Steel - Conversion of elongation values - Part 1: Carbon and low-alloy steels (ISO 2566-1:2021, Corrected version 2022-06)
This document specifies a method of converting room temperature percentage elongations after fracture obtained on various proportional and non-proportional gauge lengths to other gauge lengths.
Formula (1), on which conversions are based, is considered to be reliable when applied to carbon, carbon manganese, molybdenum and chromium molybdenum steels within the tensile strength range 300 N/mm2 to 700 N/mm2 and in the hot-rolled, hot-rolled and normalized or annealed conditions, with or without tempering.
These conversions are not applicable to:
a) cold reduced steels;
b) quenched and tempered steels;
c) austenitic steels.
These conversions are not applicable when the gauge length exceeds or where the width to thickness ratio of the test piece exceeds 20.
Stahl - Umrechnung von Bruchdehnungswerten - Teil 1: Unlegierte und niedrig legierte Stähle (ISO 2566-1:2021, korrigierte Fassung 2022-06)
Dieses Dokument legt ein Verfahren für die Umrechnung von prozentualen Dehnungswerten nach erfolgtem Bruch bei Raumtemperatur fest, bei dem Bruchdehnungswerte, die bei verschiedenen proportionalen und nicht-proportionalen Messlängen ermittelt wurden, auf andere Messlängen umgerechnet werden.
Die Gleichung (1), die den Umrechnungen zugrunde liegt, gilt als zuverlässig, wenn sie auf unlegierte Stähle, Kohlenstoff-Mangan-, Molybdän- und Chrom-Molybdän-Stahl im Zugfestigkeitsbereich von 300 N/mm2 bis 700 N/mm2 und im warmgewalzten, warmgewalzten und normalgeglühten oder geglühten Zustand, mit oder ohne Anlassen, angewendet wird.
Diese Umrechnungen sind nicht anwendbar auf:
a) kaltgewalzte Stähle;
b) vergütete Stähle;
c) austenitische Stähle.
Diese Umrechnungen sind nicht anzuwenden, wenn die Messlänge 25√(S_0 ) überschreitet oder das Verhältnis der Probenbreite zur -dicke größer als 20 ist.
Acier - Conversion des valeurs d'allongement - Partie 1: Aciers au carbone et aciers faiblement alliés (ISO 2566-1:2021, Version corrigée 2022-06)
Le présent document spécifie une méthode de conversion entre les valeurs d’allongement pour cent, à température ambiante, après rupture obtenues avec différentes longueurs entre repères, proportionnelles et non proportionnelles, et celles obtenues pour d’autres longueurs entre repères.
La Formule (1), sur laquelle les conversions sont basées, est considérée comme valable lorsqu’elle s’applique aux aciers au carbone, au carbone manganèse, molybdène et chrome molybdène dont la résistance à la traction est comprise entre 300 N/mm2 et 700 N/mm2, à l’état laminé à chaud, laminé à chaud et normalisé ou recuit, avec ou sans revenu.
Ces conversions ne sont pas applicables aux:
a) aciers laminés à froid;
b) aciers trempés et revenus;
c) aciers austénitiques.
Ces conversions ne sont pas applicables lorsque la longueur entre repères est supérieure à ou lorsque le rapport de la largeur à l’épaisseur de l’éprouvette est supérieur 20.
Jekla - Pretvarjanje vrednosti raztezkov - 1. del: Ogljikova in malolegirana jekla (ISO 2566-1:2021, popravljena različica 2022-06)
Ta dokument določa metodo za pretvarjanje odstotnih raztezkov pri sobni temperaturi ob porušitvi, pridobljenih za različne sorazmerne in nesorazmerne merilne dolžine glede na druge merilne dolžine. Formula (1), na kateri temeljijo pretvorbe, se šteje za zanesljivo, kadar se uporablja za ogljikova, ogljikovo-manganova, molibdenova in krom-molibdenova jekla v območju natezne trdnosti od 300 do 700 N/mm2 ter v vroče valjanem, vroče valjanem in normaliziranem ali žarjenem stanju, s tempranjem ali brez. Te pretvorbe se ne uporabljajo za: a) hladno valjana jekla; b) kaljena in temprana jekla; c) avstenitna jekla. Te pretvorbe se ne uporabljajo, če merilna dolžina presega 25 S0 oziroma je razmerje med širino in debelino preskušanca večje od 20.

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

Introduction
Several different gauge lengths are commonly in use for the determination of percentage elongation of
steels in tensile testing. Fixed gauge lengths of 50 mm, 80 mm, 100 mm and 200 mm are used;
proportional gauge lengths of kS are also used for flat and round test pieces, where k may be one of
a number of values, i.e. 4; 5,65; 8,16 or 11,3.
The value 56, 5 S is adopted as the internationally preferred proportional gauge length.
Arising from this choice and the existence of specifications stipulating minimum percentage elongations
on different gauge lengths, a growing need has been evident for an International Standard that could be
used to convert test results into values based on the different gauge lengths. Accordingly, this document
includes tables of conversion factors, tables of actual conversions for some of the most commonly used
gauge
