Abstract
Verfahren zum Testen des Sprödbruchverhaltens von Chipkarten, dadurch gekennzeichnet, daß die zu testende Chipkarte (7) auf Aufnahmeschuhe (6) aufgelegt und mittels eines mittig unter der zu testenden Chipkarte (7) angeordneten Elementes (8) vorgespannt wird und daß die Chipkarte (7) stoßartig in einem Zeitfenster von 200–1000 ms mit einer Biegebelastung beaufschlagt wird, wobei eine Biegung der Chipkarte (7) in einem Winkelbereich von 150° bis 180° erfolgt.Method for testing the brittle fracture behavior of chip cards, characterized in that the chip card (7) to be tested is placed on receiving shoes (6) and biased by means of an element (8) arranged centrally under the chip card (7) to be tested, and in that the chip card (7 ) is applied in a jerky manner in a time window of 200-1000 ms with a bending load, wherein a bend of the chip card (7) takes place in an angular range of 150 ° to 180 °.
Description
Testverfahren und TestmaschineTest procedure and test machine
Die Erfindung betrifft ein Verfahren zum Testen des Sprödbruchverhaltens. Die Hersteller von Chipkarten sind bemüht, ihren Kunden ein höchstmögliches Maß an Sicherheit bei der Benutzung von Chipkarten zu bieten. Absolut ausgeschlossen werden muß ein sogenannter Sprödbruch der Chipkarten, da entstehende Splitter der Chipkarte den Benutzer verletzen können. Zwar gibt es bereits Maschinen, die Chipkarten auf Dauerbelastung z. B. Biegung prüfen, jedoch fehlt es an einem Verfahren das Aussagen über das Sprödbruchverhalten von Chipkarten liefert. Auch eine Vorrichtung zur Ausführung eines solchen Verfahrens ist dem Stand der Technik nicht entnehmbar. Das Ganze wird noch dadurch erschwert, dass das Sprödbruchverhalten bei Chipkarten nicht nur eine Materialeigenschaft ist, sondern durch weitere Sachverhalte verändert wird: Eine Chipkarte mit implantiertem Chipmodul hat z. B. ein anderes Sprödbruchverhalten als eine Karte ohne Chipmodul. Der Chipkartenhersteller benötigt reproduzierbare Aussagen zum Sprödbruchverhalten der Chipkarten.The invention relates to a method for testing brittle fracture behavior. Chip card manufacturers strive to provide their customers with the highest possible level of security when using smart cards. Absolutely excluded must be a so-called brittle fracture of the smart cards, as resulting fragments of the chip card can hurt the user. Although there are already machines that chip cards on continuous load z. B. Bend check, but lacks a method that provides information about the brittle fracture behavior of smart cards. A device for carrying out such a method can not be removed from the prior art. The whole thing is made even more difficult by the fact that the brittle fracture behavior in smart cards is not just a material property, but is changed by other circumstances: A chip card with implanted chip module has z. B. another brittle fracture behavior than a card without chip module. The chip card manufacturer needs reproducible statements on the brittle fracture behavior of the chip cards.
Aus dem ISO-Standard "International Standard ISO/IEC 10373-1:1998, First Edition 1998-12-15: Identification cards – Test methods – Part1: General characteristic tests" sind ein Prüfverfahren und eine Testvorrichtung zum Prüfen der Biegefestigkeit von Ausweiskarten bekannt, bei dem die Karten zwischen zwei Backen eingespannt werden, von denen einer beweglich ausgelegt ist. Eine Vorspannung der zu prüfenden Karte wird ebenfalls mittels der Backen vorgenommen. Eine Biegung der Karten erfolgt mit einer Frequenz von 0,5 Hz.From the ISO standard "International Standard ISO / IEC 10373-1: 1998, First Edition 1998-12-15: Identification Cards - Test Methods - Part 1: General characteristic tests" a test method and a test device for checking the flexural strength of ID cards are known in which the cards are clamped between two jaws, one of which is designed to be movable. A bias of the card to be tested is also made by means of the jaws. A bending of the cards takes place with a frequency of 0.5 Hz.

Aufgabe der Erfindung ist es daher, ein Testverfahren zu schaffen, das eine reproduzierbare Aussage zum Sprödbruchverhalten von Chipkarten ermöglicht.The object of the invention is therefore to provide a test method that allows a reproducible statement about the brittle fracture behavior of smart cards.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, dass Chipkarten mit ausreichend hoher Geschwindigkeit um eine ihrer Achsen gebogen werden. Vorzugsweise geschieht diese Biegung um die Querachse. Besonders vorteilhaft ist ein Biegewinkel zwischen 150° und 180°. According to the invention, this object is achieved in that chip cards are bent around one of their axes at a sufficiently high speed. Preferably, this bend is done around the transverse axis. Particularly advantageous is a bending angle between 150 ° and 180 °.
Um eine in einer Richtung kontrollierte Biegung erzeugen zu können wird die Chipkarte durch ein unter der Karte angebrachtes Element in einer Richtung vorgebogen, so dass die Chipkarte unter Belastung nicht zur anderen Seite ausbrechen kann.In order to be able to produce a bend controlled in one direction, the chip card is pre-bent in one direction by an element placed under the card, so that the chip card can not break out to the other side under load.
Anhand der Zeichnungen soll die Erfindung näher erläutert werden. Zum besseren Verständnis wurden Gehäuseteile, die die beweglichen Teile der erfindungsgemäßen Vorrichtung in der jeweiligen Ansicht überdecken, weggelassen.With reference to the drawings, the invention will be explained in more detail. For a better understanding, housing parts which cover the moving parts of the device according to the invention in the respective view have been omitted.
