What is an acceptable damp reading?

Damp readings are essential for libraries to ensure the preservation of their valuable collections. An acceptable damp reading is typically between 30% and 60%. This range helps to protect books, documents, and other materials from damage caused by excessive moisture or dryness.

Excessive moisture can lead to mold, mildew, and other forms of deterioration. Dryness can cause paper to become brittle and degrade. By maintaining an optimal damp reading, libraries can help to preserve their collections for future generations.

Factors that Affect Damp Readings

  • Outside temperature and humidity
  • Building materials and insulation
  • Ventilation and air conditioning systems
  • Storage conditions

Libraries must carefully monitor these factors and make adjustments as necessary to ensure that damp readings remain within an acceptable range.

Monitoring Damp Readings

Damp readings can be monitored using a variety of instruments, such as:

  • Hygrometers
  • Psychrometers
  • Moisture meters

Libraries should establish a regular schedule for monitoring damp readings to ensure that they are within an acceptable range.

Conclusion

Damp readings are an important aspect of library preservation. By maintaining an optimal damp reading, libraries can help to protect their collections from damage caused by excessive moisture or dryness. Regular monitoring of damp readings is essential to ensure that they remain within an acceptable range.
