Preliminary remarks

Protection of workers from electromagnetic fields is specified in the European EMF Directive
2013/35/EU. This directive is implemented in national law in the European Economic Area (EEA).
Employers are obligated to design workplaces in such a way that workers are protected from
impermissibly strong electromagnetic fields. To this end, assessments and/or measurements
must be performed for workplaces.
General conditions for correct assessment or measurement
1. The laws for protection from electromagnetic fields in force in individual EU member states
can go beyond the minimum requirements of the EMF Directive 2013/35/EU and always take
precedence.
2. The ICNIRP 2010 limits for the workplace are the basis for the assessment.
3. The 100 μT (RMS) mentioned below for assessment of active implants comes from the
26th BlmSchV (German Federal Emission Protection Regulations).
According to Directive 2013/35/EU, 500 µT (RMS) at 50 Hz is applicable here.
4. Compliance with the limit values was checked for the following frequencies:
– Line frequency 47 ... 63 Hz (see system data)
– Pulse frequency, for example 4/8/16 kHz and multiples thereof, assessed up to a
5. The routing of power cables has a significant impact on the electromagnetic fields that occur.
