标准摘要
[中文适用范围]： 或几个建筑构件。 本文件规定了建筑物的实验室和现场测量，其中构成被测建筑的至少一个元素是 A 型元素（在 ISO 10848-1 中定义）。 实验室测量用于量化来自实验室结构的抑制侧向传输的结点的性能。 现场测量用于表征现场性能，通常不可能充分抑制不需要的侧向传输；因此，结果主要代表了安装在特定建筑结构中时该连接点的性能。 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 12354-1 和 ISO 12354-2）的输入数据。 [外文原描述]： ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components. ISO 10848-4:2017 specifies laboratory and field measurements of buildings where at least one of the elements that form the construction under test is a Type A element (defined in ISO 10848‑1). 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 are primarily representative of the performance of that junction when installed in that particular building structure. 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.
