using new conductors each time, except for the last time, when the conductors used for the last but one insertion are clamped at the same place For each insertion, the conductors shall be either pushed as far as possible into the terminal or shall be inserted to ensure that the connection is adequate After each insertion, the conductor is twisted through 90° in an axial direction and then subjected to a pull force of 35 N; the pull force is applied without jerks, for min, in the direction of the axis of the conductor space If the terminal is declared as suitable for two or more conductors, the appropriate pull force is applied consecutively to each conductor During the application of the pull force, the conductor shall not come out of the terminal After these tests, neither
