ISO 21509:2006(E) iv © ISO 2006 – All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 21509 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical properties.
INTERNATIONAL STANDARD ISO 21509:2006(E) © ISO 2006 – All rights reserved 1Plastics and ebonite — Verification of Shore durometers 1 Scope This International Standard concerns the verification of type A and D Shore durometers used to conduct hardness tests as described in ISO 868. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 291, Plastics — Standard atmospheres for conditioning and testing ISO 868:2003, Plastics and ebonite — Determination of indentation hardness by means of a durometer (Shore hardness) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 verification all of the operations carried out in order to determine compliance of the device with the requirements of this International Standard 3.2 durometer apparatus allowing the determination of hardness by forcing an indenter into a material 4 Measuring instruments and temperature of verification The verification methods described in this document require the use of both dimensional and dynamometric instruments. NOTE Usually, the measurement uncertainty should be 1/5 of the tolerance on the value to be verified. The verification shall be conducted at an ambient temperature of 21 °C to 25 °C or 25 °C to 29 °C for tropical countries if agreed on by all parties (see ISO 291). 5 Verification of the durometer 5.1 Elements to be verified ⎯ geometry of the indenter; SIST EN ISO 21509:2015

ISO 21509:2006(E) 2 © ISO 2006 – All rights reserved ⎯ maximum protrusion of the indenter beyond the base of the presser foot; ⎯ geometry of the presser foot; ⎯ scale of the indicating device; ⎯ force exerted by the measurement spring on the indenter. 5.2 Verification of the geometry and of the maximum protrusion of the indenter beyond the base of the presser foot Using a suitable optical or mechanical device (e.g. a profile projector, a binocular optical measurement instrument, callipers or similar device), verify that the dimensions of the indenter comply with the geometry 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. Repeat the measurement three times and record each measurement for each durometer. It is recommended that the measurements be recorded in tables as shown in Table A.1 for the type A durometer and Table A.2 for the type D durometer. Dimensions in millimetres
