ČSN EN 15999-2

This document classifies properties of passive showcases of cultural heritage objects for better preservation. It applies to most uses of the showcase: showcases for so called permanent or temporary exhibitions, historical or modular showcases, showcases in uncontrolled ambient environment, etc. It specifies how the performance of the showcase for the safe and secure display - as derived from needs identified during the risk assessment approach described in EN 15999-1:2025 - can be technically assessed by using classified properties. Aspects of active showcases (those using electricity to directly condition their microclimates) and anoxic showcases (those containing inert atmospheres instead of air) are mentioned in this document, but their properties are not defined, nor classified.
