Prüfvorrichtung zur Bestimmung des Druckverformungsrestes von Kautschuk und Elastomeren nach DIN 53 517. Test device for determining the compression set of rubber and elastomers according to DIN 53 517.

Bei den bisher gebräuchlichen Prüfvorrichtungen zur Bestimmung des Druckverformungsrest.es mußten entsprechend der vorgeschriebenen Verformung für jede Probyndicke die zugeordneten Distanzringe bereitgestellt bzw. angefertigt werden.In the test devices used to date to determine the compression set, the corresponding spacer rings had to be provided or manufactured for each sample thickness in accordance with the prescribed deformation.

Die Neuerung gemäß Anmeldung hat zum Ziel für beliebig dicke nicht genormte Probenkörper durch höheneinstellbare Gewindehülsen die vorgegebene Distanz zu erreichen und somit auf Einzeldistanzringe für jede Probendicke verzichten zu können. Unabhängig davon ermöglicht vorgenannte Vorrichtung nach wie vor die Bestimmung des Druckverformungsrestes von Normproben mit zugeordneten Distanzringen.The aim of the innovation according to the application is to achieve the specified distance for non-standard specimens of any thickness using height-adjustable threaded sleeves and thus to be able to dispense with individual spacer rings for each specimen thickness. Irrespective of this, the aforementioned device still enables the determination of the compression set of standard specimens with assigned spacer rings.

Die Vorrichtung gemäß der Neuerung ist in den Abbildungen 1-6 dargestellt.The device according to the innovation is shown in Figures 1-6 .

Die bisher gebräuchlichen Prüfvorrichtungen bestanden im wesentlichen aus 2-3 Stahlplatten (1 u. 1 a), ähnlich Teil 1 der Abb. 2 mit je 3 - 4 Distanzringen (3) gemäß Abb. 6 pro Priifebene entsprechend der zu prüfenden Probekörperdicke .The test devices used to date essentially consisted of 2-3 steel plates (1 and 1a), similar to part 1 of Fig. 2, with 3 - 4 spacer rings (3) as shown in Fig. 6 per test plane, corresponding to the thickness of the specimen to be tested.

Für den Prüfvorgang wurden die Platten gemäß teil 1 der Abb. 2 mit den Proben und den Distanz ringen (3) nach Abb. 6 mittels Schrauben zusammengespannt.For the test procedure, the plates according to part 1 of Fig. 2 were clamped together with the samples and the spacer rings (3) according to Fig. 6 by means of screws.

Beschreibung der Vorrichtung gemäß Anmeldung:Description of the device according to the application:

Die Grundplatte (2) Abb. 1-3 dient zur Aufnahme und Lagerung der höheneinstellbaren Distanzhülsen (4) Abb, 4 , wie auch von konstanten Distanzringen (5) siehe Abb■ 5. Zur Flächennutzung der Vorrichtung sind die Distanzhülsen (4) und Ringe (3 u. 5) um die Spannschrauben (6) angeordnet. Zur Höhenfeineinstellung sind die Distanzhülsen (4) im oberen sichtbaren Bereich skaliert, siehe Teil (4) Abb. 4. Entsprechend der Anzahl einstellbarer Distanzhülsen sind in deren unmittelbaren Bereich Mikrometerschrauben (7) zur Kontrolle der eingestellten Distanz- bzw. Prüfhöhe angeordnet. In den Abb. 2 und 3 sind Beispiele dargestellt, die ein Prüfen von Proben mit beliebiger Dicke und gleichzeitig auch von Normproben mit genormten Distanzringen (3) ermöglichen. In Abb. 3 ist ein Beispiel dargestellt, bei dem unter Verwendung von Distanzringen (3 u. 5) nur Probekörper nach Norm PIN 53 wie bei bisher gebräuchlichen Vorrichtungen geprüft werden können,The base plate (2) Fig. 1-3 is used to hold and store the height-adjustable spacer sleeves (4) Fig. 4 , as well as constant spacer rings (5) see Fig. 5 . To use the surface area of the device, the spacer sleeves (4) and rings (3 and 5) are arranged around the clamping screws (6). For fine height adjustment, the spacer sleeves (4) are scaled in the upper visible area, see part (4) Fig. 4 . Depending on the number of adjustable spacer sleeves, micrometer screws (7) are arranged in their immediate area to check the set distance or test height. Figs. 2 and 3 show examples that enable samples of any thickness to be tested and, at the same time, standard samples with standardized spacer rings (3). Fig. 3 shows an example in which, using spacer rings (3 and 5), only specimens according to standard PIN 53 can be tested as with previously used devices,
