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 maximum. Within the range of hardness measured by these Impressors the Model No.
Preparation and Operation of Apparatus 8.
If it does not, loosen the lock-nut and turn the lower plunger guide in or out to obtain a reading. The higher the reading the harder the material. Values below 10 using the Model Impressor are inexact and should not be reported. The indicator should now read Inspection Validating the specifications, value and safety of your raw materials, products and v2583.
Impressions should not be made within 3 mm 1?
The values given in parentheses are for information only. Record the maximum reading. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
NOTE 3—Drift in readings from the maximum may occur in some materials and can be nonlinear with time. Table 1 of Classi? Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.

ASTM D – BARCOL HARDNESS
NOTE 4—Curved surfaces may be more difficult to support. For the materials shown, the indicated number of individual determinations were awtm to calculate each test result as follows: The data in Table 2 should not be rigorously applied to acceptance or rejection of material, as those data are speci?
Barcol Hardness is used to determine the hardness of both reinforced and non-reinforced rigid plastics.
Take care to avoid sliding or scraping while the indentor is in contact with the surface being tested. Testing Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
On reinforced plastics, in order to maintain a variance-of-average of 0.
