  • (i) not release when a force of less than 40 N is applied, and

  • (ii) release when a force of at least 40 N but not more than 62 N is applied;

• (b) under the conditions set out in section 5 of Test Method 213.1, release when a force of not more than 71 N is applied;

• (c) conform to the requirements of S4.3(d)(2) of TSD 209, except that the surface area of a belt buckle designed for push-button application must be at least 385 mm²;

• (d) conform to the requirements of S4.3(g) of TSD 209; and

• (e) not release during the dynamic tests specified in section 4 of Test Method 213.1.

Marginal note:Webbing

310. Any webbing that is designed to secure an infant restraint system to a user-ready tether anchorage or to a lower universal anchorage system, or to restrain an infant within the restraint system, must

• (a) when tested in accordance with S5.1(b) of TSD 209, before being tested for resistance to abrasion as specified in S5.1(d) or S5.3(c) of TSD 209, for resistance to light as specified in S5.1(e) of TSD 209 or for resistance to micro-organisms as specified in S5.1(f) of TSD 209, have a breaking strength of

  • (i) at least 15 000 N in the case of webbing designed to secure the restraint system to the user-ready tether anchorage or to the lower universal anchorage system, or

  • (ii) at least 11 000 N in the case of webbing designed to restrain an infant within the restraint system;

• (b) when tested in accordance with S5.1(b) of TSD 209, after being tested for resistance to abrasion as specified in S5.1(d) or S5.3(c) of TSD 209, have a breaking strength of at least 75% of its initial breaking strength;

• (c) conform to the requirements of S4.2(e) and (f) of TSD 209 and subsections 209(3) to (6) of Schedule IV to the Motor Vehicle Safety Regulations; and

• (d) if contactable by the torso when the restraint system is tested in accordance with section 4 of Test Method 213.1, have a width of not less than 38 mm, measured as specified in S5.1(a) of TSD 209.

Marginal note:Contactable surfaces

311. Every infant restraint system must provide

• (a) for the support of the infant’s back, a continuous surface that is flat or concave and has an area of not less than 54 800 mm²; and

• (b) for the support of the sides of the infant’s torso, continuous surfaces that are flat or concave and have an area of not less than 30 500 mm² each.

Marginal note:Rigid structural elements

312. Any rigid structural element underlying a contactable surface of an infant restraint system must not have

• (a) a protrusion, with any padding or flexible overlay material removed, of more than 9.5 mm; or

• (b) an exposed edge with a radius of less than 6.4 mm.
