which a 'Upper Anchor Fitting' is provided.
34.7.3.1.                    The test dummies shall each have a mass of not less than 21.4 kg or shall comply with the requirements described in technical drawings produced by the TNO (Research Institute for Road Vehicles) - Netherlands[#] for a '50th Percentile 6 Year Old Child'.
34.7.3.2.                    The test dummies shall be restrained using suitable 'Child Restraints' comprising load bearing material having an elongation of not more than 25% when subjected to a load of 11 kN, and providing for pelvic and upper torso restraint. Each pelvic restraint portion shall be attached to the 'Lap Anchorages' for the adult 'Seatbelt Assembly' for the relevant 'Seat'.  The upper torso restraint portion shall be attached to the 'Upper Anchor Fitting'.
34.7.3.3.                    The pelvic and upper torso portions of the 'Child Restraints' shall be adjusted to eliminate slack.
34.7.3.4.                    The test rig shall have a mass of not less than 380 kg and shall meet the requirements of clause 34.7.3.5 for test rig calibration. It shall comprise trolley, the test vehicle body or part thereof, and the complete 'Vehicle Rear Seat' assembly.
34.7.3.5.                    In the case of calibration prior to 'Upper Anchor Fitting' testing, the test rig, to which a mass of not less than 21.4 kg times the number of seating positions for which a 'Upper Anchor Fitting' is provided is rigidly attached, when subject to a velocity change of not less than 49 km/h, shall achieve within 30 milliseconds a forward deceleration measured in the vicinity of the corresponding 'Lap Anchorage' within the range of 235 m/s2 to 335 m/s2 and shall maintain this deceleration, except for periods of less than one millisecond, for not less than 20 milliseconds.
34.7.3.6.                    For 'Upper Anchor Fitting' testing, the test rig shall be operated in a manner identical in all operational aspects to that specified in clause 34.7.3.5 for rig calibration except that in this case the test dummies replace the inert mass. The test dummies shall be restrained in accordance with the requirements of clause 34.7.3.2.
34.7.3.7.                    Each 'Upper Anchorage' and 'Upper Anchor Fitting' shall withstand the loads imposed when tested in accordance with the dynamic test requirements of clause 34.7.3.6.

34.8.                                REQUIREMENTS FOR ISOFIX ANCHORAGES
34.8.1.                          In addition to the requirements of clauses 34.2 to 34.7, where a vehicle includes any lower anchorage, which can be engaged by the ISOFIX attachment connectors of any one of the child restraint fixtures (CRFs) defined in Appendix A of ADR 4/... on a vehicle seat:
34.8.1.1.                    each lower anchorage provided must form part of an ISOFIX anchorages system.
34.8.2.                          Except for convertible vehicles[2]:
34.8.2.1.                    each ISOFIX position must be equipped with an ISOFIX anchorages system and an ISOFIX top tether
