For each material, atm the samples were prepared at one source. Eight plastic materials of different hardness were evaluated with six different Barcol Impressors. This greater variation may be caused mainly by the difference in hardness between resin and? Values below 10 using the Model Impressor are inexact and should not be reported.

The data in Table 2 should not be rigorously applied to acceptance or aztm of material, as those data are speci? This standard is subject to revision at any time by the responsible technical committee and must be reviewed every?

Barcol Hardness is used to determine the hardness of both reinforced and non-reinforced rigid plastics. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.

Inspection Validating the specifications, value and safety of your raw materials, products and assets. Set the legs on the same surface or on solid material of the same thickness, so that the indentor is perpendicular to the surface being tested.

NOTE 4—Curved surfaces may be more difficult to support. Preparation and Operation of Apparatus 8. ASTM D e1.

Each laboratory obtained three test results for each material. Place the Impressor and the material to be tested or the calibration aztm on a solidly supported,? Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.


If these readings cannot be obtained, subsequent measurements are not valid. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.

Current edition approved October 10, The higher the reading the harder the material. The indicator should now read NOTE 3—Drift in readings from the maximum may occur in some materials and can be nonlinear with time. The principles of If softer supporting surfaces are used, a falsely low instrument reading may occur. Standards can be obtained from appropriate standards qstm.

This standard has been approved for use by agencies of the Department of Defense. For the materials shown, the indicated number of individual determinations were averaged to calculate each test result as follows: Any test specimen preparation, conditioning, dimensions, or testing parameters or combination thereof covered in the materials speci? Take care to avoid sliding or scraping while the indentor is in contact with the surface being tested. Within the range of hardness measured by these Impressors the Model No.
