The OS-1 Operating Stand provides a convenient and accurate way to perform repeated hardness
tests. The stand provides the correct testing pressure as noted in ASTM D-2240, thus eliminating human error. The OS-1 may be used with durometer types A, D, B, C, DO, O, OO and OOO.
The OS-4H Operating Stands offer all the features of the standard OS-4 stands, plus a dampening feature. The dampener lowers the durometer at the same rate for each test, resulting in superior repeatability for all durometer tests (especially in the sensitive OO and M durometer types). The OS-4H is for use with the OO, OOO and M durometer types. |
