Within the range of hardness measured by these Impressors the Model No. On reinforced plastics, in order to maintain a variance-of-average of 0. The higher the reading the harder the material. When the load is applied, bending astn spring action in the specimen should be avoided. 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.
The depth of the penetration is converted into absolute Barcol numbers. 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.

Take care to avoid sliding or scraping while the indentor is in contact with the surface being tested. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
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. Need help or have a question? If it does not, loosen the lock-nut and turn the lower plunger guide in or out to obtain a reading.
NOTE 2—It is recommended astn measurements be made with the Model Impressor when values above 90 are obtained with the Model Impressor and that measurements be made with the Model Impressor when values less than 20 are obtained with the Model No.

The principles of Current edition approved October 10, If these readings cannot be obtained, subsequent measurements are not valid. NOTE 3—Drift in readings from the maximum may occur in some materials and can be nonlinear with time.
This greater variation may be caused mainly by the difference in hardness between resin and? Data is expressed as Barcol numbers given by the instrument. For each material, all the samples were prepared at one source.
