Nonwovens - Test methods - Part 3: Determination of tensile strength and elongation at break using the strip method (ISO/FDIS 9073-3:2023)

Application of a force longitudinally to a test piece of a specified length and width at a constant rate of extension. Determination of values for breaking strength and elongation from the recorded force-elongation curve. In order to meet the specific needs of nonwovens, alternative requirements to those listed in ISO 5081 are established in this part of ISO 9073. These are: a) a different sampling procedure; b) a constant rate of extension (100 mm/min).

Vliesstoffe - Prüfverfahren - Teil3: Bestimmung der Höchstzugkraft und der Höchstzugkraftdehnung (ISO/FDIS 9073-3:2023)

Dieses Dokument legt ein Prüfverfahren zur Bestimmung der Höchstzugkraft und der Höchstzugkraftdehnung von vorbehandelten bzw. nassen Vliesstoffen in einem Streifenzugversuch fest. Dieses Prüfverfahren beschreibt zwei Verfahren, Option A (Breite der Messprobe: 25 mm) und Option B (Breite der Messprobe: 50 mm).
Dieses Dokument legt Verfahren unter Verwendung von Zugprüfgeräten mit konstanter Verformungsgeschwindigkeit (en: constant rate of specimen extension, CRE) fest. Geräte mit konstanter Lastgeschwindigkeit (en: constant rate of loading, CRL) werden in Anerkennung der Tatsache, dass diese Geräte weiterhin verwendet werden und nach Vereinbarung verwendet werden können, zu Informationszwecken in ISO 2062:2009, Anhang A, behandelt.

Nontissés - Méthodes d'’essai - Partie 3: Détermination de la résistance à la traction et de l'allongement à la rupture par la méthode sur bande (ISO/FDIS 9073-3:2023)

La présente partie de l'ISO 9073 prescrit une méthode pour la détermination des propriétés de résistance à la traction des nontissés par le procédé de la bande découpée. NOTE -- Des anomalies peuvent se présenter au cours des essais de nontissés réalisés à partir de filés et de nontissés à base de fibre de verre. Ceci peut nécessiter une modification de la méthode d'essai.

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

Determination of tensile strength and elongation at break
using the strip method

SAFETY WARNING — This document does not claim to address all the safety concerns, if any,

associated with its use. It is the responsibility of the user of this standard to establish appropriate

safety and health practices and determine the applicability of regulatory limitations prior to

use. It is expected that the person performing this test has been fully trained in all aspects of

this procedure.
1 Scope

This document specifies a test method for the determination of the breaking force and elongation of

nonwovens using a strip method in conditioned or wet state. This test method describes two procedures,

Option A and Option B, for carrying out nonwoven material tensile tests. These two procedures use two

types of specimens which are listed below, and three alternative types of testing machines are also

listed below. CRE is the instrument of choice.
Type of specimen:
a) Option A – 25 mm strip tensile
b) Option B – 50 mm strip tensile
Style of tensile testing machine:
a) Constant-rate-of-extension (CRE)
b) Constant-rate-of-load (CRL)
c) Constant-rate-of-traverse (CRT)

SI values are regarded as the official standard system of measurement for this standard procedure. If

other systems of measurement are used in place of SI units their values must be reported independently.

Systems of measurement must not be combined in any way, but shall be regarded and reported

separately.

NOTE INDA has sponsored studies comparing both options A and B. Studies indicated that if option A was

performed using option B’s 50 mm wide material, the result for both options would harmonize, giving the same

results, regardless of the other machine settings.

3.1
breaking force
maximum force applied to a material carried to rupture
3.2
maximum force

maximum force appearing during a test specimen carried to rupture in a tensile test under the specified

conditions
3.3
constant-rate-of-extension (CRE) tensile testing machine

tensile-testing machine provided with one clamp which is stationary and another clamp which moves

with constant speed throughout the test, the entire testing system being virtually free from deflection.

3.4
constant-rate-of-load (CRL) tensile testing machine

testing machine in which the rate of increase of the load being applied to the specimen is uniform with

time after the first 3 seconds
3.5
constant-rate-of-traverse (CRT) tensile testing machine

testing machine in which the pulling clamp moves at a uniform rate and the load is applied through the

other clamp which moves appreciably to actuate a weighing mechanism, so that the rate of increase of

load or elongation is dependent upon the extension characteristics of the specimen

3.6
cut strip test

in nonwovens, strip test in which the specimen is cut to the specified testing width, i.e. 25 or 50 mm

wide
3.7
elongation
deformation in the direction of load caused by a tensile force

Note 1 to entry: Note1 to entry Elongation is generally expressed as a ratio of the length of the stretched

material as a percentage to the length of the unstretched material. Elongation may be determined by the degree

of stretch under a specific load or the point where the stretched material breaks.

3.8
extension

increase in length of a test specimen produced by a force (in this context, stretching)
