1. Transmitted by the experts from OICA
IWVTA-SGR
Transposition of IWVTA into national/regional WVTA This document updates SGR (submitted by OICA and Japan) in view of the decision taken at the 21st meeting of SGR0 to use the terminology “IWVTA class/IWVTA type” instead of “vehicle type/IWVTA type” which had been proposed earlier. All concepts are unchanged.

2. Background
The concept of “IWVTA class/IWVTA type” in UN-R0 is different from that of “vehicle type” which is commonly used in national / regional type approval schemes.
Therefore, guidance concerning how the “IWVTA class/ IWVTA type” in UNR0 can be transposed into the "vehicle type" in national / regional type approval is necessary.
This presentation offers such guidance using three concrete examples, namely Australia, the European Community, and Japan.

Agenda
Part 1: Type definition
Part 2: Transposition of IWVTA
into EC-WVTA
into Japanese WVTA
into Australian WVTA

4. Type definition in UN Regulations
UN R-0 has a 2-level concept
IWVTA class: vehicles which share certain design characteristics (cf. Annex 7, Paragraph 1.1)
IWVTA type: vehicles within the same vehicle type which share the same level of conformity to the technical requirements of R-0 (cf. Annex 7, Paragraph 1.2)
Other UN Regulations use the concept of vehicle type based on the design characteristics of the concerned vehicle system, e.g.
Vehicle type with respect to the braking system (cf. 2.2 of UN R-13H)
Vehicle type with respect to the seats (cf. 2.2 of UN R-17)
Vehicle type with respect to pedestrian protection (cf of UN R-127)
Each definition of vehicle type is based on certain common design characteristics in accordance with the technical purpose of respective UN Regulation.
Vehicle type definitions in UN Regulations differ from each other to meet the technical purpose of each Regulation

5. The relation between IWVTA class and IWVTA type
“Beetle with ESC”
“Beetle without ESC”
An IWVTA class shall consist of at least one IWVTA type (UN R0, Annex 7, paragraph )

6. Use of Type in hierarchical approvals (1 of 4)
If a type approval according to a UN Regulation makes use of type approvals to other UN Regulations then it must be assured that all systems/components/variants are covered
Existing example: Installation of lighting devices UN R-48
Note: the same concept applies for UN R-0
And: the same concept applies for transposition of IWVTA into national/regional WVTA
Approval of vehicle type to UN R-48

Direction Indicator
UN R-112 or 123
Approval of LED Headlamp
UN R-6
Approval of LED direction indicator …
UNR-112 Approval of H7-Headlamp
UN R-6
Approval of filament lamp direction indicator

7. Use of Type in hierarchical approvals (2 of 4)
It is also possible that the same hierarchically lower-level approval (e.g. component) is used in different hierarchically higher-level approvals (e.g. vehicle installation), example:
direction indicator in rear view mirror approved to UN R-6
The same rear view mirror is used in different vehicle types
Approval of vehicle type #1 to UN R-48
Approval of vehicle type #2 to UN R-48 …
UN R-6
Approval of LED direction indicator …

8. Use of Type in hierarchical approvals (3 of 4)
IWVTA #1
IWVTA #2
R13-H
Approval of the braking system
In the same sense it is possible that the same lower-hierarchical-level approval (R13-H) is used in different higher-hierarchical-level approvals for IWVTA.

11. Transposition of IWVTA into national/regional WVTA
The application for national/regional WVTA follows the type definition of that country/region
3 cases are possible
IWVTA type is defined as the national/regional WVTA type  1 IWVTA will be used for 1 national WVTA
IWVTA type is “larger” (=contains more variants) than the national/regional WVTA type  1 IWVTA will be used for several national WVTAs
IWVTA type is “smaller” (=contains less variants) than the national/regional WVTA type  several IWVTAs are needed for 1 national WVTA

when the manufacturer uses the floor portion
of the body structure as well as the essential
constituent elements forming the front part
of the body structure located directly in front
of the windscreen bay, in the construction of
different kinds of bodywork (for example a
saloon and a coupe), those vehicles may be
considered as belonging to the same IWVTA
class.

15. Type definition in the EU
The definition of vehicle type is identical to that of the IWVTA class in UN R-0
EC-WVTA does not need the concept of IWVTA type (It is not necessary since EC-WVTA does not foresee a concept like L-IWVTA)
Therefore, variants and versions are directly contained in the EC vehicle type
Due to the identical definition of vehicle type it is likely that one IWVTA will be transposed into one EC-WVTA
In case the EU should chose to not only accept U-WVTA but also a certain level of L-IWVTA in the future, it is also possible that e.g. a U-IWVTA and an L-IWVTA could be used within the same EC-WVTA

22. Type definition in Australia
Motor Vehicle Standards Regulations
model, of a road vehicle, means a class or family of road vehicles:
(a) of the same make; and
(b) of the same general type or appearance;
that includes the road vehicle.
CIRCULAR 0-1-2: A GUIDE TO THE CERTIFICATION OF NEW VEHICLES – TYPE APPROVAL
Types usually comprise a specific make and model (e.g. the Toyota Camry). In some cases, vehicle types can include known combinations or “variants”.
The definition allows for some flexibility
Common practice of many manufacturers is to collect all powertrain variants of 1 body variant into 1 application
