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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11452-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3,
Electrical and electronic equipment.
This second edition cancels and replaces the first edition (ISO 11452-2:1995), which has been technically
revised.
ISO 11452 consists of the following parts, under the general title Road vehicles — Component test methods
for electrical disturbances from narrowband radiated electromagnetic energy:
Part 1: General principles and terminology
Part 2: Absorber-lined shielded enclosure
Part 3: Transverse electromagnetic mode (TEM) cell
Part 4: Bulk current injection (BCI)
Part 5: Stripline
Part 7: Direct radio frequency (RF) power injection
The radiating loop method is to form the subject of a future part 8.

Introduction
Immunity measurements of complete vehicles are generally able to be carried out only by the vehicle
manufacturer, owing to, for example, high costs of an absorber-lined shielded enclosures, the desire to
preserve the secrecy of prototypes or a large number of different vehicles models.
For research, development and quality control, a laboratory measuring method can be used by both vehicle
manufacturers and equipment suppliers to test electronic components.
