have a tilt rate of nominally less than 1.0 degree per second (for at least the last 20° before tyre lift‑off).

Part 3—Test quad bike set‑up

3.1 The test quad bike is to be prepared to kerb mass, that is, all standard equipment fitted and vehicle fluids are to be filled to maximum capacity (engine oil, transmission and differential fluids, coolant, brakes and fuel).
3.2 The tyres are to be inflated to the manufacturer's recommended pressures. Where more than one pressure is specified, the lowest pressure is to be used.
3.3 Adjustable suspension is to be set at the value specified at the dealer delivered configuration.

Part 4—Anthropomorphic test device

4.1 For Type I Category G and Category S and Type II, Category G quad bikes, use the 50 PAM H3 ATD, clothed in form‑fitting cotton clothing and shoes equivalent to those specified in US Military Standard MIL‑S‑13192: P: Shoes, Men's, Dress, Oxford.
4.2 The ATD is to be secured to the seat so as to prevent independent movement.
4.3 The ATD pelvis is to remain parallel with the plane of the rider seat during tilting. Nominally, this is achieved by securing each leg downward toward the footrest. Hands are to be secured to the hand grips.
4.4 The ATD is to be positioned such that each hand is gripping the hand controls with the web of the hand in contact with the inner ridge of the hand grip. The arms are to be fully extended and the pelvis is to be centred laterally on the seat and located longitudinally such that the back angle (measured flat from the spine box) is vertical (±2.5°); the head roll angle is to be horizontal (±0.5°). The thighs are to be in contact with the fuel tank/cowling and the feet are to be positioned on the footrest with the leading edge of the heel in contact with the rear edge of the footrest.
4.5 The ATD pelvis angle and H point dimensions are to be recorded relative to the rear upper edge of the footrest (vertical (y) and horizontal (z) dimensions).
4.6 ATD limb joint stiffness is to be set at 1g.
Note: If the ATD cannot straddle the cowling, a pedestrian sit/stand pelvis may be required to be fitted to the device.

Part 5—Determination of centre of gravity position

5.1 Record the quad bike's wheelbase and track width (front and rear). Check against the manufacturer's documentation to confirm that the sample quad bike is within the manufacturer's tolerances.
5.2 In test condition, weigh the quad bike on a flat, level surface to obtain the 4 individual wheel masses and calculate the quad bike's longitudinal CoG and lateral CoG position.
