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.

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

36、m the first contact between the striker and the test specimen NOTE Deflection is expressed in millimetres (mm). 3.4 energy E energy expended in deforming and penetrating the test specimen up to a deflection 1 NOTE 1 Energy is expressed in joules (J). NOTE 2 Energy is measured as the integral of the

37、force-deflection curve starting from the point of impact up to a deflection 1. 3.5 maximum force FM maximum force occurring during the test See Figures 1 to 4. NOTE Maximum force is expressed in newtons (N). 3.6 deflection at maximum force lM deflection that occurs at maximum force FM See Figures 1

38、to 4. NOTE Deflection at maximum force is expressed in millimetres (mm). 3.7 energy to maximum force EM energy expended up to the deflection l at maximum force See Figures 1 to 4.

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

41、ergy shall not be included in the puncture energy, which, therefore, is restricted to that deflection, at which the force drops to half the maximum force FM 3.10 impact failure mechanical behaviour of the material under test which may be either one of the following types (see note): a) YD b) YS c) Y

42、U yielding (zero slope at maximum force) followed by deep drawing yielding (zero slope at maximum force) followed by (at least partially) stable cracking yielding (zero slope at maximum force) followed by unstable cracking d) NY no yielding See Figures 1 to 4. 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. The force exerted on the test specimen in the direction of impact and the deflection from the centre of the test specimen
