Preface
In 2020 the European New Car Assessment Programme (Euro NCAP) will be updating its
offset frontal impact test procedure. These updates will be centred on the adoption of theThor anthropometric test device and a new barrier face for the mobile progressive
deformable barrier (MPDB).
This Technical Bulletin details the specification of the THOR dummy and certification
corridors.

THOR Specification

1.1

The THOR dummy to be used in the MPDB test shall conform to standard buildlevel B (SBL-B) and be equipped with the hardware detailed in the Humanetics
bulletin January 2018 or equivalent where equivalence has been demonstrated.
However, the following modifications shall be made.

1.2

The dummy shall be equipped with an onboard data acquisition system for bothcertification and Euro NCAP testing.

1.3
1.3.1

Spine
The THOR dummy shall be equipped with a four position spine box set to the‘slouched’ position which is equivalent to +9°.
The spine box offers only four angle adjustments, -9° erect position, 0° neutral
position, +9° slouched position and +12° super slouched position.
Alternative spine box designs may only be used where data has been provided toshow equivalence between the ‘standard’ and modified components.

1.3.2
1.3.3

1.4
1.4.1

Lower Legs
The THOR dummy shall be equipped with Hybrid III 50th percentile lower legs,
including Mil Spec shoes, HIII knee slider sensor and roller ball-bearing knees
shall be fitted. The interface between the THOR 50% upper legs and the Hybrid III
lower legs will be at the HIII ball bearing knee slider/ THOR knee.

Inspections

3.1.23.1.3
3.1.4
3.1.5

The face foam shall be inspected during regular certification of the dummy (afterevery three tests) or when the head lower performance was exceeded.
During the course of testing, normal wear on the foam has been observed by
THOR users. This wear may be in the form of small tears or abrasions on the rearsurface (Figure 1). Surface wear and small tears on the foam are normal and do not
adversely affect the performance of the head assembly.
The head assembly consists of a specially designed Confor facial foam (p/n 4721401) sandwiched between the skull assembly and the head skin (Figure 2). Thefoam can be inspected by removing the skull cap on the rear of the head (removefour screws). Then pull the dummy skin forward around the skull. The foam sits
inside the head skin and can be taken out once the skin is removed from the head.
The foam shall be replaced if multiple large cracks are present on the rear face ofthe foam, see Figure 3-left.
Assembly of face foam, head skin and skull cap is in reverse order.
No foam certification test is specified at this point, but one may be implemented at
a later date.
