Set the legs on the same surface or asrm solid material of the same thickness, so that the indentor is perpendicular to the surface being tested.

Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards. For the materials shown, the indicated number of individual determinations were averaged to calculate each test result as follows: The higher the reading v2583 harder the material. Users of ashm test method should apply the principles outlined in Practice E to asfm data speci? Values below 10 using the Model Impressor are inexact and should not be reported.

The specimen is placed under the indentor of the Barcol hardness tester and a uniform pressure is applied to the specimen until the dial indication reaches a xstm. Take care to avoid sliding or scraping while the indentor is in contact with the surface being tested.
