[Nhcoll-l] [EXTERNAL] New HVAC - its a world of possiblilites

[Bacharach, Joan]

Hello Katja;

Do take a look at the National Park Service *Museum Handbook*, Chapter 4:
Museum Collections Environment at
*https://www.nps.gov/museum/publications/MHI/chap4.pdf
<https://www.nps.gov/museum/publications/MHI/chap4.pdf>* -- in particular,
the following sections:

Section E. What is the recommended temperature range for general
collections
Section F: What is the recommended RH set point and fluctuation range for
general collections
                  What is seasonal drift?
                   What is the recommended RH range for sensitive materials.

There is useful information in other sections, such as monitoring,
analyzing and controlling temperature and RH.

Trust this is useful.
Joan
