21、 uncertainty data for the tested specimen, these data shall be used. For declaration in test reports of products or system data, two sided intervals shall be used. It is recommended to use k = 2. NOTE k = 2, two sided intervals correspond to a confidence level close to 95 %. EXAMPLE In the absence o

22、f uncertainty data for a product, the airborne sound insulation of this product will be designated as: Rw(C;Ctr) = 33(-2; -5) dB; Rw = (33,2 2,4) dB (k = 2,two-sided); Rw+C = (31,3 2,6) dB (k = 2,two-sided); Rw+Ctr = (28,3 3,0) dB (k = 2,two-sided). In the absence of uncertainty data for the class o

23、f specimen tested, the following statement should be added: WARNING Due to the absence of knowledge of the uncertainty data for the class of specimen tested, the confidence level may be lower.
