19、efinitions For the purposes of this European Standard, the definitions of EN 50290-1-2 apply. 4 Method 4.1 Preparation of test specimens Two test specimens separated by at least 300 mm shall be cut from the finished cable, unless otherwise specified in the relevant cable specification. Each test spe

20、cimen shall be prepared as shown in Figure 1. Stripping shall be done carefully so as not to effect the adhesion of the test sample. The inner conductor shall be sufficiently long to be gripped by the jaw of a tensile testing device. 4.2 Procedure The test piece shall be loaded into the tensile test

21、ing machine and test fixture as shown in Figure 2. The diameter of the hole in the test plate shall be larger than the diameter of the centre conductor or the dielectric by 0,lO f 0,03 mm. The inner conductor shall be pulled steadily at a rate not exceeding 100 mm/min until the dielectric or the out

22、er conductor and sheath idare completely removed. Sudden pulls and jerking shall be avoided. The physical handling of the test specimens shall be kept to a minimum to avoid specimen deterioration. 4.3 Expression of results Dielectric adhesion shall be defined as the highest tensile reading obtained

23、when the conductor to dielectric bond is broken. At draft stage -5- EN 50289-3-1 7:2002 5 Requirements The value of the adhesion and the lengths l? of the dielectric shall be in accordance with the values stated in the relevant cable specification. The conductor surface must be exempt from any remai

24、ning insulating material. 6 Details to be specified The detail specification shall include: - the temperature; - - the value of the adhesion; the lengths l? of the dielectric. 7 Test report The test report shall include: - temperature; - - - pass/fail criteria. the lengths l? of the dielectric, the
