Copper and copper alloys - Determination of residual stresses in the border area of slit strip

This European Standard specifies a method for the determination of residual stresses in the areas adjacent to the slit edges of wrought copper and copper alloy strip, by measurement of the angle of twist, longitudinal curvature and sideways curvature of test pieces cut from strip.

Kupfer und Kupferlegierungen - Bestimmung von Restspannungen im Schnittkantenbereich von Bändern

Diese Europäische Norm legt das Verfahren zur Bestimmung von Restspannungen im Schnittkantenbereich von
Bändern aus Kupfer und Kupferlegierungen durch Messen des Winkels des Dralls, der Längsbiegung und der
Seitwärtsbiegung an Proben fest, die von Bändern abgeschnitten werden.

Cuivre et alliages de cuivre - Détermination des contraintes résiduelles sur les rives des bandes cisaillées

Domaine d'application
La présente Norme européenne spécifie une méthode pour la détermination des contraintes résiduelles sur les surfaces adjacentes aux rives cisaillées de bandes de cuivre ou d'alliage de cuivre corroyé, en mesurant l'angle de torsion, la flèche longitudinale et la flèche latérale des éprouvettes prélevées sur la bande.

Copper and copper alloys — Determination of residual stresses in the border area of slit strip.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, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden,Switzerland and the United Kingdom.SIST EN 13147:2002



Page 4EN 13147:2001IntroductionRolled strips have residual stresses caused by the production processes. The direction, distribution and level of thestresses depend on the machinery, the sequence of the selected operations and on the material, the mechanicalproperties and the dimensions of the strip.The effects of stresses adjacent to the slit edges have significant importance during later processing stages, e.g.stamping. The test method described below, is to measure these effects under special conditions.This standard is used only as a reference method for determination of residual stresses and can be applied only ifthere is agreement between the purchaser and the supplier that the method is a suitable means for determining theinfluence that the stresses detected will have on subsequent processes.1 ScopeThis European Standard specifies a metho
