标准范围

ISO 10211:2007规定了用于数值计算的热桥三维和二维几何模型的规范:热流，以评估建筑物或其一部分的整体热损失；最低表面温度，以评估表面冷凝的风险。这些规范包括模型的几何边界和细分、热边界条件以及要使用的热值和关系。ISO 10211:2007基于以下假设:所有物理性质都与温度无关；建筑元件内没有热源。ISO 10211:2007也可用于推导线性和点热透射率以及表面温度因子。

ISO 10211:2007 sets out the specifications for a three-dimensional and a two-dimensional geometrical model of a thermal bridge for the numerical calculation of:

• heat flows, in order to assess the overall heat loss from a building or part of it;
• minimum surface temperatures, in order to assess the risk of surface condensation.

These specifications include the geometrical boundaries and subdivisions of the model, the thermal boundary conditions, and the thermal values and relationships to be used.ISO 10211:2007 is based upon the following assumptions:

• all physical properties are independent of temperature;
• there are no heat sources within the building element.

ISO 10211:2007 can also be used for the derivation of linear and point thermal transmittances and of surface temperature factors.
