26、hall 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 terminal lugs and in-line splices shall be designed so that: th

27、ey 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 not cause any significant burring; a reference mark identifying

28、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 combination of gauge, material and plating of the crimp barrel crim

29、ped 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 stop, the tests shall be carried out on only the smallest and

30、 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 cables and Group Al 0, AI 1, AI 2, etc. for aluminium cables.

31、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 tests 5.2.1 Crimping at low temperature Keep the components (ca

32、ble, 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. EN 3373-001:2007Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 09/05/2008 03
