1A - Degradation rates of paper at various temperatures
      and relative humidity values compared with an
      assumed rate of one at 21 Deg. C (70 F) at 50%

      and relative humidity values compared with an
      assumed rate of one at 21 De. C (70 F) at 50%
      relative humidity. The relative degradation rate
      scale is about one-twentieth that of Figure 1A

Gives guidelines for the environmental parameters that influence the deterioration of paper-based records housed in a storage repository. Specifically, it suggests minimum and/or maximum values for temperature, relative humidity, exposure to light, and the removal of gaseous and particulate contaminants. The report is designed so that the user may select specific limits for a particular storage condition or repository.
