本欧洲标准旨在通知和协助用户选择和使用最合适的方法，以获得木材和砖石（包括砖砌，石材，混凝土，石膏，砂浆等）中水分含量或含水量的可靠测量）在具体建设的文化遗产案中。 它提供了一个基本框架，对上述经历风化，病虫害袭击，盐迁移或其他变化的文化遗产材料进行这种测量。 它规定了四种绝对方法（即重量法，卡尔费休滴定法，共沸蒸馏法和电石法）;解释其特性，优缺点，并给出了将读数转换为同一单位的规范，以使用不同方法进行测量可比。 它规定了三种主要的相对方法（即与材料平衡的电阻，电容和相对湿度），指出了当在文化遗产领域使用时的特征和不确定性。 此外，它还提供了十个其他相关方法，其特征，利弊的信息概述。 它给出了各种方法的校准的规格。它也比较

This European Standard is aimed to inform and assist users in the choice and use of the most appropriate method to obtain reliable measurements of the moisture content, or water content, in wood and masonry (including brickwork, stonework, concrete, gypsum, mortars, etc.) in the specific case of the built cultural heritage. It provides a basic framework to take and interpret this kind of measurements on the above cultural heritage materials that have undergone weathering, pest attack, salt migration or other transformations over time. It specifies four absolute methods (i.e. gravimetric, Karl Fischer titration, azeotropic distillation and calcium carbide); explains their characteristics, pros and cons, and gives specifications for the transformation of readings into the same unit to make measurements taken with different methods comparable. It specifies the three principal relative methods (i.e. electrical resistance, capacitance, and relative humidity in equilibrium with the material), pointing out their characteristics and uncertainties when used in the field of cultural heritage. In addition, it provides an informative overview of ten other relative methods, their characteristics, pros and cons. It gives specifications for the calibration of the various methods. It also compares the above methods in relation to their accuracy, sampling requirement, sample size, laboratory or field use, and other problems encountered in the field of cultural heritage to prevent instrument misuse, reduce uncertainties and avoid reading misinterpretation.
