iso 868

ISO 868:2003 is a standard for the determination of the indentation hardness of plastics and ebonite by means of a durometer of two types: type A for softer materials and type D for harder materials. The method is an empirical one for control purposes and has no simple relationship with the material's fundamental properties.

ISO 868 is an International Standard for the determination of the indentation hardness of plastics and ebonite by means of a durometer. It specifies a method for measuring the initial or final indentation hardness of softer or harder materials, and provides a procedure, equipment, and test report. It also gives equations and references for the calculation of the hardness. ISO 868:1985 is a method for the determination of the indentation hardness of plastics and ebonite by means of two types of durometers. The standard has been superseded by ISO 868:2003, which provides a more detailed and updated version of the method. International Standard IS0 868 was prepared by Technical Committee ISO/TC 61, Plastics. IS0 868 was first published in 1978. This second edition cancels and replaces the first edition, of which it constitutes a technical revision. 0 International Organization for Standardization, 1985 0 Printed in Switzerland Shore hardness is measured on plastics according to ISO 868 or ASTM D2240. The measurement procedure is simple and can be easily carried out with portable instruments. Hardness measurements to Shore are widely used for quality control purposes and belong to the macroscopic methods. specified in ISO 868 and indicated in Figure 1 (for a type A Shore durometer) and in Figure 2 (for a type D Shore durometer); likewise, verify that the maximum protrusion of the indenter beyond the base of the presser foot lies within the tolerances given in Figure 1 or 2.

A measure of the indentation resistance of elastomeric or soft plastic materials based on the depth of penetration of a conical indentor. Hardness values range from 0 (for full penetration) to 100 (for no penetration). Full penetration is between 2.46 and 2.54 mm (0.097 and 0.100 in) depending on the equipment used.
