The work of preparing International Standa
23、rds is normally carried out through IS0 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 cornmittee. International organizations, governmental and non-governmental, in liaison with ISO, also ta
24、ke part in the work. IS0 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 ISOAEC Directives, Part 3. Draft International Standards adopted by
25、 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 the possibility that some of the elements of this part of IS0 6603 may be the subject of pa
26、tent rights. IS0 shall not be held responsible for identifying any or all such patent rights. International Standard IS0 6603-2 was prepared by Technical Committee ISOTTC 61, Plastics, Subcommittee SC 2, Mechanical properties. This second edition cancels and replaces the first edition (IS0 6603-2:19
27、89), which has been technically revised. IS0 6603 consists of the following parts, under the general title Plastics - Determination of puncture impact behaviour of rigid plastics: - Part 1 : Non-instrumented impact testing - Part 2: Instrumented impact testing Annexes A to E of this part of IS0 6603

29、ure impact properties of rigid plastics, in the form of flat specimens, using instruments for measuring force and deflection. It is applicable if a force-deflection or force-time diagram, recorded at nominally constant striker velocity, is necessary for detailed characterization of the impact behavi
30、our. IS0 6603-1 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. It is not the purpose of this part of IS06603 to give an interpretation of the mechanism occurring on every particular point of
31、 the force-deflection diagram. These interpretations are a task for scientific research. NOTE See also clause 1 of IS0 6603-1:2000. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of IS0 6603. For d
32、ated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of IS0 6603 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below.

35、of impact NOTE Impact velocity is expressed in metres per second (m/s). 1 3.2 force F force exerted by the striker on the test specimen in the direction of impact NOTE Force is expressed in newtons (N). 3.3 deflection 1 relative displacement between the striker and the specimen support, starting fro

40、 and note 2. NOTE 1 Puncture energy is expressed in joules (J). NOTE 2 When testing tough materials, a transducer mounted at some distance from the impacting tip may record frictional force acting between the cylindrical pait of the striker and the punctured material. The corresponding frictional en

NOTE Comparison of Figures 2 and 3 show
43、s puncture deflection lp and puncture energy Ep are identical for the failure types YS and YU.

48、ly uniform velocity. The resulting force-deflection or force-time diagram is recorded electronically. The test specimen may be clamped in position during the test. The force-deflection diagram obtained in these tests records the impact behaviour of the specimen from which several features of the beh
49、aviour of the material may be inferred. 5 Apparatus 5.1 Testing device, consisting of the following essential components: - energy carrier, which may be inettial-mass type or hydraulic type (see 5.1 .l); - striker, which shall be lubricated; - specimen support with a recommended clamping device. The test device shall permit the test specimen to be punctured at its centre, perpendicular to its surface at a nominally constant velocity.
