标准摘要
[中文适用范围]： 或几个建筑构件。 本文件仅考虑实验室测量。 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。 然而，测得的量 Dn,f、Ln,f 和 Lne0,f 仅代表本文件中描述的测试样本尺寸的性能。 该文件在 ISO 10848-1:2017, 4.5 中被称为框架文件的支持部分。 它适用于 ISO 10848-1 中定义的 B 型元素，例如吊顶、活动地板、采光不间断的外墙或浮动地板。 从一个房间到另一个房间的传输可以通过测试元件和静压室（如果有）同时发生。 对于根据本文件进行的测量，确定了总声音传输，并且不可能将两种传输分开。 [外文原描述]： ISO 10848 (all parts) specifies measurement methods to characterize the flanking transmission of one or several building components. This document considers only laboratory measurements. 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. However, the measured quantities Dn,f, Ln,f and Lne0,f only represent the performance with the dimensions for the test specimens described in this document. ISO 10848-2:2017 is referred to in ISO 10848‑1:2017, 4.5 as being a supporting part of the frame document. It applies to Type B elements as defined in ISO 10848‑1, such as suspended ceilings, access floors, light uninterrupted façades or floating floors. The transmission from one room to another can occur simultaneously through the test element and via the plenum (if any). For measurements made according to this document, the total sound transmission is determined and it is not possible to separate the two kinds of transmission.
