A number of different types of specimen and test configurations are defined. Different test paramet
29、ers are specified according to the type of material, the type of test specimen and the type of notch. 1.2 The method can be used to investigate the behaviour of specified types of specimen under the impact conditions defined and for estimating the brittleness or toughness of specimens within the lim
30、itations inherent in the test conditions. It can also be used for the determination of comparative data from similar types of material. 1.3 The method has a greater range of applicability than that given in ISO 1801and is more suitable for the testing of materials showing interlaminar shear fracture
31、 or of materials exhibiting surface effects due to environmental factors. 1.4 The method is suitable for use with the following range of materials: rigid thermoplastic moulding and extrusion materials (including filled and reinforced compounds in addition to unfilled types) and rigid thermoplastics
32、sheets; rigid thermosetting moulding materials (including filled and reinforced compounds) and rigid thermosetting sheets (including laminates); fibre-reinforced thermosetting and thermoplastic composites incorporating unidirectional or multi-directional reinforcements (such as mats, woven fabrics,
33、woven rovings, chopped strands, combination and hybrid reinforcements, rovings and milled fibres) or incorporating sheets made from pre-impregnated materials (prepregs), including filled and reinforced compounds; thermotropic liquid-crystal polymers. 1.5 Notched samples are not normally suitable for
34、 use with rigid cellular materials, long-fibre-reinforced composites or thermotropic liquid-crystal polymers. In these cases, unnotched samples may be used. 1.6 The method is suited to the use of specimens moulded to the chosen dimensions, machined from the central portion of a standard multipurpose
35、 test specimen (see ISO 3167) or machined from finished or semifinished products such as mouldings, laminates and extruded or cast sheet. 1.7 The method specifies preferred dimensions for the test specimen. Tests which are carried out on specimens of different dimensions or with different notches, o
36、r specimens which are prepared under different conditions, might produce results which are not comparable. Other factors, such as the energy capacity of the apparatus, the impact velocity and the conditioning of the specimens can also influence the results. Consequently, when comparative data are re
37、quired, these factors must be carefully controlled and recorded. EN ISO 179-1:2010 (E) DIN EN ISO 179-1:2010-11 4 1.8 The method should not be used as a source of data for design calculations. Information on the typical behaviour of a material can be obtained, however, by testing at different temper
38、atures, by varying the notch radius and/or the specimen thickness and by testing specimens prepared under different conditions. 2 Normative references The following referenced documents are indispensable for the application of this document.

47、nt (see Figure 4) 3.6 parallel impact p laminar-reinforced plastics impact with the direction of blow parallel to the plane of reinforcement (see Figure 4) 4 Principle The test specimen, supported near its ends as a horizontal beam, is impacted by a single blow of a striker, with the line of impact
48、midway between the supports, and bent at a high, nominally constant, velocity. In the case of edgewise impact with notched specimens, the line of impact is directly opposite the single notch (see Figure 1, left, and Figure 2). 5 Apparatus 5.1 Test machine The principles, characteristics and verifica
49、tion of suitable test machines are detailed in ISO 13802. ISO 13802 describes partial verification and full verification. In the case of full verification, some items are difficult to verify when the apparatus is assembled. Such verifications are assumed to be incumbent on the manufacturer. 5.2 Micrometers and gauges Micrometers and gauges capable of measuring the essential dimensions of test specimens to an accuracy of 0,02 mm are required.
