We have been working on a 'Practical light policy' for some time
(see ICOM-CC 12th Triennial Meeting, Lyon, 1999, Derbyshire, A. and
Ashley-Smith, Jonathan. 'A Proposed Practical Light Policy for works
of art on paper at the V&A' pp38-41). We are currently updating this

In this policy we suggest simplifying categorisation of objects as
Sensitive (ISO 1-4) or Durable(ISO 5-8). The idea is to allow easy
and rapid categorisation without the need for analysis to determine
which pigments are present etc.

Sensitive category objects are then allowed on display at 50 lux for
20% of the time. e.g. 1 year in 5 or 2 years in 10 before rotation.
Durable category objects can be on permanent display at 200 lux
without rotation. These figures are based on giving an object 'a
life' of some 500 years. They also require a suggested rotation only
every 2 years in order to reduce the burden on
curators/conservators/exhibition staff.
