ISO 10848（所有部分）规定了一个或多个建筑构件侧面传输特性的测量方法。 ISO 10848-3:2017规定了当交叉口有重大影响时，B类构件（定义见ISO 10848-1）的实验室和现场测量。 实验室测量用于量化实验室结构抑制侧翼传输的连接性能。现场测量用于表征现场性能，通常不可能充分抑制不必要的侧翼传输； 因此，当安装在特定建筑结构中时，结果只能被视为该连接性能的代表。 ISO 10848-3:2017在ISO 10848-1:2017第4.5节中被称为框架文件的支撑部分，适用于按照ISO 10848-1的定义在结构上连接的B类元件。 测量的数量可用于比较不同的产品，或表示要求，或作为预测方法的输入数据，如ISO 12354-1和ISO 12354-2。 根据ISO 10848-1:2017第4节的规定选择要测量的相关数量。 5.建筑构件的性能可以表示为构件和交叉点（如Dn、f、ij和/或Ln、f、ij和/或Lne0、f、ij）组合的总量，也可以表示为交叉点的标准化方向平均速度水平差。Dn，f，ij，Ln，f，ij，Lne0，f，ij，取决于元件的实际尺寸。

ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components. ISO 10848-3:2017 specifies laboratory and field measurements of buildings for Type B elements (defined in ISO 10848？1) when the junction has a substantial influence. Laboratory measurements are used to quantify the performance of the junction with suppressed flanking transmission from the laboratory structure. Field measurements are used to characterize the in situ performance and it is not usually possible to suppress unwanted flanking transmission sufficiently; hence, the results can only be considered representative of the performance of that junction when installed in that particular building structure. ISO 10848-3:2017 is referred to in ISO 10848？1:2017, 4.5 as being a supporting part to the frame document and applies to Type B elements that are structurally connected as defined in ISO 10848？1. The measured quantities can be used to compare different products, or to express a requirement, or as input data for prediction methods, such as ISO 12354？1 and ISO 12354？2. The relevant quantity to be measured is selected according to ISO 10848？1:2017, 4.5. The performance of the building components is expressed either as an overall quantity for the combination of elements and junction (such as Dn,f,ij and/or Ln,f,ij and/or Lne0,f,ij) or as the normalized direction-average velocity level difference of a junction. Dn,f,ij, Ln,f,ij, Lne0,f,ij and depend on the actual dimensions of the elements.
