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 |
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 |
The AL for interference with active implanted medical devices represents the maximum field value at any place where an employee may be working.
Frequency of electromagnetic field in which an object is present | Contact current ALs (IC) [mA] |
---|---|
100 kHz ≤ f < 110 MHz | 40 |
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.
