Industry 4.0, digital facility management, distributed systems, IoT – radio frequency band usage is constantly increasing. These demands are, for example, being met by allocating ever higher transmission frequencies.
Mobile radio standard 5G or technical building equipment such as WLAN already communicates well above the 2.7 Gigahertz limit specified for EMC interference immunity tests in the “product family standard” for alarm systems EN 50130-4.
Service portfolio
An adaptation of the harmonised standards taking into account higher test frequencies is expected; the generic standards EN IEC 61000-6-1/2 already include these.
Given the critical discrepancy between the currently valid test spectrum and the actual radio interferences, VdS adapts its service portfolio.
Minimal extra costs
"The standard specifications are being overtaken by reality, as usual, we assure manufacturers at an early stage," explains Frank Hunold, the Head of the EMC laboratories at VdS, adding “This is why we have already upgraded our absorber halls for testing with electromagnetic fields to 6 GHz. Our customers now can include this in ongoing test procedures at minimal extra costs, thus avoiding separate re-tests at a later stage.“
