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.

Introduction
This document is an intermediate specification, published prior to the development of a full International
Standard. This document prescribes the usage of the wireless power transfer technology to charge
electrically propelled road vehicles. Even if the technology itself is well known, the implementation in
a vehicle is new and demands to meet the very specific requirements of the automotive industry. The
main purpose of this document is to respond to the upcoming market needs starting with determination
of basic safety requirements and documentation for the first findings for vehicle usage.
This document will be transformed into an International Standard as soon as consolidated technical
experiences are available. When transferring this document into an IS, technical changes are possible
to adopt the document to the latest level of knowledge.
