Procedure A of this test method is equivalent to the test method in the main body of ISO We have no amendments or corrections for this standard. Note 1—This test method and ISO are equivalent. Standards Subsctiption may be the perfect solution. Note 1—This test method and ISO are equivalent.

In practice, the Rockwell hardness number is derived from the following xstm We have no amendments or corrections for this standard. Indentation hardness is used as an indication of cure of some thermosetting materials at room temperature. A Rockwell hardness number c785-08 a number derived from the net increase in depth impression as the load on an indenter is increased from a fixed minor load to a major load and then returned to a minor load Procedure A.

For certain types of materials having creep and recovery, the time factors involved in applications of major and minor loads have a considerable effect on the results of the measurements. Standards Subsctiption asmt be the perfect solution. Link to Active This link will always route to the current Active version of the standard. Add to Alert PDF. Indenters are round steel balls of specific diameters.

The Rockwell Hardness test is a hardness measurement based on the net increase in depth of impression as a load is applied. The major load is applied by tripping a lever. If there are no material specifications, then the default conditions apply.
