[中文适用范围]： 或几个建筑构件。 本文件规定了 B 类元件的建筑物的实验室和现场测量（定义实验室测量用于量化实验室结构抑制侧向传输的结点的性能。 现场测量用于表征现场性能，通常不可以充分抑制不需要的侧向传输；因此，结果只能被视为代表安装在特定建筑结构中时该连接处的性能。 该文件在 ISO 10848-1:2017, 4.5 中被称为支撑部件到框架文件并适用于按照 ISO 10848-1 定义在结构上连接的 B 型元素。 测量的数量可用于比较不同的产品，或表达要求，或作为预测方法（例如 ISO）的输入数据12354-1和ISO 12354-2。 根据ISO 10848-1:2017, 4.5选择相关测量量。 建筑构件的性能可以表示为元素和连接点组合的总量（例如 Dn,f,ij 和/或 Ln,f,ij 和/或 Lne0,f,ij），也可以表示为归一化方向- 路口的平均速度水平差 D v, ij , n。 Dn,f,ij、Ln,f,ij、Lne0,f,ij 和 D v, ij , n 取决于元件的实际尺寸。 [外文原描述]： 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.
