The European Committee for Standardisation Technical Committee 346 (CEN TC 346) is developing European Standards (ENs) for conservation. Four working groups are developing standards that impact on preventive conservation.

  • WG4: Protection of collections
  • WG6: Exhibition lighting of cultural heritage – Joint working group between TC 346 and TC 169
  • WG7: Specifying and measuring indoor/outdoor climate
  • WG8: Energy efficiency of historic buildings


Published Standards

  • EN 15757: Specifications for temperature and relative humidity to limit climate- induced mechanical damage in organic hygroscopic materials.
  • EN 15758: Procedures and instruments for measuring temperatures of the air and the surfaces of objects.
  • EN 15759-1: Indoor climate, Part 1: Guidelines for heating churches, chapels and other places of worship.
  • EN 16242: Procedures and instruments for measuring humidity in the air and moisture exchanges between air and cultural property.
