22、shed cable, unless otherwise specified in the relevant cable specification. Each test specimen 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 t

23、ensile testing device. 4.2 Procedure The test piece shall be loaded into the tensile testing 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 0,10 0,03 mm. The inner conductor shal

24、l be pulled steadily at a rate not exceeding 100 mm/min until the dielectric or the outer conductor and sheath is/are 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

25、of results Dielectric adhesion shall be defined as the highest tensile reading obtained when the conductor to dielectric bond is broken.1)At draft stage.- 5 - EN 50289-3-17:2002 5 Requirements The value of the adhesion and the lengths of the dielectric shall be in accordance with the values stated i

26、n the relevant cable specification. The conductor surface must be exempt from any remaining insulating material. 6 Details to be specified The detail specification shall include: - the temperature; - the value of the adhesion; - the lengths of the dielectric. 7 Test report The test report shall incl
