Prop. 9th TCMG : Will be subject of a specific CMC-ISO/CS action around October 2000 (JC/000824)
AENOR's answer to BT N 6212 rev 3 : the corresponding ISO/TC has approved the revision of the ISO Std in order to insert European comments and have a harmonised doc. WI 00193022 shall thus be processed under VA/ISO. The TC sec. strongly requests not to delete this item (NT/01-01-03). Translation to D has been requested of DIN to be processed under VA (JC/010125).=> confirmation received from STDSUP on 2002-01-23 that this document is an ISO modified document, then not under VA.
Strukturklebstoffe - Bestimmung des dynamischen Keil-Schlag-Widerstandes von hochfesten Klebungen unter Schlagbelastung - Keil-Schlag-Verfahren (ISO 11343:1993 modifiziert)
Diese Internationale Norm legt ein dynamisches Keilschlagverfahren fest für dieBestimmung des Schlag-Schäl-Widerstandes hochfester Klebungen zwischen zwei metallischen Fügeteilen, die unter festgelegten Bedingungen hergestellt und geprüft werden. Dieses Verfahren gestattet, Metallbleche zu wählen, die in derIndustrie, z.B. für Automobilau, eingesetzt werden.
Adhésifs - Détermination de la résistance dynamique à un clivage de joints collés à haute résistance soumis aux conditions d'impact - Méthode d'impact au coin (ISO 11343:1993 modifiée)
La présente Norme européenne prescrit une méthode d'essai d'impact au coin pour la détermination de la résistance au clivage d'adhésifs à haute résistance soumis à une charge dynamique entre deux supports métalliques collés, dans des conditions spécifiées de préparation et d'essai.
La méthode permet le choix du substrat métallique en plaques correspondant aux matériaux généralement utilisés dans l'industrie, par exemple l'industrie automobile.

EN 14493:2002 (E)41 ScopeThis European Standard specifies a dynamic impact wedge method for the determination of the cleavageresistance under impact loading of high-strength adhesive bonds between two metallic adherends, when testedunder specified conditions of preparation and testing.The method allows a choice of sheet metal substrate corresponding to those materials frequently used in industry,e.g. for automotive applications.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text, and the publications are listed hereafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision.

The cleavage corresponds to the separation of the adherends bya wedge, moving at high speed, whose displacement is initiated by an impact.5 SafetyPersons using this standard shall be familiar with normal laboratory practice.This standard does not purport to address all the safety problems, if any, associated with its use.SIST EN 14493:2003
