Over deze norm
|Commissie||Klimaatbeheersing in gebouwen|
Gives the principles and criteria to be complied with for the determination of the laboratory steady-state heat transfer properties of masonry walls in a hot box by means of a heat flow meter mounted on one face of the masonry wall to be tested (i.e. the test specimen). It describes the apparatus, measurement technique and necessay data reporting. The property that is measured is the surface-to-surface thermal resistance of the specimen, provided that the homogenity criteria of 6.1.1 are met. From these measurements the thermal transmittance of a masonry wall can then be calculated from this value with standardized surface coefficients. Provides for measurements on both dry and moist specimens, provided that the conditions indicated in 5.2.3 are met. The influence of moisture content on the thermal properties of masonry can be taken into account by measurements at different moisture contents of the specimen in the range of the practical moisture content including the dry state, which corresponds to the most frequent testing condition. The method is suitable for specimens in a vertical position (walls) and in a horizontal position (ceilings and floors).
