Foreword
This document (prEN 15999:2009) has been prepared by Technical Committee CEN/TC 346 “Conservation of
cultural heritage”, the secretariat of which is held by UNI.
This document is currently submitted to the CEN Enquiry.
Introduction
Better material knowledge of objects and their interaction with the environment, results in better preservation.
With increasing development of mass cultural tourism the number of exhibitions and visitors are likely to
continue to expand in the future.
In light of this new knowledge, and to prevent risks of decay related to the exhibitions, the showcase is a
useful tool to preserve and protect objects.
In a showcase, environmental parameters such as hygrometry, dust, pollutants, and risks of physical damage
such as theft, and vandalism can be better controlled.
This document concerns all those in charge of the preservation and the exhibition of cultural heritage objects
or in charge of designing, making or fitting out showcases.
1 Scope
This document defines the characteristics and the conditions for use of showcases for the exhibition of cultural
heritage, reducing environmental interaction, and complying with the requirements for better preservation.
2 Normative references
Not applicable.
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
absorption
physical/chemical process that occurs when a gas or liquid solute diffuses into a solid to form a solution or is
transported and kept into the volume by capillary forces
3.2
accessibility
physical capability of intervention in a display case: handling of an object, technical intervention, and
maintenance
3.3
buffers
material which resists change of relative humidity, acidity, or temperature, by adsorbing/adsorbing or

space distributions) of the atmospheric variables (e.g. temperature, humidity, radiation, air motions) including
heat and mass exchanges with other bodies (e.g. infrared emission, lighting, evaporation/condensation,
particulate deposition) over a period of time representative of all the conditions determined by natural and
manmade forcing factors
3.7

4 Principles and components of a showcase for exhibition of objects
4.1 Functions of the showcase
The fundamental functions of a showcase are:
- to display an object while protecting it,
- to prevent and minimize any kind of adverse effects to the objects,
- to reduce the exchange rate of air and associated components such as water vapour, dust, and pollutants,
between the internal volume and the outside environment,
- to improve object preservation, safety and security.
4.2 Criteria of design or choice of the showcase
The design, the adaptation or the choice of a showcase shall be determined by the aim of showing an object
in conditions of safety and security, and at the same time providing the best conditions needed for the object
preservation. It shall conform to standards or regulations of public institutions.
It is necessary to take into account:
a) the characteristics of the object:
- dimensions (height, width, depth) and weight,
- physical, chemical, and structural nature of the exposed materials,
- brittleness and sensitivity in relation to the material history of the object;
b) the collection management of the institution: turnover of the collections, exhibition duration, handling of the
objects and of the showcase;
c) the maintenance and interior cleaning of the showcase: they shall be easy and without danger for the
objects;
e) the showcase and the public: stability, sufficient space of circulation, lighting;
f) environmental characteristics of the area where the showcase will be located.
d) placement of the object in the exhibition.
4.3 Components of the showcase
The showcase is composed of:
- an exhibition volume for the objects,
- technical compartments with devices to control lighting, microclimate, pollutants and biological deterioration;
- supports;
- a base to ensure static stability.
4.3.1 Exhibition volume
The exhibition volume contains and presents the objects.
It shall be made with stable, inert and neutral materials.
Its dimensions take into account the size of the objects, their condition, props, supports and mountings, the
accessibility and any element of the museographical context.
The contact between the leaf and the frame ensures the permanent sealing of the interior volume. A leaf
allowing access to at least 80% of this volume shall facilitate the handling of the objects or any operations.
It allows the installation of sensors/devices to monitor or control the internal environmental factors and
facilitates the registration of data.
4.3.2 Technical compartments
The technical compartments have their own access allowing for the maintenance of the installations.
The technical compartment dedicated to the regulation of the microclimate of the showcase is related to the
exhibition volume. The air circulation between the technical compartment and the exhibition volume allows a
fast and homogeneous air exchange.
The sealing of the opening is the same as for the exhibition volume.
The technical compartment dedicated to the light sources is isolated from the exhibition volume. It has its own
ventilation if necessary, with the possibility of controlling the temperature and humidity, while avoiding air
leakage, light escape and dust contamination.
The technical compartments of the showcase shall be stable and damp vibrations.
4.3.3 Base and attachment unit of the showcase
The base or any attachment unit of the showcase shall ensure its stability and limit the vibrations.
The base shall be conveniently large to guarantee the stability and balance of the exhibition volume. In the
event of fixing of the showcase, the system shall take into account the weight of the showcase and its
contents, and the quality of the surface of fixing.
4.3.4 Device of presentation of the collections
4.3.4.1 Overlay inside the showcase
