Organization: IEC
Publication Date: 1 August 1995
Status: inactive
Page Count: 22
scope:

Standard measurements use the A-weighted sound pressure level as a measured variable. In case of difficult measuring conditions, sound intensity measurements are advantageous. This application is described in annex B.

According to this standard, measurements on transformers are made under no-load. If a transformer has a very low no-load noise, the noise due to load current can also influence the sound level. Annex C specifies the measurement conditions for determination of the noise due to load current.
