29、he tear resistance of plastic film or sheet less than 1 mm thick, in the form of standard trouser-shaped test specimens, tested under defined conditions of pre-treatment, temperature, humidity, and speed of testing.The method is applicable to film and sheeting of both flexible and rigid materials, p

30、rovided that the material is not so rigid that brittle fracture occurs during the test, or so deformable, in an irreversible way, that the energy used in the deformation of the specimen legs is significant (i.e. is not negligible) with respect to the energy used in tearing.The method may not be suit

31、able for determining the tear properties of cellular sheet and film.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

35、in accordance with the terms of specifications and for research and development.EN ISO 6383-1:2015 (E) 5DIN EN ISO 6383-1:2016-05 4.2 Tear properties may vary with specimen preparation, speed of testing, and environment of testing. Consequently, when precise comparative results are required, these f

36、actors shall be carefully controlled.It is possible, in principle, to compare the tear resistance (3.2) of specimens of different materials, provided that their thicknesses do not differ by more than 10 %. However, caution is necessary in interpreting such results, since the tearing energy can vary

37、considerably with speed of testing for different materials.5 PrincipleA rectangular test specimen having a longitudinal slit extending over half its length is subjected to a tensile test on the “trouser legs” formed by the slit. The average force required to tear the specimen completely along its le

38、ngth is used to calculate the tear resistance of the material under test (see Figure 1).6 Apparatus6.1 Tensile testing machine (not pendulum type), similar to that specified in ISO 527-3, having the following characteristics.6.1.1 It shall be power driven and capable of maintaining the appropriate r

39、ate of grip separation specified in Clause 9. It is essential that the load measuring device is equipped with an autographic recording device to record the load applied to the specimen as a function of elapsed time from the start of the test.6.1.2 The grips shall be equipped with chucks designed to

40、securely hold the legs of the test specimen without slip. The chucks shall be wider than the width of the test specimen and, in order that they remain parallel to each other during a test, they shall not be mounted on swivel joints.6.2 Suitable equipment for measuring the thickness of specimens by t

41、he method described in ISO 4593. For embossed film or sheeting, the apparatus specified in ISO 4591 shall be used.7 Test specimens7.1 Test specimens shall have the shape and dimensions shown in Figure 1. The length of the slit in the centre of the specimen shall be 75 mm 1 mm.7.2 The test specimens

42、shall be cut so that the edges are smooth and free from notches. Examination with a low-power microscope is recommended to check freedom from nicks. It is important to pay particular attention to the tip of the slit in the centre of the specimen.7.3 The properties of certain types of film and sheeti

43、ng materials may vary with direction in the plane of the film (anisotropy). In such cases, it is essential to prepare two groups of test specimens with their major axes respectively parallel and perpendicular to the direction of some feature of the film or sheeting which is either visible or inferre

44、d from knowledge of the method of its manufacture.The direction of testing is defined as the direction of the long axis of the test specimen.With some types of film, different tear resistance results may be obtained for any direction of testing (for example, machine direction or transverse direction

45、) depending, for example, in the case of machine direction test specimens, on whether the tear propagation is in the direction of processing or against the process direction (see Figure 2). When this is known to occur, two groups of test specimens shall be cut in the direction of testing and slit so

46、 that results can be obtained for the two possible directions of tear propagation.EN ISO 6383-1:2015 (E) 6DIN EN ISO 6383-1:2016-05 8 Number of test specimens8.1 A minimum of five test specimens shall be tested in each of the required directions of testing.8.2 Specimens which show a tear out of line

47、 to the extent that the tear reaches one of the edges of the test specimen shall be discarded and further specimens tested (see 11.3).9 Speed of testingThe speed of testing shall be one of the following: 200 mm/min 10 %; 250 mm/min 10 %.NOTE At present time, both speeds of testing are common through

48、out the world. For the time being, both are being allowed for the purpose of this part of ISO 6383. Subsequent revisions of this part of ISO 6383 might only incorporate the testing speed of 200 mm/min.10 ConditioningUnless otherwise specified, test specimens shall be conditioned and tested in accord

49、ance with ISO 291, using atmosphere 23 C/50 %, except that when a material is known not to be sensitive to humidity, atmosphere 23 C may be used.11 Procedure11.1 Measure the thickness of the material under test using measuring devices complying with the requirements of ISO 4593. If, however, the film is very thin or if it is embossed, determine the thickness by the method of ISO 4591.11.1.1 When using measuring d
