angle of the 'Strap' in use, when the assembly is correctly fitted for a '5th Percentile Adult Female' with the 'Seat' in the rearmost driving or riding position, except that in the case where the design provides for the centrelines of the straps to be separated when viewed normal to the plane of one 'Strap', then such angle of separation in the test may be any angle greater than 25°, and the angle of separation of the centrelines of the 'Straps' when viewed in the plane of one 'Strap' may be any angle less than l0°.
4.5.2.                              In the case of a 'Lap-Sash Belt' incorporating an 'Emergency Locking Retractor' (other than a 'Type 4N Retractor' , for which see Appendix A). where, during the wearing and retracting operations, there is relative movement between the retracting 'Strap' and the 'Sash Guide' system other than the retractor itself the tensile strength of the webbing shall not be reduced to less than 14.7 kN or 75% of the 'Dry Breaking Strength', whichever is the greater, after the retracting 'Strap' has been drawn through the 'Sash Guide' system for 50,000 cycles under the following test conditions:
4.5.2.1.                        the tensile load in all parts of the test 'Strap' during the working stroke of the 2 strokes of each cycle shall not be less than 18 N;
4.5.2.2.                        the tensile load in the test 'Strap' at one point in the cycle shall be reduced to zero;
4.5.2.3.                        the working stoke shall be not less than 200 mm;
4.5.2.4.                        the orientation of the test 'Strap' relative to the 'Sash Guide' shall be such that:
4.5.2.4.1.                  the 'Sash Guide' shall be in its design configuration except that, for 'Sash Guides' designed to pivot, the angle of the axis of rotation may vary from its design configuration provided that such variation is not greater than 5°
4.5.2.4.2.                  the part of the test 'Strap' which simulates the 'Strap' passing from the 'Sash Guide' to the next 'Sash Guide' or to the retractor, shall be in the design configuration; and
4.5.2.4.3.                  the part of the test 'Strap' which simulates the torso 'Strap' shall be pulled in a vertical plane not more than 45° or a longitudinal plane when viewed in plan, and the direction of pull in that plane shall vary over a range of not less than 65° during the working stroke of each cycle; and
4.5.2.5.                        all 'Sash Guides' for the one assembly shall be tested simultaneously.
4.5.2.6.                        The requirements of this clause shall not apply to relative movement between the 'Strap' and the retractor, at the retractor.
4.5.3.                              Buckle-Spring Fatigue Resistance
4.5.3.1.                        In the case where a spring is incorporated in the unlatching mechanism of a buckle, the
