标准范围
ISO 13347-2:2004详细描述了测定风扇声功率级的混响室方法。它是在标准化实验室条件下使用的,并认识到现场测试会增加不确定性。这些试验程序不一定适合现场试验条件。声学系统效应目前是大量研究工作的主题。ISO 5136涵盖了管道内方法,ISO 10302适用于小型风机,应与ISO 13347-2:2004结合使用。
ISO 13347-2:2004 gives a detailed description of reverberant room methods for the determination of fan sound power levels. It is for use under standardized laboratory conditions and recognises that tests in situ are subject to increased uncertainty. These test procedures are not necessarily appropriate to site test conditions. Acoustic system effects are presently the subject of considerable research effort.ISO 5136, which covers the in-duct method, and ISO 10302 for small fans, should be used in conjunction with ISO 13347-2:2004.
