Measurements must be performed at a sufficient number of frequencies to identify resonances. Typical step sizes:

: The SE is calculated as the ratio (in decibels, dB) between the reference signal and the attenuated signal. A high-quality chamber often requires an SE of 100 dB or more . Importance in Industry

Before any measurement, the standard defines key terms:
