DIN EN 15758:2010-12 EN 15758:2010 (E) 4 Introduction This standard is intended to assist in providing an acceptable environment for tangible cultural heritage. The te
19、mperature of the air and of object surfaces constitute important aspects of that environment. Temperature is one of the factors which can have a profound effect on the preservation of objects. Physical characteristics of materials change as they absorb or release heat. Objects expand and contract as
20、 the temperature changes, become rigid and brittle if the temperature falls below the glass transition temperature, or are mechanically damaged by the melting and freezing of water. The rates of some important chemical reactions, such as the degradation of cellulose (paper, textiles) increase with r
21、ising temperature. Temperature influences the activity of fungi and insects responsible for the bio-deterioration of organic materials. Temperature may affect some minerals and masonry crystallisation. Temperature also has an important indirect effect: a rise in temperature causes lowering of the re
22、lative humidity, which results in the drying of moisture absorbing materials such as wood, paper or leather. Such drying may lead to shrinkage and embrittlement. When direct radiation from sun, lamps or radiant heaters reaches objects, the consequent temperature rise causes drying even when the rela
23、tive humidity of the surrounding air remains constant. Whatever the air temperature, the water vapour may condense on cold surfaces if their temperature drops below the dew point. The control of levels and variability of temperature contributes to a proper environment for cultural property and there
24、by reduces the risk of deterioration. Such control is an important preventive measure which will minimise the need for future conservation interventions. This standard recommends procedures for measuring the temperature of the air and of the surfaces of cultural property in indoor and outdoor enviro
