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。
ISO 10848-4:2017规定了实验室和现场测量的建筑物,其中至少一个构成被测结构的构件是a类构件(定义见ISO 10848-1)。
实验室测量用于量化实验室结构抑制侧翼传输的连接性能。现场测量用于表征现场性能,通常不可能充分抑制不必要的侧翼传输;
因此,当安装在特定建筑结构中时,结果主要代表该连接的性能。
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。
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.
