标准范围

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。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，或表示要求，或作为预测方法的输入数据，如ISO 12354-1和ISO 12354-2。然而，测量数量Dn、f、Ln、f和Lne0、f仅代表本文件所述试样尺寸的性能。ISO 10848-2:2017在ISO 10848-1:2017第4.5节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类构件，如吊顶、通道地板、不间断采光立面或浮动地板。从一个房间到另一个房间的传输可以通过测试元件和增压室（如果有）同时发生。对于根据本文件进行的测量，确定总的声音传输，不可能将这两种传输分开。

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 fa？ades 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.
