27、SO (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 c
28、ommittee 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 electr
29、otechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the m
30、ember 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 part of ISO 2039 may be the subject of patent rights. ISO shall not be held responsible fo
31、r identifying any or all such patent rights. ISO 2039-1 was prepared by Technical Committee ISO/TC 61, Plastics, Subcommittee SC 2, Mechanical properties. This third edition cancels and replaces the second edition (ISO 2039-1:1993), subclause 8.3 and annex A of which have been technically revised. I
32、SO 2039 consists of the following parts, under the general title Plastics Determination of hardness: Part 1: Ball indentation method Part 2: Rockwell hardness Annex A of this part of ISO 2039 is for information only.

33、MT+00:00 2006, Uncontrolled Copy, (c) BSI INTENRATIONAL TSANDADR IS-9302 O1:(1002)E 1 Plastics Determination of hardness Part 1: Ball indentation method 1 Scope This part of ISO 2039 specifies a method for determining the hardness of plastics and ebonite by means of a loaded ball indenter. The ball
34、indentation hardness determined by this method may provide data for research and development, quality control and acceptance or rejection under specifications. 2 Normative reference The following normative document contains provisions which, through reference in this text, constitute provisions of t
35、his part of ISO 2039. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 2039 are encouraged to investigate the possibility of applying the most recent edition of the normative document ind
36、icated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 291:1997, Plastics Standard atmospheres for conditioning and testing 3 Term and definition For the purpose
37、s of this part of ISO 2039, the following term and definition apply. 3.1 ball indentation hardness HB the quotient of the load on the ball indenter by the surface area of the impression caused by the ball indenter after a specified time of load application NOTE It is expressed in newtons per square
38、millimetre. 4 Principle The method consists of forcing a ball under a specified load into the surface of the test specimen. The depth of impression is measured under load. The surface area of the impression is computed from its depth. The ball indentation hardness is then calculated from the followi
39、ng relationship: Ball indentation hardness = Applied load/Surface area of impression EN ISO 20391:2003 Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 20 02:44:59 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 2 5 Apparatus 5.1 Hardness tester, consisting essentially of a frame with an adjustable pl
40、atform fitted with a plate to support the test specimen, an indenter with its associated fittings and a device for applying the load without impact. The tester shall also be equipped with a device to measure the depth of penetration of the indenter over a range of 0,4 mm with an accuracy of 0,005 mm
41、. The frame shall not be deformed under the maximum load by more than 0,05 mm, the deformation being measured along the main axis of the applied force. The indenter shall be a hardened and polished steel ball. The ball shall not show any deformation or damage after the test. The diameter of the ball
42、 shall be (5,0 0,05) mm. 5.2 Timing device, accurate to 0,1 s 6 Test specimens Each test specimen shall be a smooth flat sheet or block of sufficient size to minimize edge effects on the test result; for example 20 mm 20 mm. The surfaces of the test specimen shall be parallel. A thickness of 4 mm is
43、 recommended. The supported surface of the test specimen shall not show any deformation after testing. NOTE 1 If test specimens with thicknesses less than 4 mm are to be tested, it is possible to stack several test specimens on top of each other. However, hardness values obtained on stacked test spe
44、cimens and on single test specimens of the same thickness may be different. NOTE 2 Although every effort should be made to ensure the parallelism of the specimen, there are some cases, especially specimens injection-moulded from semi-crystalline thermoplastics, where it is difficult to obtain test s
45、pecimens that are exactly flat. If such slightly warped test specimens are used, part of the measured “depth of impression” will in fact correspond to the distance travelled by the indenter in pressing the test specimen down on to the supporting plate. This difficulty can be overcome by using a circ
46、ular supporting plate of diameter (10 1) mm. This diameter is also sufficiently large for perfectly flat test specimens. Also recommended is that the test specimen be placed with the flatter side towards the support plate. 7 Conditioning Condition the test specimens, prior to testing, in one of the
47、standard atmospheres specified in ISO 291. 8 Procedure 8.1 Unless otherwise specified, carry out the tests in the same atmosphere as was used for conditioning. 8.2 Place the test specimen on the supporting plate so that the test specimen is fully supported and its surfaces are perpendicular to the d
48、irection of the applied load. Apply an initial load F0 of (9,8 0,1) N at a point not less than 10 mm from the edge of the test specimen. Set the depth-indicating device to zero and then smoothly apply the test load Fm (see 8.3) over a period of 2 to 3 s. EN ISO 20391:2003 Licensed Copy: sheffieldun

If values of the depth of impression after 30 s are outside this range (either in the case of a series of test specimens or in the case of an individual t
