Immunity Test
Performance criteria
The performance criteria are based on the general criteria of the standard and derived from the product
specification
The performance criteria are based on the general criteria of the standard and derived from the product
specification
<or>
Criterion A: Continue to operate as intended during the test. No change of actual operating state, for
example change of channel is allowed as a result of the application of the test. Evaluation is carried out
for audio and video functions.
Evaluation of audio quality:
Unless otherwise specified in this standard, the criterion of compliance with the requirement is a
wanted to unwanted audio signal ratio of >=40dB at a wanted audio signal level of 50mW.
For AM sound receivers the criterion is >=26dB at 50mW.
The criterion for the audio part of TV receivers is >=40dB.
For AM and FM car radios, the criterion is >=26dB at 500mW.
Evaluation of picture quality
The criterion of compliance with the requirement is just perceptible degradation by observation of the
picture, the screen shall be observed under normal viewing conditions(brightness 15~20 Lux), at a
viewing distance of six times the height of the screen.
In the case of video tape equipment the test criteria relate to the picture, assessed on a test-TV-set,
which is connected to the video output terminal of the equipment.
Criterion B: Continue to operate as intended after the test .No degradation of performance or loss of
function. During the test degradation of performance is allowed, however no change of actual operating
state or stored date.
Criterion C: Temporary loss of function is allowed, provided the function is self-recoverable or can be
restored by the operation of the controls.
