Categorization and classification of civil unmanned aircraft systems
This document specifies requirements for the classification and grading of civil unmanned aircraft system (UAS). This document applies to heavier than air aircraft as well as lighter than air aircraft of any possible architecture. This document applies to the industrial conception, development, design, production and delivery of civil UAS. It also applies to modification, repair and maintenance of civil UAS. The characteristics in this document can be used individually or in combination, to meet specific needs of the classification and grading of civil UAS. Risk-based categorization of UAS operations is prerogative of the aviation authorities and it is hence out of scope of this document.

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 documents 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).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).

Introduction
This document sets out a methodology for the multi-dimensional classification of unmanned aircraft
system (UAS). The purpose of this classification model is not to replace any existing regulatory model
but to provide a more granular classification tool for use by those who need to approach the classification
of UAS from their own perspective and for whom the regulatory model is too broad. Examples may
be but are not limited to; engineers, manufacturers, certification bodies, insurance underwriters or
accident investigators.
