19、2.1 Recommended cables The terminal lugs and in-line splices shall allow the correct connection (in accordance with EN 2242) of copper cables conforming to EN 2083 and of aluminium cables conforming to EN 3719. 4.2.2 Crimping tools The tools which are referred to in the product standards regarding t
20、erminal lugs and in-line splices shall be designed so that: they ensure the correct positioning of the crimping area; they have a full closure mechanism which ensures that the crimping cycle is fully completed; the crimping operation does not damage the terminal lug or the in-line splice and does no
21、t cause any significant burring; a reference mark identifying the gauge is made in the crimping area, if possible. 5 Tests 5.1 General Unless otherwise specified, the tests shall be selected from those in EN 2591. These tests are listed in Tables 1 and 3. The tests shall be carried out on each combi
22、nation of gauge, material and plating of the crimp barrel crimped on the appropriate section of each type of cable (material and plating), for each type of crimping tool. When a crimping barrel is designed to accommodate a range of cables for a s specific type of tool or for a type or size of die or
23、 stop, the tests shall be carried out on only the smallest and largest permitted cable sections. To rationalise the test procedures and avoid confusion between the tests for copper and aluminium cables, the tests have been grouped together, and are defined as Group Cu 0, Cu 1, Cu 2, etc. for copper
24、cables and Group Al 0, AI 1, AI 2, etc. for aluminium cables. For the purposes of these groups, copper and copper alloy cables are included within test Groups Cu 0, Cu 1, Cu 2, etc. Likewise aluminium and aluminium alloy cables are included within the test Groups AI 0, AI 1, AI 2, etc. 5.2 Special t
25、ests 5.2.1 Crimping at low temperature Keep the components (cable, terminal lugs or in-line splices and crimping tools) at a temperature of ( 15 2) C for 1 h, then crimp at that temperature. Keep the specimens at a temperature of ( 65 2) C for 1 h. Recover at (20 5) C for 1 h. Copyright Association

27、 after crimping and, when held by a fork passed around the crimping barrel, the displacement shall not be more than 1 mm under an axial load of 35 N. 5.2.3 Sealing The cable shall be placed in a tube connected to a compressed air supply; the pressure shall be increased in 105Pa stages every 5 min up
28、 to 2 105Pa and maintained at this value for 1 h (see Figure 1). The specimen shall be immersed with the end of the barrel approximately 50 mm below the water level. There shall not be any leakage in the crimping area. Key 1 60 mm to 100 mm 2 Terminal lug 3 Cable 4 Collar clamp 5 Compressed air supp

The end of the 25 mm blue flame produced by the Bunsen burner shall be applied for 20 s to
30、half the length of the insulation of the specimen. There shall be no flame or incandescence 15 s after the flame is withdrawn. 5.3 Qualification tests for crimped connections on copper cable See Table 1.

Check that: the combined section of cable/barrel size or in-line splice/crimping tool conforms; the form and position of crimping are correct; there are no major cracks o
33、r burrs on the barrel; the cable core is correctly inserted in the barrel; the cable core and insulation are not damaged; the identification marks stamped on the crimp by the die are correct (if applicable). EN 2591-102 Examination of dimensions and mass Before crimping, dimensions and masses shall
34、conform to the requirements of the product standard. EN 2591-206 Measurement of insulation resistance The insulation resistance measured between the outer surface of the insulating sleeve and the cable core shall be a minimum of 1 000 M.
