The "GB/T 44420-2024 Rapid Determination of Moisture Content of Bamboo and Wood Artifacts in Collections" standard provides a simple and rapid method for determining the moisture content of bamboo and wood artifacts in collections. The standard is applicable to bamboo and wood artifacts whose moisture content has reached the equilibrate with the preservation environment after drying treatment. The principle of capacitance method is used for measurement. By measuring the change of capacitance dielectric constant of materials, the moisture content of bamboo and wood artifacts is indirectly deduced, so as to effectively monitor the preservation status of cultural relics and prevent damage caused by high or low moisture content. This standard provides important technical support for museums, libraries and other collection units to ensure the long-term protection and maintenance of bamboo and wood artifacts.
