Risks & Metrics
Evaluation & General Comments
RISK
Accelerated rate of chemical decay in all organic materials due to the
cumulative effects of temperature and humidity, with especially high risk for
fast decaying organic materials such as acidic paper, color photographs and
cellulosic plastics.
TWPI = 35
OK
Mechanical Damage
Physical damage to
hygroscopic materials
Generally OK, but sensitive or fast responding hygroscopic materials such as
paintings, rare books, vellum manuscripts or musical instruments will be at
elevated risk of physical damage due to fluctuations of humidity.
% DC = 0.98
% EMC min = 7.4
% EMC max = 10.9
Mold Risk
Mold growth in area or
on collection objects
GOOD
Minimal risk of mold growth.
MRF = 0
Metal Corrosion
Corrosion of metal
components or objects
RISK
Heightened risk of metal corrosion due to extended periods of high levels of
humidity.
