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.

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.
