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.

Introduction
The use of the EQuipment eXchange (EQX) data format simplifies exchange of data related to operation and
calibration of equipment and channel groups, such as transducers and anthropomorphic test devices (ATDs).
An extended option is to transport additional metadata information like test number and test types between
different laboratories and to calibration service providers to deliver an easy option to automatically fulfil
customer specific naming rules and metadata definitions.
The purpose of this document is to help users save time and prevent errors by not having to manually input
data in different systems when:
— exchanging calibration information between customer and calibration service provider;
— exchanging equipment between test laboratories;
— exchanging test meta data information between laboratories.
