The protection of the occupants in the event of a lateral collision
1 Scope
This standard specifies the requirements and test procedures for lateral collision of vehicles, as well as the modification of vehicle type, three-dimensional H point machine, mobile deformable barrier and side impact dummy.
This standard is applicable to M1 and N1 categories of vehicles where the R point of the lowest seat is not more than 700mm from ground level when the vehicle is in the condition corresponding to the reference mass.

3 Terms and definitions
For the purpose of this standard, the following terms and definitions apply.
3.1
vehicle type
a category of power-driven vehicles which do not differ in such essential respects as:
3.1.1 The length, width and ground clearance of the vehicle, in so far as they have a negative effect on the performance prescribed in this standard;
3.1.2 The structure, dimensions, lines and materials of the side walls of the passenger compartment in so far as they have a negative effect on the performance prescribed in this standard;
3.1.3 The lines and inside dimensions of the passenger compartment and the type of protection system, in so far as they have a negative effect on the performance prescribed in this standard;
3.1.4 The sitting of the engine (front, rear or centre);
3.1.5 The unladen mass, in so far as they have a negative effect on the performance prescribed in this standard;
3.1.6 The optional arrangements and interior fittings in so far as they have a negative effect on the performance prescribed in this standard;
3.1.7 The type of front seat(s) and position of R point in so far as they have a negative effect on the performance prescribed in this standard.
3.2
passenger compartment
space for occupant accommodation, bounded by the roof, floor, side walls, doors, outside glazing and front bulkhead and the plane of the rear compartment bulkhead or the plane of the rear-seat back support
3.3
R point
reference point specified by the vehicle manufacturer which:
3.3.1 Has co-ordinates determined in relation to the vehicle structure;
3.3.2 Corresponds to the theoretical position of the point of torso/thighs rotation (H point) for the lowest and most rearward normal driving position or position of use given by the vehicle manufacturer for each seating position specified by him.
3.4
H point
as established by Appendix I to Annex A of this standard
3.5
capacity of the fuel tank
fuel-tank capacity as specified by the vehicle manufacturer
3.6
transverse plane
a vertical plane perpendicular to the median longitudinal vertical plane of the vehicle
3.7
protective system
devices intended to restrain and/or protect the occupants
3.8
type of protective system
a category of protective devices which do not differ in such essential respects as their:
a) technology;
b) geometry;
c) constituent materials.
3.9
reference mass
the unladen mass of the vehicle increased by a mass of 100kg (that is the mass of the side impact dummy and its instrumentation)
3.10
unladen mass
mass of the vehicle in running order without driver, passengers or load, but with the fuel tank filled to 90% of its capacity and the usual set of tools and spare wheel on board, where applicable
3.11
mobile deformable barrier
the apparatus with which the test vehicle is impacted. It consists of a trolley and an impactor
3.12
impactor
a crushable section mounted on the front of mobile deformable barrier
3.13
trolley
a wheeled frame free to travel along its longitudinal axis at the point of impact. Its front part supports the impactor
4 Requirements
4.1 General requirements
The vehicle shall undergo a test in accordance with Annex B hereto. The test will be carried out on the driver’s side
unless asymmetric side structures, if any, are so different as to affect the performance in a side impact. In that case either of the alternatives in 4.1.1 or 4.1.2 may be used by agreement between the manufacturer and test authority.
4.1.1 The manufacturer will provide the authority responsible for approval with information regarding the compatibility of performances in comparison with the driver’s side when the test is being carried out on that side.
4.1.2 The approval authority, if concerned as to the construction of the vehicle, will decide to have the test performed on the side opposite the driver.
4.2 Performance criteria
4.2.1 The performance criteria, as determined for the collision test in accordance with Annex B hereto shall meet the following requirements:
4.2.1.1 The head performance criterion (HPC) shall be less than or equal to 1,000; when there is no head contact, then the HPC shall not be measured or calculated but recorded as "No Head Contact."
