Leather - Measurement of leather surface - Electronic techniques (ISO 19076:2023)

This document provides a method for the measurement of the surface of leather or leather parts by the use of electronic measuring machines.
It applies to the measurement of leather (or leather parts) fulfilling the following requirements:
—    flexible leather, finished or unfinished dry leather;
—    flexible wet leather (see Annex E);
—    flexibility, such as to allow full distension on the measuring line or surface.

Leder - Messung der Oberfläche des Leders - Elektronische Verfahren (ISO 19076:2023)

Dieses Dokument legt ein Verfahren für die Messung der Oberfläche von Leder oder von Lederteilen durch die Anwendung elektronischer Messmaschinen fest.
Die Norm ist für die Messung von Leder (oder Lederteilen) anwendbar, das (oder die) die folgenden Anforderungen erfüllt (erfüllen):
   flexibles Leder, trockenes Leder mit oder ohne Zurichtung;
   flexibles nasses Leder (siehe Anhang E);
   Flexibilität, z. B. um die volle Ausdehnung auf der Messlinie oder Oberfläche zu ermöglichen.

Cuir - Mesurage de la surface du cuir - Techniques électroniques (ISO 19076:2023)

Le présent document fournit une méthode pour le mesurage de la surface du cuir ou de pièces de cuir au moyen d’appareils de mesure électroniques.
Il s’applique au mesurage du cuir (ou de pièces de cuir) satisfaisant aux exigences suivantes:
—    cuir souple, cuir sec fini ou non fini;
—    cuir humide souple (voir l’Annexe E);
—    souplesse du cuir de manière à pouvoir le distendre complètement sur la ligne/surface de mesurage.

Usnje - Merjenje usnjene površine - Elektronske tehnike (ISO 19076:2023)

Standard ISO 19076:2016 podaja metodo za merjenje površine usnja ali usnjenih delov z uporabo elektronskih merilnih strojev.
Uporablja se za merjenje usnja (ali usnjenih delov), pri čemer izpolnjuje naslednje zahteve:
– upogljivo usnje, obdelano ali neobdelano, suho ali mokro usnje;
– upogljivost: takšna, ki omogoča popolno razteznost na merilni črti/površini.

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
