21、odies (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 organizati
22、ons, 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
23、 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 t
24、he 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 20482 was prepared by Technical Committee ISO/TC 164, Mechanical
25、 testing of metals, Subcommittee SC 2, Ductility testing. This first edition of ISO 20482 cancels and replaces ISO 8490:1986 of which it constitutes a technical revision.

For narrow test pieces the centres of the indentations shall be in the centre of the test piece width and at least one st
33、rip width from the centre of an adjacent indentation. 7.2 The preparation of the test piece shall not produce on the edges any burr or distortion which would prevent it being placed in the machine and which could interfere with the performance of the test. 7.3 Before testing, the test piece shall no
34、t be submitted to any hammering or hot or cold working.

The test carried
35、out under controlled conditions, where required, shall be made at a temperature of (23 5)C. 9 Procedure 9.1 Determine the thickness of the test piece to the nearest 0,01 mm. 9.2 Before operating the machine, lightly grease the surfaces of the test piece which will be in contact with punch and die us
36、ing graphite grease. For the recommended composition of the graphite grease, see Annex A. By agreement, another type of lubricant may be used. 9.3 Clamp the test piece between the blank holder and the die. The blank holder force shall be approximately 10 kN. 9.4 Bring the punch, without causing shoc
37、k, into contact with the test piece. Take the measurement of penetration from this point. NOTE Before the test starts, the top of the punch should be on the same level as the upper surface of the blank holder (test point of the calibration). 9.5 Proceed with forming the indentation smoothly, at a ra
38、te between 5 mm/min and 20 mm/min for the standard test. For the test pieces with b 90 mm the rate shall be between 5 mm/min and 10 mm/min. NOTE 1 For manually operated machines, toward the end of the operation, reduce the rate to near the lower limit in order to determine accurately the moment when
39、 a through crack appears. NOTE 2 When using computer controlled testing machines, the reduction of the rate at the end of the test is not necessary, because the test result is directly given by the force/punch displacement diagram. 9.6 Stop the movement of the punch the instant a crack appears throu
40、gh the full thickness of the test piece. 9.7 Measure the depth of penetration to the nearest 0,1 mm. 9.8 A minimum of three tests shall be carried out unless otherwise specified in product standards. The value of Erichsen cupping index IE shall be the average of a minimum of three individual values,
41、 expressed in millimetres. 10 Test report The test report shall include at least the following information: a) reference to this International Standard, i.e., ISO 20482; b) identity of the test piece (test piece orientation); c) thickness of the test piece; d) type of lubricant used; e) appearance o
42、f test piece after rupture, if required; f) value of the Erichsen cupping index, IE, single values if required.

43、 grease It is known that the test results depend on the type of grease used. One representative grease that is known to be suitable has the following characteristics as determined by the relevant material specifications. The grease consists of calcium soap, refined mineral oil and flake graphite. It
44、 should be free from corrosive matter, grit resin, wax and fillers. The grease and its components should conform to the requirements shown in Table A.1.
