Conservation standards

A resource for standards in conservation

Although we are rarely aware of them, formal standards are everywhere in our lives, from electrical plugs to advertising.  They have been in use in the field of heritage for many years and are still evolving today.

For the last 11 years, under the auspices of the European Committee for Normalisation (CEN), conservators from many European countries, including the UK, have been compiling standards for the conservation of both moveable and immovable cultural heritage. Some of them concern the care, transport and exhibition of collections.

There are now around 25 such standards published by the British Standards Institution (BSI) with others in development including standards on the process of conservation (decision making, planning and implementation) and on commissioning conservation.

A number of CEN and other British standards along with related documents is listed in the table below.
