are mounted on hinged covers, e.g. engine covers, and the 'Seat' assembly can withstand the test forces without tilting of the hinged cover and without any latches being latched, then the latches need not be self-locking.

     3.                                     Dynamic Tests - Dummy Preparation

         1.                               A 'Hybrid III' or dummy must be installed in each seating position of the 'Seat Type' as specified in the following clauses.

             1.                         Where two rows of seats are used a 'Hybrid III' must be installed in each rear row seating position.

             2.                         Where three rows of 'Seats' are used, a 'Hybrid III' must be installed in each centre row seating position

             3.                         Where three rows of 'Seats' are used, each seating position of the rear 'Seats' must contain an unrestrained test dummy.

                 1.                   Any dummy representative of the 50th percentile adult male may be used.  For example, this may be a 'Hybrid II', 'Hybrid III' or a 'TNO 10 Dummy'.

         2.                               Each 'Hybrid III' must be restrained by the seatbelt supplied with the 'Seat'.

         3.                               Each 'Hybrid III' must be set up and positioned on a 'Seat' in accordance with the procedure set out in Clauses 7 and 8 of ADR 69/... except that:

             1.                         The knees must be set 269 mm apart as measured between the outer knee clevis flange surfaces unless the legroom prevents this, in which case the knees must be set 298 mm apart.

             2.                         The upper arms must be contacting the side of the torso.

             3.                         The palms must be placed on top of the laps.

             4.                         The feet must be placed flat on the floor.

     4.                                     Impact Simulation

         1.                               The test rig, when subjected to a velocity change of not less than 49 km/h, must achieve within 30 milliseconds a 'Forward' deceleration of at least 196 m/s2 measured in the vicinity of the corresponding 'Lap Anchorage' and must maintain that deceleration, except for periods of less than one millisecond, for not less than 20 milliseconds.

     5.                                     Measurements to be made - General

         1.                               All measurements necessary must be made with measurement systems corresponding to:

              1.    ISO 6487:2015 (Road vehicles – Measurement techniques in impact tests — Instrumentation); or

              2.    ISO 6487:2012 (Road vehicles – Measurement techniques in impact tests – Instrumentation); or

              3.    ISO 6487:2002 (Road vehicles – Measurement techniques in impact tests – Instrumentation); or

              4.    ISO 6487:2000 (Road vehicles – Measurement techniques in impact tests – Instrumentation); or

              5.    ISO 6487:1987 (Road vehicles – Measurement techniques in impact tests — Instrumentation); or

              6.     ISO 6487:1980 (Road vehicles – Techniques of measurement in impact tests – Instrumentation).

              1.                               The characteristics of the deceleration of the test rig must be determined from the accelerations measured on the rigid frame of
