Road vehicles — Exterior protection for passenger cars
This document specifies the requirements and test methods for exterior protection for passenger cars. This document applies to passenger cars. The aim is to provide protection at the front and rear of the vehicle, of certain mechanical elements and, above all, for lighting, signals, charging ports and sensors (arranged at the front and rear of the vehicle and including but not limited to those used for automatic driving system, e.g. LiDAR, radar, camera) in cases of collision at low speed. Exterior protection is assured by protective devices, which are elements located at the front and rear ends of vehicles and designed in such a way as to allow contacts and small shocks to occur without causing any serious damage.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and expressions
related to conformity assessment, as well as information about ISO's adherence to the World Trade
Organization (WTO) principles in the Technical Barriers to Trade (TBT), see www.iso.org/iso/foreword.html.
This document was prepared by Technical Committee ISO/TC 22, Road vehicles.
This second edition cancels and replaces the first edition (ISO 2958:1973), which has been technically
revised.
The main changes are as follows:
— added the definition of protective devices;
— modified the definition of the vehicle corner and added Figure 2;
— added requirements for front and rear protective devices and their covered structures;
— added requirements for cameras and sensors installed on the front and rear protective device.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www.iso.org/members.html.

Introduction
This document was developed to define a general test for exterior protection for passenger cars. This
document mainly revises ISO 2958:1973. With the advancement of technology, emerging components
such as sensors, radars and cameras have been equipped with front- and rear-end protection devices for
automobiles, which have caused significant changes in the car body structure and have put forward higher
technical requirements for the front- and rear-end protection devices. At present, the concept and structure
of the bumper device is significantly different to 1973. Therefore, this document extends the definition of
the bumper and related technical requirements.

Road vehicles — Exterior protection for passenger cars
1 Scope
This document specifies the requirements and test methods for exterior protection for passenger cars. This
document applies to passenger cars.
The aim is to provide protection at the front and rear of the vehicle, of certain mechanical elements and,
above all, for lighting, signals, charging ports and sensors (arranged at the front and rear of the vehicle and
including but not limited to those used for automatic driving system, e.g. LiDAR, radar, camera) in cases of
collision at low speed.
Exterior protection is assured by protective devices, which are elements located at the front and rear ends
of vehicles and designed in such a way as to allow contacts and small shocks to occur without causing any
serious damage.
