19、603-1:2000(E) l Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subje
20、ct 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. IS0 collaborates closely with the International Electrotechnical Commission (IEC
21、) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISOAEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internati
22、onal 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 IS0 6603 may be the subject of patent rights. IS0 shall not be held responsible for identifying any or all such patent rights. Interna
23、tional Standard IS0 6603-1 was prepared by Technical Committee ISORC 61, Plastics, Subcommittee SC 2, Mechanical properties. This second edition cancels and replaces the first edition (IS0 6603-1 :1985), which has been technically revised. IS0 6603 consists of the following parts, under the general
24、title Plastics - Determination of puncture impact behaviour of rigid plastics: - Part I: Non-instrumented impact testing - Patt 2: Instrumented impact testing Annex A of this part of IS0 6603 is for information only. iv STI).BSI BS EN IS0 bb03-II-ENGL 2000 1b24bb9 0848342 356 EN IS0 6603-1:2000 Plas
25、tics - Determination of puncture impact behaviour 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
26、, under defined conditions. Specimens may be moulded 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 s
27、triker applied perpendicular to the plane of the specimen. This part of IS0 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. IS0 6603-2 is used if a force-deflection or force-time diagram
28、, recorded at nominally constant striker velocity, 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 tested if the equipment is suitable, but the test falls outside the scope of IS0 6603-1 a
29、nd IS0 6603-2. For thicknesses less than 1 mm, IS0 7765 should preferably be used. Thicknesses greater than 4 mm may be These methods are suitable for use with the following types of material: - rigid thermoplastic moulding and extrusion materials, including filled, unfilled and reinforced compounds
30、 and sheets; - rigid thermosetting moulding and extrusion 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
31、, chopped strands, combination and hybrid reinforcements, 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 resul
32、ts are comparable only if the conditions of preparation 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 IS0 6603-2:-). Comprehensive
33、evaluation of the reaction to impact stress requires 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 s
34、pecimens may be taken from finished products (see above) for test by these methods. 1 STD.BS1 BS EN IS0 hh03-L-ENGL 2000 Lb24bb 0848343 292 EN IS0 6603-1:2000 Test data developed by these methods should not be used for design calculations. However, information on the typical behaviour of the materia
35、l can be obtained by testing at different temperatures and impact velocities (see annex D of IS0 6603-2:-), by varying the thickness (see annex E of IS0 6603-2:-) and by testing specimens prepared under different conditions. Two statistical methods of test are described in this part of IS0 6603: - M
36、ethod 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 test. - Method 6: g
37、roup 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 provisions of this
