17、ics 4.2.1 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 regar
18、ding terminal 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 d
19、oes not 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
20、 combination 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
21、die or 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 c
22、opper 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 Spe
23、cial tests 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.

24、065 5.2.2 Sleeve strength The insulating sleeve shall have a good grip on the terminal lug barrel before and 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
25、 a tube connected to a compressed air supply; the pressure shall be increased in 105Pa stages every 5 min up 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 lea
