A. Table 1.

B. Table 2.

  (a) When a hitch is to be tested:

    (1) Assemble the hitch in its normal configuration as recommended by the hitch manufacturer.

    (2) Attach the hitch to a non-yielding restraining fixture. The hitch-to-fixture attaching means shall be the same as the normal hitch-to-car attaching means recommended by the hitch manufacturer.

    (3) The points of hitch-to-fixture attachment shall be located in the same positions as the hitch-to-car attachment point locations recommended by the manufacturer.

    (4) Attach a ball to the ball support platform in the manner recommended by the hitch manufacturer.

  (b) Hitch Test Force Applications. With the hitch attached to the test fixture as specified in footnote(a), above, successively apply the forces designated in Table 2, as follows:

    (1) Apply the specified downward vertical force concurrently with the specified compressive longitudinal force or spring bar moment.

    (2) Apply the specified tensile longitudinal force concurrently with the specified downward vertical force.

    (3) Apply the specified compressive longitudinal force concurrently with the specified downward vertical force.

    (4) Apply the specified leftward transverse force.

    (5) Apply the specified rightward transverse force.

    (6) For hitches with weight distributing capability, apply the specified spring bar, or leveling moment, concurrently with the specified downward vertical force.

  (c) Each hitch, when tested as specified above, shall be capable of withstanding the forces applied in accordance with footnote (b), immediately above, without causing permanent deformation of the ball platform, such that the final position of the ball axis may not depart more than 5 degrees from its original, nominally vertical position.
