Impact testers only work properly, if the impact body has a certain position in the guiding tube at the moment of impacting the test surface. In the normal position when testing flat samples, the spherical test tip is located exactly at the end of the guiding tube. When testing spherical samples with standard support rings, it is to be observed that the radii R of curvature do not drop below the values indicated. |
Standard Support Rings The standard support rings are supplied with the impact device. | Impact Devices | Model | Shape | Dimension (mm) | Min radius of curvature (mm) | | D, DC, C, E | D6 |  | ๘20 X 5.5 | 60 | | D6a |  | ๘13.5 X 5.5 | 30 | | D+15 | D6b/D+15 |  | ๘13.5X11X5.5 | 30 | | G | G6 |  | ๘30 X 7 | 100 | | G6a |  | ๘20 X 7 | 50 |
Accessory support rings The accessory support rings are available for impact devices D, DC, D+15, C and E, in the format of a set of 12. | Model | Shape | Dimension (mm) | External radii (mm) | Applications | | Z10-15 | | 20 X 20 X 7.5 | 10 - 15 | Cylindrical surfaces | | Z14.5-30 | 20 X 20 X 6.5 | 14.5 - 30 | | Z25-50 | 20 X 20 X 6 | 25 - 50 | | HZ11-13 | | 20 X 20 X 5 | 11 - 13 | Hollow-cylindrical surfaces | | HZ12.5-17 | 20 X 20 X 5 | 12.5 - 17 | | HZ16.5-30 | 20 X 20 X 5 | 16.5 - 30 | | K10-15 | | ๘20 X 7.7 | 10 - 15 | Spherical surfaces | | K14.5-30 | ๘20 X 6.7 | 14.5 - 30 | | HK11-13 | | ๘17 X 5 | 11 - 13 | Hollow-spherical surfaces | | HK12.5-17 | ๘18 X 5 | 12.5 - 17 | | HK16.5-30 | ๘20 X 5 | 16.5 - 30 | | UN | | 52 X 20 X 16 | | Universal supporting ring |
