Frequency of electromagnetic field in which an object is present | Contact current ALs (Ic)[mA] |
---|---|
up to 2.5 kHz | 1.0 |
2.5 ≤ f < 100 kHz | 0.4 f |
100 ≤ f ≤ 10,000 kHz | 40 |
NOTES
1. “f” is the frequency expressed in kHz.
2. The ALs are root mean square values.
3. The ALs represent the maximum steady state current created during a continuous contact with an object in an electromagnetic field.
Potential indirect effect | Magnetic flux density ALs (B0)[mT] |
---|---|
Interference with active implanted medical devices | 0.5 |
Attraction and projectile risk in the fringe field of high field strength sources (> 100 mT) | 3 |
NOTE
The AL for interference with active implanted medical devices represents the maximum field value at any place where a worker may be working.
Frequency of electromagnetic field in which an object is present | Contact current ALs (Ic) [mA] |
---|---|
100 kHz ≤ f < 110 MHz | 40 |
NOTES
1. The AL is a root mean square value.
2. The AL represents the maximum steady state current created during a continuous contact with an object in an electromagnetic field.
