This draft European Standard gives specifications and guidance for the location, construction or adaptation of any form of building, or spaces within an existing building, specifically intended for internal storage and use of all heritage collection types and formats (where use includes display or handling, etc.). Clauses relating to risks associated with security, environmental hazards, fire, water and pests apply to buildings as a whole and to any room in which collections may be held. This standard applies to buildings where collections are housed permanently and can be used as guidance for shorter-term display spaces where appropriate. Some of the clauses in this standard are applicable in protected historic buildings that contain collections. In these settings, the scope for any alterations or achievement of conditions suitable for collections may be limited by the historic character of the structure. This draft European Standard should be seen as supplementary to national or local building regulations and specifications.
