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

Introduction
Building information modelling (BIM) provides a digital technology for describing and displaying
information required in the planning, design, construction and operation of constructed facilities.
Increasingly this modelling approach is expanding to encompass all aspects of the built environment,
including civil infrastructure, utilities and public space.
The standard EN ISO 16757 defines the structure of a product catalogue model for data sharing and data
exchange of product models in catalogues. It contains the definitions for
— Selection of products from different product classes and product variants
— Combining product components and accessory to products
— Geometrical representation in technical systems
— Connectivity to other products in models of technical systems
— Calculation of dynamic property values according to the product behaviour in technical systems
The standard EN ISO 16757 consists of the following standards:
— EN ISO 16757-1:2015 Data structures for electronic building services product catalogues - Concepts,
architecture and model
This standard describes the fundamental concepts and assumptions about the creation of manufacturer-
related product catalogues as BIM data exchange models. It describes the content of catalogues and the
mapping of the content to a data format.
This data format delivers the opportunity to search and select product data together with accessory
data which can be read in into software applications for planning, designing, calculating and simulating
as well as for facility managing.
— EN ISO 16757-2:2017 Data structures for electronic building services product catalogues – Geometry
This standard describes the concept of geometry of the Building Services product data of a catalogue in
form of 2D symbols and 3D shape models and specifies the required spaces and ports.
It contains the fundamental concepts and assumptions about the parametric geometry of special
products, used in planning software applications e.g. for air condition systems such as ducts and
transitions between different forms. Also it contains a concept for representing products as 3D solid
models, which are made from thin sheet metal.

Dictionary structures for product catalogue
1 Scope
ISO 12006-3 defines the underlying data model for BIM related dictionaries. This will be the foundation of
this standard.
Engineering tools are used to define, simulate and operate building services systems (including e.g. HVAC
systems and building automation systems). To build such a system basically means to interconnect different
products in a way that the resulting system fits into the building and works according to the functional
requirements. The products are selected from product catalogues of manufactures or distributors.
Important aspects of these products are information on their behaviour in different situations and the
connection points that allow to connect the products and to build the system.
The goal of this st
