Temperature

---

 

• in discipline of chemistry, accepted maxim is that for every 10C increase in temperature, the rate of chemical reaction doubles. For paper, however, every 5C increase will double the rate of deterioration.

• The recommended temperature for a general collection that is paper dominant is between 18C and 20C (or 65 to 68F).  If  RH is controlled (40 to 45%), these temperature levels (in a general sense) will be to the benefit of all materials.

• Temperatures of over 25C (77 F) are considered unacceptable for any archival material.
