In what range should the temperature and humidity of archives be generally controlled?

The countries where archives are kept have clear regulations, and certain storage conditions must be met, which is conducive to the long-term preservation of archives. For example, according to the requirements of the National Archives Bureau on the temperature and humidity of archives, the temperature is 14 ~ 24℃, and it does not exceed 24℃ in summer; The relative humidity is 45% ~ 60%, and it does not exceed 60% in summer. Within the specified range, the fluctuation range of temperature and humidity every day and night requires a temperature of 2℃ and a relative humidity of 5%.

The appropriate temperature and humidity standards for archives are: temperature: 14℃-24℃, and relative humidity is maintained at 45%-60%. The temperature and humidity monitoring system can monitor the temperature and humidity data of archives in real time, analyze the temperature and humidity change trend of archives through historical data, and automatically control the automatic operation of air conditioners, dehumidifiers, humidifiers and sterilizers through the control system. Ensure the temperature and humidity of the archives, and prevent bookworms from breeding due to high temperature and high humidity or paper brittleness from increasing due to low temperature and low humidity. Thereby prolonging the service life of the archives.
