7.1 .5 Conductor sizes 30 – 20 AWG (0.05 – 0.52 mm 2 ) need not be subjected to the secureness test in the static-heating sequence or mechanical sequence. 7.1 .6 Specimen sets shall be subjected to the test sequences using the conductor material specified in Table 3 for the one or more conductor material combinations for which the equipment wiring terminal is intended. The stress corrosion tests shall be permitted to be conducted using either copper or aluminum conductor. When an equipment wiring terminal is rated for copper-to-copper, aluminum-to-aluminum, and copper-to-aluminum (intermixed), the mechanical sequence with copper-to-aluminum conductors may be omitted. 7.1 .7 For an equipment wiring terminal intended to be used with aluminum, copper-clad aluminum, and copper wire (marked ″AL-CU″ on the equipment wiring terminal or the end use equipment), sample sets with aluminum wire and copper wire are to be subjected to the test sequence in Table 1 or Table 2. For an equipment wiring terminal intended to be used with copper-clad aluminum wire and copper wire (marked ″CC-CU″ on the equipment wiring terminal or the end use equipment), sample sets with copper-clad aluminum wire and copper wire are to be subjected to the test sequence in Table 1 or Table 2. For a terminal intended to be used with copper wire only, sample sets with copper wire are to be subjected to the test sequence in Table 1 or Table 2. 7.1 .8 Tests with aluminum wire are representative of tests with copper-clad aluminum wire. 7.1 .9 An equipment wiring terminal rated for Class 5 and 6 metric conductors (flexible stranded) shall be subjected to all test sequences using flexible metric conductors. 7.1 .1 0 For an equipment wiring terminal intended to be used with aluminum and copper conductor, specimens with aluminum conductor and copper conductor shall be subjected to the current-cycling, static-heating sequence, and mechanical sequence tests.7.1 .1 1 For an aluminum-bodied equipment wiring terminal intended to be used with copper conductor only, specimens with copper conductor shall be subjected to the current-cycling, static-heating sequence, and mechanical sequence tests. 7.1 .1 2 Tests conducted on an equipment wiring terminal with compact-stranded conductors shall represent tests with concentric and compressed stranded conductors of the same size.
