4.2.1 The limits for discontinuous disturbance depend mainly on the character of the disturbance and on the click rate N as given in detail in 4.2.2 and 4.2.3.
No discontinuous disturbance limits apply in the frequency range 30 MHz to 1 000 MHz.
NOTE The level of disturbances below 30 MHz is interpreted as an indication for the level above 30 MHz.
4.2.2 Frequency range 148,5 kHz to 30 MHz (terminal voltages)
4.2.2.1 The limits of Table 1 apply also to discontinuous disturbances from all equipment which produce:
a) disturbances other than clicks, or
b) clicks with a click rate N equal to or greater than 30.
Appliances as described in 4.2.3 are exempted.
NOTE Examples of discontinuous disturbances for which the limits for continuous disturbance apply are shown in
Figures 4a and 4b.
4.2.2.2 For discontinuous disturbance, the click limit Lq is attained by increasing the relevant limit L (as given in 4.1.1) with:
44 dB for N < 0,2, or
20 lg (30/N) dB for 0,2 ≤ N < 30
NOTE Examples of discontinuous disturbances which are classified as clicks are shown in Figures 3a, 3b and 3c.
