Rockwell^® Accessories

---

Rockwell tester accessories are available to accommodate a variety of specimen types and geometries. Anvils and fixtures help ensure accurate results by supporting the specimen during the application of the test load. Specimen support is critical in Rockwell testing due to the fact that the method involves depth measurement. Any specimen movement is transferred to the indenter and the measurement system, resulting in an error being introduced into the test. With the precise nature of the test (keeping in mind that one Rockwell point on the regular scale equals 0.002 mm or 0.00008 of an inch) a movement of only 0.001 of an inch could cause an error of over 10 Rockwell points. The supporting fixture should be selected to match the specimen geometry and to provide full and uncompromised support. Rockwell anvils are compatible with most original manufactured Wilson Rockwell hardness testers. A selection of some of the more common Rockwell accessories is provided below.
