Scientific-technical working group for Hardening technology and EV heat treatment, Berlin-Gharlottenbnrg, Hardenbergstr. 34. Hardness plate as a referenceBtassoxBal ") for ai & HrteewtimmaBg for hardened and tempered machine share and the like. "Hardness test plates" are my plates sus hardened steel, which is used as a reference dimension ("normal") for the Hardness determination for hardened and tempered Sssohinen- parts and the like. Serve. You FFSsag the hardship happens because of the penetration of a small kagel or pyraBiidenfSraigen penetration in all testing material. seeding average HSrte value results eich from the penetration or from the Dtmene1on of the impressions produced. In industrial production there was hardship a name for the type and aoph for the strength of the « relevant materials e. Workpiece. Ee is al99 important b etden ¢ ate * db eSBt due to the fact that in different places and mter the These requirements created test conditions everywhere be properly assessed. These This correct assessment is made by comparing the impressions with impressions that are created under the same technical circumstances on sample steel pieces that have a clearly defined hardness. Such samples are the hardness test plates. They are issued by institutes that are authorized to do so by the relevant supervisory authorities.

Bei den bisher im gebrauch befindlichen Prüfplatten hat sich praktisch gezeigt, dass nicht alle Platten die richtigen Härten haben. With the test plates previously in use, it has been practical showed that not all plates have the correct hardnesses.

Es sind nun auf Grund eingehender Forschugnen neue Härteprüfplatten entwickelt worden, für welche die Härtewerte mit dem Normalgerät bestimmt werden, das in dem zur Prüfung autorisierten Forschungsinst@tut zur Verfügung steht. Auf diese Weise wird ein echtes Bezugsmass geschaffen. Due to detailed research, there are now new hardness test plates has been developed, for which the hardness values are determined with the normal device, which is available at the research institute @ tut authorized for the examination. on in this way a real benchmark is created.

Das Ziel der Neuerung besteht darin, diesem echten Bezugsmass eine Form zu geben, die technisch sinnvoll ist und die vorteilhafte Nebenwirkung in sich sohliesst, ausreichend unterschiedlich gegenüber den bekannten härteprüfplatten zu sein. während die im Gebrauch befindlichen Härteprüpflatten als Plättchen quadratischer, rechteckiger oder kreisförmiger Gestaltung sich darstellen ist fr die Härteprufplatte gemäss der Neuerung eine Dreieoksförm kennzeichnend. Die Dreiecksform sehafft besonders gUnstige Voraoseetzungen dafür, datsa die Härteprufplatte an den Ecken des Dreiecks erfasst wird und dass auf diese Weise eine Handberahrung der Plattenoberflächen vermieden wird. Derartige Handberührungen können aati den ver- schiedensten Gründen sich nachteilig auf die Härteprüfung usw. auswirken. Dasa darüber hinaus die Dreiecksform ein auge- zeichnetes zeichnetes Hilfsmittel ist, um"das echte Bezugsmass"-das heisst ein stets gleiches Bezugsmass-von den Härteprüfplatten quadratischer, rechteckiger oder aus kreisruder Gestaltung zu unterscheiden, die nicht immer die richtigen Härtewerte ausweisen, ist ein Nebenvorteil, der für die technische Entwickung von grossem Wert ist.The aim of the innovation is to give this real reference dimension a shape that is technically sensible and has the beneficial side effect of being sufficiently different from the known hardness test plates. while the hardness test plates in use as platelets more square, rectangular or circular Design is for the hardness test plate according to Characteristic of the innovation is a three-o-ring shape. The triangle shape creates particularly favorable conditions for this, datsa die Hardness test plate is recorded at the corners of the triangle and that in this way a hand touch of the plate surfaces is avoided. Such hand touches can The most diverse reasons adversely affect the hardness test, etc. impact. In addition, the triangular shape is an eye-catching drew it The drawn aid is to distinguish "the real reference dimension" - that is, always the same reference dimension - from the hardness test plates of square, rectangular or circular design, which do not always show the correct hardness values, is a secondary advantage that is of great importance for technical development Is worth.
