Archives constant temperature and humidity machine - the ideal "housekeeper" of the collection of materials
The archive is a place where important archive materials are kept. Too high or too low temperature and humidity in the archive will affect the durability of the archive materials.
Therefore, as early as 1923, archival scholars have proposed that the environment of high temperature and humidity is one of the important threats to the maintenance of archives. The Society of Archivists has also emphasised many times in academic forums that the regulation of temperature and humidity in archival repositories has a great deal to do with the protection of archives and the extension of their lifespan.
Temperature and humidity requirements for archive repositories in China
The Temporary Provisions on Temperature and Humidity Management in Archives is a control method on temperature and humidity management in national archives issued by the State Archives Administration in 1985 circular, which is applicable to comprehensive archives and repositories at all levels. System and professional archives, in addition to the requirements of the profession, should refer to the implementation. Among them, the temperature and humidity requirements of the archives repository for the archives temperature 14 ~ 24 ℃, relative humidity 45% ~ 60% RH; heating library temperature is not less than 14 ℃, relative humidity is not less than 45%; summer temperature is not greater than 24 ℃, relative humidity is not greater than 60%. Fluctuations per day and night, the temperature does not exceed ± 2 ℃; relative humidity does not exceed ± 5%.
The development of this standard requirement is in the comprehensive consideration of China's national economic conditions and climatic conditions, as far as possible to facilitate the preservation of materials made of archives and limit the growth and reproduction of archival moulds and fungi under the environmental requirements of the development.
