3 Terms, definitions and symbols
3.1 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminology databases for use in standardization at the following addresses:
— ISO Online browsing platform: available at https://www.iso.org/obp
— IEC Electropedia: available at https://www.electropedia.org/
3.1.1 Characteristic values
3.1.1.1
characteristic strength value
population 5-percentile value obtained from the results of tests with a duration of 300 s at an equilibrium
moisture content of the test pieces relating to a temperature of 20 °C and a relative humidity of 65 %
3.1.1.2
characteristic stiffness value
either the population 5-percentile or the mean value obtained of tests with a duration of 300 s at an
equilibrium moisture content of the test pieces relating to a temperature of 20 °C and a relative humidity
of 65 %
Note 1 to entry: The stiffness values given in the Tables are mean values as these are most commonly used in
design. A NOTE below each of the Tables explains how to calculate the 5-percentile value.
3.1.1.3
characteristic density
population 5-percentile value with mass and volume corresponding to equilibrium moisture content at a
temperature of 20 °C and a relative humidity of 65 %
3.1.2 Service classes
3.1.2.1
service class 1
class characterized by a moisture content in the materials corresponding to a temperature of 20 °C and
the relative humidity of the surrounding air exceeding 65 % only for a few weeks per year
[SOURCE: EN 1995-1-1:2004, 2.3.1.3]
3.1.2.2
service class 2
class characterized by a moisture content in the materials corresponding to a temperature of 20 °C and
the relative humidity of the surrounding air exceeding 85 % for only a few weeks per year
[SOURCE: EN 1995-1-1:2004, 2.3.1.3]
3.1.2.3
service class 3
climatic conditions leading to higher moisture contents than in service class 2
[SOURCE: EN 1995-1-1:2004, 2.3.1.3]
3.1.3
load duration class
class characterized by the effect of a constant load acting for a certain period of time in the life of the
structure
Note 1 to entry: For a variable action, the appropriate class is determined on the basis of an estimate of the
interaction between the typical variation of the load with time and the rheological properties of the materials.
Note 2 to entry: For strength and stiffness calculations, actions are assigned to one of the load-duration classes
given in Table 1.
