Self adhesive tapes - Measurement of breaking strength and elongation at break
This European Standard specifies methods to measure the breaking strength and elongation at break of a self adhesive tape when it is subjected to a tensile force sufficient to cause it to break.
The breaking strength of adhesive tape is of value as an indication of its uniformity and quality, and its ability to withstand stresses during application and use.
The elongation at break of the adhesive tape is of value as an indication of its uniformity and quality as well as a rough indication of its ability to conform to curved and irregular surfaces. It is usually determined at the same time as the breaking strength.
This test method describes a procedure for testing 12 mm or 24 mm wide samples cut from supplied rolls of self adhesive tapes. Alternatively rolls of self adhesive tape up to 50 mm wide may be directly tested in their original width. In these circumstances the practical breaking strength and elongation will be typical of the manufacturer's cut edges. When newly cut sample pieces are tested, because of the better cutting of the edges, the results can be higher than would be found on commercial tape.
Klebebänder - Messung der Bruchkraft und der Reißdehnung
Rubans auto-adhésifs - Mesurage de la résistance a la rupture et de l'allongement a la rupture
La présente Norme européenne spécifie des méthodes pour mesurer la résistance a la rupture et l'allongement a la rupture d'un ruban auto-adhésif lorsqu'il est soumis a une force de traction suffisante pour provoquer sa rupture.
La résistance a la rupture d'un ruban adhésif est intéressante pour connaître l'uniformité, la qualité et l'aptitude de ce ruban a supporter des efforts au cours de l'application et en service.
L'allongement a la rupture d'un ruban adhésif est intéressant pour connaître l'uniformité et la qualité du ruban, et il donne également une indication grossiere de l'aptitude du ruban a s'adapter a des surfaces courbes et irrégulieres. L'allongement est généralement déterminé en meme temps que la résistance a la rupture.
La présente méthode d'essai décrit un mode opératoire pour soumettre a l'essai des échantillons de rouleaux de rubans auto-adhésifs de 12 mm ou 24 mm de largeur. Une autre solution consiste a soumettre a l'essai des rouleaux de ruban directement dans leur largeur initiale (au plus 50 mm). Dans ces conditions, la résistance et l'allongement a la rupture sont, en pratique, caractéristiques de la découpe des bords effectuée en usine. Lorsque les essais portent sur des échantillons fraîchement découpés, les résultats obtenus peuvent se révéler supérieurs a ceux qui l'auraient été en utilisant des rubans du commerce en raison de la meilleure découpe des bords.

EN 14410:2003 (E)3ForewordThis document (EN 14410:2003) has been prepared by Technical Committee CEN/TC 253 "Self adhesive tapes",the secretariat of which is held by AFNOR.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by September 2003, and conflicting national standards shall be withdrawn at thelatest by September 2003.This document supersedes EN 1940:1996 and EN 1941:1996.This European standard has been revised in conjunction with AFERA (Association of European self Adhesivetapes Manufacturers) in Europe and PSTC (Pressure Sensitive Tape Council) in USA with the purpose to producea standard which will be acceptable in due course by ISO.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 14410:2003
EN 14410:2003 (E)4IntroductionThe method specified in this European Standard combines the determination of breaking strength and elongationat break into one method in place of the two separate methods originally published, EN 1940 and EN 1941. Theactual test method for both is identical, only the interpretation of the results was different.Method A: Self adhesive tapes – Measurement of breaking strength and elongation at break of tapes other thanfilament tapes.Method B: Self adhesive tapes – Measurement of breaking strength of filament reinforced tapes.SIST EN 14410:2003
EN 14410:2003 (E)51 ScopeThis European Standard specifies methods to measure the breaking strength and elongation at break of a selfadhesive tape when it is subjected to a tensile force sufficient to cause it to break.The breaking strength of adhesive tape is of value as an indication of its uniformity and quality, and its ability towithstand stresses during application and use.The elongation at break of the adhesive tape is of value as an indication of its uniformity and quality as well as arough indication of its ability to conform to curved and irregular surfaces. It is usually determined at the same timeas the breaking strength.This test method describes a procedure for testing 12 mm or 24 mm wide samples cut from supplied rolls of selfadhesive tapes. Alternatively rolls of self adhesive tape up to 50 mm wide may be directly tested in their originalwidth. In these circumstances the practical breaking strength and elongation will be typical of the manufacturer’scut edges. When newly cut sample pieces are tested, because of the better cutting of the edges, the results can behigher than would be found on commercial tape.2 Terms and definitionsFor the purposes of this European Standard, the following terms and definitions apply.2.1breaking strengthability to resist breaking when subject to load under prescribed conditions2.2elongation at breakincrease in length of the adhesive tape at the time of breaking as a percentage of the original length3 Significance and useThese methods provide a means of assessing the uniformity of breaking strength and elongation at break of agiven type of pressure sensitive tape and may be used to compare one product with another.The test method may be used to determine particular backing materials or tape widths appropriate to a desired enduse.When relative strength is of interest, the testing should be on tape in the width received to avoid discrepancies asdescribed above.NOTE 1Comparison of tapes by different procedures should be avoided because test parameters such as test piecedimension or jaw speed determine the result. Different levels will produce different results for the same test tape. It is usual tofind breaking strength increasing significantly with increasing jaw speed.NOTE 2Elongation measurements become difficult to perform on stretchy materials (greater than 200 % elongation atbreak) when the ratio of test piece length to width is small (approaching 2). The results show high variability and do not allow forpractical use of this information except when one wishes to demonstrate large differences between materials.4 PrincipleThe method consists of holding the adhesive tape vertically by the two clamps of a tensile testing machine. Atensile test is carried out until the adhesive tape breaks.SIST EN 14410:2003
EN 14410:2003 (E)6Method A: A strip of tape is mounted between two clamps aligned in a straight flat plane and a force is applied at aspecified rate until the tape breaks.Method B: A strip of filament reinforced tape is applied to two drums aligned in a flat plane and a force is applied ata specified rate until the tape breaks.5 Apparatus5.1 Tensile testing machineA constant rate of extension (CRE) tension tester shall be used. The tester shall have two clamps with centres inthe same plane, parallel with the direction of the motion on the stressing clamp and so aligned that th
