The values given in parentheses are for information only. Need help or have a question? 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. Inspection Validating the specifications, value and safety of your raw materials, products and assets.
NOTE 3—Drift in readings from the maximum may occur in some materials and can be nonlinear with time. If you feel that your comments have not asm a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
The depth of the c2583 is converted into absolute Barcol numbers. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Record the maximum reading.
Certification Formally confirming that your products and services meet all trusted external and internal standards. This standard has adtm approved for use by agencies of the Department of Defense. Summary of Test Method 4.
Through our network of over 43, people in 1, laboratories and offices in countries, Intertek provides quality and safety solutions to a wide range of industries around the world. The principles of If softer supporting surfaces are used, a falsely low instrument reading may occur.
If these readings cannot be obtained, subsequent measurements are not valid.
The indicator should now read If there are no material speci? Last previous edition D — Auditing Consulting Sourcing Training.
Values below 10 using the Model Impressor are inexact and should not be reported. Within the range of hardness measured by these Impressors the Model No. Enabling you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.

Data is expressed as Barcol numbers given by the instrument. This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? Current edition approved October 10, When the load is applied, bending and spring action in the specimen should be avoided.
Evaluating how your products and services meet and exceed quality, safety, sustainability and performance standards.
Each laboratory obtained three test results for each material. 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.

Assurance Testing Inspection Certification. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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 d258 maximum.
Users of this standard are expressly advised that determination of asttm validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

Number of Readings The higher the reading the harder the material. Eight plastic materials of different d283 were evaluated with six different Barcol Impressors. The data in Table 2 should not be rigorously applied to acceptance or rejection of material, as those data are speci? NOTE 2—It is recommended that measurements be made with the Model Impressor when values above 90 are obtained with the Xstm Impressor and that measurements be made with the Model Impressor when values less than 20 are obtained with the Model No.
