Schedule 1—Test procedures
Note: See section 12.

Part 1—General

1.1 In this Schedule:
50 PAM H3 ATD (short for 50th Percentile Average Male Hybrid III Anthropomorphic Test Device) means an ATD configured to represent the 50th percentile average male.
ATD means an anthropomorphic test device.
CoG means centre of gravity.
static stability means the ability for a stationary body to resist tipping over.
Note: Key properties that affect the static stability of a quad bike are track width, wheelbase and the position of the centre of gravity.
tilt table ratio or TTR, means the tangent of the maximum tilt table angle (see clauses 6.1.10 and 6.2.11).
Note: Some other terms used in this Schedule are defined in section 4 of this instrument. For the meaning of quad bike (and types and categories of quad bike), see section 5 of this instrument.
1.2 The static stability of Type I, Category G (general use) and Category S (sports) and Type II, Category G (general) quad bikes is to be measured using a tilt table, with a 50 PAM H3 ATD simulated rider positioned in a standardised seating position as described in Part 4 of this Schedule.
1.3 The static stability of Type I, Category Y (youth) and Category T (transition) quad bikes is to be measured using a tilt table without an ATD.
1.4 The static stability factor for each direction (forward or rearward pitch, or lateral roll) is calculated as Tan (tilt table angle at 2 wheel lift).
1.5 Type I, Category G and Type II, Category G quad bikes are to be tested for each direction (forward and rearward pitch and lateral roll), and must meet the minimum performance requirements under section 16 of this instrument.
1.6 Type I, Category S, Category Y and Category T quad bikes are to be tested for lateral roll only.

Part 2—Tilt table

2.1 The tilt table must have an adjustable slope, single plane tilt‑table structure, with a range of 0° to 80° from horizontal.
2.2 The tilt table must have a surface that is rigid, flat and large enough to support all 4 quad bike wheels.
2.3 The tilt table surface must support a load cell under each of the 4 quad bike wheels.
2.4 A high friction surface is to be installed on the top surface of the downhill side load cells to prevent the low side tyres from slipping (anti‑slip tape or expanded mesh may suit).
2.5 The tilt table must 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,
