BS EN ISO 10848-2:2017规定了测量方法，以表征一个传感器的侧面传输特性 或者几个建筑构件。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 作为预测方法的输入数据，如ISO 12354-1和ISO 12354-2。然而，这一点是可以衡量的 数量Dn、f、Ln、f和Lne0、f仅代表试样尺寸的性能 本文对此进行了描述。本文件在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、， 照明不间断的正面或浮动地板。 可能会发生从一个房间到另一个房间的传输 同时通过测试元件和增压室（如有）。根据 在本文件中，确定了总的声音传输，不可能将两者分开 各种传播方式。交叉引用:ISO 354:2003（R05）Ed 2ISO 10848-1:2017ISO 717-2:2013 ED3ISO 717-1:2013 ED3ISO 12999-1:2014ISO 12354-1:2017ISO 15186-1:2000ISO 12354-2:2017ISO 10140-2:2010ISO 10140-3:2010购买本文件时提供的所有当前修订版均包括在内。

BS EN ISO 10848-2:2017 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.This document 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 facades 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.Cross References:ISO 354:2003 (R05) Ed 2ISO 10848-1:2017ISO 717-2:2013 ED3ISO 717-1:2013 ED3ISO 12999-1:2014ISO 12354-1:2017ISO 15186-1:2000ISO 12354-2:2017ISO 10140-2:2010ISO 10140-3:2010All current amendments available at time of purchase are included with the purchase of this document.
