ISO 11799:2015

Overview

ISO 11799:2015 - Information and documentation: Document storage requirements for archive and library materials - defines characteristics for repositories used in the long‑term storage of archive and library collections. The standard covers siting, construction, renovation, installation and equipment for buildings and rooms that store mixed media (paper, parchment, photographic, audiovisual and digital carriers). It supports preservation, access and risk mitigation while recognizing that local building codes govern many detailed safety and construction requirements.

Key topics and technical requirements

• Scope and applicability: Applies to all archive and library materials in repositories; permits creation of separate controlled compartments for special media.
• Risk management: Site and building risk assessment (flooding, subsidence, earthquakes, fire, nearby hazardous installations, pests, theft/terrorism).
• Construction & security: Purpose‑built or self‑contained units; physical security against theft, vandalism, arson and terrorism; secure emergency exits; recommendation to avoid windows or fit secure glazing.
• Indoor climate stability: Design for stable temperature and relative humidity using building orientation, insulation, thermal inertia and moisture buffering; recommendation for neutral/positive air pressure to reduce ingress of dust and pollutants. (See Annex C for recommended climatic guidance.)
• Inner structure & loads: Compartmentalization for fire control; fire/water‑resistant separations; floor load calculations based on records, containers and shelving; engineered bracing to prevent shelving collapse.
• Services & building systems: Separation of utilities from repository spaces where possible; building management systems (BMS) in separate fire compartments.
• Fire prevention, detection & extinguishing: Prevent fires and resist external fire spread; automatic detection (smoke/combustion products) with central monitoring panels and manual call points; portable extinguishers and consideration of automatic gas‑ or water‑based systems with no additives (Annexes A & B).
• Storage environment & equipment: Guidance on illumination, humidity/temperature control, ventilation, air quality and furniture/equipment selection. Annex D gives guidance on air pollutants.
• Maintenance & post‑occupancy: Ongoing maintenance and post‑occupancy evaluation to ensure objectives are met.

Applications and users

ISO 11799:2015 is practical for:

• Archivists and librarians planning storage and preservation strategies
• Architects and building engineers designing repository facilities or converting buildings for archives/libraries
• Facilities managers and conservators specifying HVAC, shelving, fire and security systems
• Risk managers assessing site vulnerabilities and disaster preparedness

Use cases include design of new purpose‑built repositories, renovation of historic buildings for archival use, specification of climate control and fire protection systems, and operational maintenance plans for long‑term preservation.
