Motor Vehicle Safety Regulations — 210.2
 Requirements (13) A lower universal anchorage system installed in a row of designated seating positions shall not separate completely from the vehicle seat or seat anchorage or the structure of the vehicle when tested (a) subject to subsection (15), by pulling with a force of 15 000 N, which force is (i) applied by means of a test device shown in Figures 7 and 8 that is installed using both the associated user-ready tether anchorage and the lower universal anchorage system as a child restraint system would be installed in accordance with the vehicle manufacturer’s instructions, (ii) applied in a forward direction parallel to the vehicle’s vertical longitudinal plane through the X point on the test device, starting with a pre-load force of 500 N, (iii) applied initially, along a line above the horizontal line, at an angle of 10° ± 5° to it, (iv) attained within 30 seconds, at any onset force rate of not more than 135 000 N/s, and (v) maintained at a level of 15 000 N for a minimum of one second; and (b) by pulling with a force of 5 000 N, which force is (i) applied by means of a test device shown in Figures 7 and 8 that is installed as a child restraint system would be installed in accordance with the vehicle manufacturer’s instructions using both the user ready tether anchorage and the lower universal anchorage system or, at the manufacturer’s option, using only the lower universal anchorage system, (ii) applied along a vertical longitudinal plane that is at an angle of 75º ± 5º to either side of a vertical longitudinal plane that is parallel to the vehicle’s longitudinal centre line, through the X point on the test device, starting with a pre-load force of 500 N, (iii) applied initially, along a horizontal line or along any line below or above that line that is at an angle to that line of not more than 5°, (iv) attained within 30 seconds, at any onset force rate of not more than 135 000 N/s, and (v) maintained at a level of 5 000 N for a minimum of 1 second. (14) When a force of 5 000 N is applied in accordance with paragraph (13)(b), the lower universal anchorage system shall not permit the X point on the test device to be displaced in the direction of the applied force by more than 125 mm if the test device is installed in an outboard designated seating position or by more than 150 mm if the test device is installed in an inboard designated seating position. (15) A lower universal anchorage system installed in a designated seating position that is not equipped with an associated user-ready tether anchorage shall be tested by the application of a force of 11 000 N that is (a) applied by means of a test device shown in Figures 7 and 8 that is installed using only the lower universal anchorage system; (b) applied in a forward direction parallel to the vehicle’s vertical longitudinal plane through the X point on the test device, starting with a pre-load force of 500 N; (c) applied initially, along a line above the horizontal line, at an angle of 10° ± 5° to it; (d) attained within 30 seconds, at any onset force rate of not more than 135 000 N/s; and (e) maintained at a level of 11 000 N for a minimum of one second. Test Requirements (16) If a bench seat in a bus or a row of designated seating positions in another vehicle has more than one lower universal anchorage system and a distance of 400 mm or more, measured in accordance with Figure 9, separates the midpoints of any adjacent designated seating positions, the force referred to in subsection (13) or (15) shall be applied simultaneously to each anchorage system in the manner specified in that subsection. (17) The strength requirement tests shall be carried out under the following conditions: (a) the vehicle seat is installed in the vehicle; (b) the vehicle seat is adjusted to its full rearward and full downward position; (c) the vehicle seat back is adjusted in the nominal design riding position; (d) the head restraints, if installed at a designated seating position that is
