Metallic materials - Charpy pendulum impact test - Part 3: Preparation and characterization of Charpy V-notch test pieces for indirect verification of pendulum impact machines (ISO 148-3:2016)

ISO 148-3:2016 specifies the requirements, preparation and methods for qualifying test pieces used for the indirect verification of pendulum impact testing machines in accordance with ISO 148‑2.
It specifies notched test pieces with nominal dimensions identical to those specified in ISO 148‑1; however, the tolerances are more stringent.
NOTE 1       The chemical composition or heat treatment, or both, are varied according to the energy level desired.
NOTE 2       Reference test pieces are qualified on reference pendulum impact testing machines which are also described in this part of ISO 148.

Metallische Werkstoffe - Kerbschlagbiegeversuch nach Charpy - Teil 3: Vorbereitung und Charakterisierung von Charpy-V-Referenzproben für die indirekte Prüfung der Prüfmaschinen (Pendelschlagwerke) (ISO 148-3:2016)

Dieser Teil von ISO 148 legt Anforderungen, Vorbereitung und Verfahren zum Nachweis der Eignung der Proben für die indirekte Überprüfung von Pendelschlagwerken nach ISO 148-2 fest.
Es werden gekerbte Proben mit Nennmaßen festgelegt, die den in ISO 148-1 festgelegten Maßen ent¬sprechen, wobei die Toleranzen jedoch enger sind.
ANMERKUNG 1   Die chemische Zusammensetzung oder/und die Wärmebehandlung wird/werden in Abhängigkeit von der gewünschten Energiestufe variiert.
ANMERKUNG 2   Referenzproben werden auf Referenz Pendelschlagwerken qualifiziert, die in diesem Teil von ISO 148 ebenfalls beschrieben werden.

Matériaux métalliques - Essai de flexion par choc sur éprouvette Charpy - Partie 3: Préparation et caractérisation des éprouvettes Charpy à entaille en V pour la vérification indirecte des machines d'essai mouton-pendule (ISO 148-3:2016)

ISO 148-3:2016 couvre les exigences, la préparation et les méthodes de qualification des éprouvettes utilisées pour la vérification indirecte des machines d'essai de flexion par choc (moutons-pendules) conformément à l'ISO 148‑2.
Elle décrit les éprouvettes à entaille, de dimensions nominales identiques à celles spécifiées dans l'ISO 148‑1. Cependant, les tolérances sont plus serrées.
NOTE 1       La composition chimique ou le traitement thermique, ou les deux, sont variables selon le niveau d'énergie de rupture choisi.
NOTE 2       Les éprouvettes de référence sont qualifiées sur des moutons-pendules de référence qui sont également décrits dans le présent document.

Kovinski materiali - Udarni preskus po Charpyju - 3. del: Priprava in ugotavljanje značilnosti V-zareznih preskušancev po Charpyju za posredno preverjanje udarnih naprav (ISO 148-3:2016)

Ta del standarda ISO 148 določa zahteve, priprave in metode za kvalificirane preskušance,
ki se uporabljajo za posredno preverjanje naprav za udarno preskušanje v skladu s standardom ISO 148-2.
Določa zarezne preskušance z nazivnimi merami, ki so enake podanim meram v standardu ISO 148-1,
vendar so dovoljena odstopanja strožja.
OPOMBA 1: Kemijska sestava ali toplotna obdelava (ali oboje) se spreminjajta glede na želeno raven energije.
OPOMBA 2: Referenčni preskušanci so kvalificirani na referenčnih napravah za udarno preskušanje, ki so prav tako opisane v tem delu standarda ISO 148.

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 patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
