Marginal note:Dynamic testing

• 518 (1) A mass-produced restraint system for disabled persons that is subjected to a dynamic test in accordance with section 4 of Test Method 213.3 must, when in any adjustment position for which there is no warning under subparagraph 521(1)(f)(ii),

  • (a) exhibit no complete separation of any load-bearing structural element, and no partial separation exposing a surface with

    • (i) a protrusion of more than 9.5 mm, or

    • (ii) a radius of less than 6.4 mm;

  • (b) remain in the same adjustment position during the test as it was in immediately before the test;

  • (c) except in the case of a restraint system tested with the anthropomorphic test device specified in subpart S, part 572, chapter V, title 49 of the Code of Federal Regulations of the United States (revised as of October 1, 2009), limit the resultant acceleration at the location of the accelerometer mounted in the upper thorax of the anthropomorphic test device to not more than 60 g, except for intervals of not more than 3 ms; and

  • (d) except in the case of a restraint system tested with the anthropomorphic test device specified in subpart S, part 572, chapter V, title 49 of the Code of Federal Regulations of the United States (revised as of October 1, 2009), limit the resultant acceleration of the centre of gravity of the head of the anthropomorphic test device during the movement of the head towards the front of the vehicle to not more than 80 g, except for intervals of not more than 3 ms, unless it is established that any resultant acceleration above 80 g is caused by another part of the anthropomorphic test device striking its head.

• Marginal note:Dynamic testing — levelling device

  (2) A rear-facing mass-produced restraint system for disabled persons that is subjected to a dynamic test in accordance with section 4 of Test Method 213.3 must conform to the requirements of paragraphs (1)(a) and (b) if the restraint system is equipped with a levelling device and

  • (a) the adjustment position of the levelling device is not in accordance with the manufacturer’s instructions; and
