1:2015)
Dieser Teil von ISO 7500 legt die Kalibrierung und Überprüfung von Zug und Druckprüfmaschinen fest.
Die Überprüfung besteht aus:
einer allgemeinen Inspektion der Prüfmaschine einschließlich der Maschinenteile für die Kraft¬auf-bringung;
einer Kalibrierung der Kraftmesseinrichtung der Prüfmaschine;
einer Bestätigung, dass die ermittelten Eigenschaften der Prüfmaschine die für eine festgelegte Klasse angegebenen Grenzwerte erreichen.
ANMERKUNG Dieser Teil von ISO 7500 betrifft die statische Kalibrierung und Überprüfung von Kraftmess¬ein-richtungen. Die Kalibrierergebnisse sind nicht notwendigerweise für Anwendungen für hochgeschwindig¬keits- oder dynamische Prüfungen gültig. Weitere Informationen bezüglich dynamischer Effekte sind in den Literaturhinweisen angegeben.
ACHTUNG — Bei einigen der in diesem Teil von ISO 7500 festgelegten Prüfungen werden Prozesse angewendet, die zu gefährlichen Situationen führen könnten.
Matériaux métalliques - Étalonnage et vérification des machines pour essais statiques uniaxiaux - Partie 1: Machines d'essai de traction/compression - Étalonnage et vérification du système de mesure de force (ISO 7500-1:2015)
ISO 7500-1:2015 spécifie l'étalonnage et la vérification des machines d'essai de traction/compression.
La vérification consiste en:
- une inspection générale de la machine d'essai, y compris ses accessoires pour l'application des forces;
- un étalonnage du système de mesure de force.
- une confirmation que les propriétés de la machine d'essai concernant ses performances atteignent les limites indiquées pour une classe spécifiée.
NOTE La présente partie de l'ISO 7500 traite de l'étalonnage et de la vérification statique des systèmes de mesure de force. Les valeurs d'étalonnage ne sont pas nécessairement valables pour les applications d'essais dynamiques ou à grande vitesse. La bibliographie donne des informations complémentaires sur les effets dynamiques.
ATTENTION ? Certains des essais spécifiés dans cette partie de l'ISO 7500 implique l'utilisation de processus qui pourrait conduire à une situation dangereuse.
Kovinski materiali - Preverjanje statičnih enoosnih preskuševalnih strojev - 1. del: Preskuševalni stroji za natezni/tlačni preskus - Preverjanje in umerjanje sistema za merjenje sile (ISO 7500-1:2015)
Ta del standarda ISO 7500 določa metodo za umerjanje in preverjanje preskuševalnih strojev za natezni/tlačni preskus.
Preverjanje je sestavljeno iz:
– splošnega pregleda preskuševalnega stroja, vključno z njegovimi priključki za uvajanje sile;
– umerjanja sistema za merjenje sile preskuševalnega stroja;
– potrditve, da zmogljivosti preskuševalnega stroja dosegajo mejne vrednosti, podane za
določen razred.
OPOMBA: Ta del standarda ISO 7500 obravnava statično umerjanje in preverjanje sistemov za natezni/tlačni
preskus. Ni nujno, da vrednosti umerjanja veljajo za uporabo pri visokih hitrostih ali dinamičnemu preskušanju. Dodatne informacije o dinamičnih učinkih so podane v bibliografiji.
POZOR – Nekateri preskusi, podani v tem delu standarda ISO 7500, vključujejo uporabo postopkov, ki lahko vodijo v nevarno stanje.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such
