Foreword ISO (the International Organization for Standardization) is a worldwide federation of
15、 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. Int
16、ernational 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 t
17、he rules given in the ISO/IEC Directives, Part 3. 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 t
18、he possibility that some of the elements of this part of ISO 6603 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 6603-1 was prepared by Technical Committee ISO/TC 61,Plastics, Subcommittee SC 2,Mechanic

21、iour of rigid plastics Part 1: Non-instrumented impact testing 1?Scope This International Standard specifies methods for the determination of puncture-impact properties of rigid plastics in the form of flat test specimens, such as discs or square pieces, under defined conditions. Specimens may be mo
22、ulded directly, cut from sheets or taken from finished products. Different types of test specimens and test conditions are defined. These falling-dart methods are used to investigate the behaviour of plastic sheeting or mouldings under the impact of a striker applied perpendicular to the plane of th
23、e specimen. This part of ISO 6603 can be used if it is sufficient to characterize the impact behaviour of plastics by a threshold value of impact-failure energy based on many test specimens. ISO 6603-2 is used if a force-deflection or force-time diagram, recorded at nominally constant striker veloci
24、ty, is necessary for detailed characterization of the impact behaviour. These test methods are applicable to specimens with a thickness between 1 mm and 4 mm. NOTE?For thicknesses less than 1 mm, ISO 7765 should preferably be used. Thicknesses greater than 4 mm may be tested if the equipment is suit
25、able, but the test falls outside the scope of ISO 6603-1 and ISO 6603-2. These methods are suitable for use with the following types of material: ?rigid thermoplastic moulding and extrusion materials, including filled, unfilled and reinforced compounds and sheets; ?rigid thermosetting moulding and e
26、xtrusion materials, including filled and reinforced compounds, sheets and laminates; ?fibre-reinforced thermoset and thermoplastic composites incorporating unidirectional or non-unidirectional reinforcements such as mats, woven fabrics, woven rovings, chopped strands, combination and hybrid reinforc
27、ements, rovings, milled fibres and sheets made from pre-impregnated materials (prepregs). These methods are also applicable to specimens which are either moulded or machined from finished products, laminates and extruded or cast sheet. The test results are comparable only if the conditions of prepar
28、ation of the specimens, their dimensions and surfaces as well as the test conditions are the same. In particular, results determined on specimens of different thickness cannot be compared with one another (see annex E of ISO 6603-2:). Comprehensive evaluation of the reaction to impact stress require
29、s that determinations be made as a function of impact velocity and temperature for different material variables, such as crystallinity and moisture content. The impact behaviour of finished products cannot be predicted directly from this test, but specimens may be taken from finished products (see a
30、bove) for test by these methods. EN ISO 6603-1:2000 Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 20 02:26:40 GMT+00:00 2006, Uncontrolled Copy, (c) BSI ISO -30661:(0002)E 2? Test data developed by these methods should not be used for design calculations. However, information on the typical be
31、haviour of the material can be obtained by testing at different temperatures and impact velocities (see annex D of ISO 6603-2:), by varying the thickness (see annex E of ISO 6603-2:) and by testing specimens prepared under different conditions. Two statistical methods of test are described in this p
32、art of ISO 6603: ?Method A: staircase method (individual) (preferred) In this method, a uniform energy increment is employed during testing. The energy is decreased or increased by the uniform increment after testing each specimen, depending upon the observed result (pass or fail) for the preceding
33、test. ?Method B: group method (optional) In this method, successive groups of at least ten test specimens are tested. The impact failure energy is calculated by statistics. 2?Normative references The following normative documents contain provisions which, through reference in this text, constitute p
