EMC test
Radiated emissions according to CISPR 11 vs. CISPR 32 (DIN EN 55011 vs. DIN EN 55032)
According to DIN EN 60601-1-2, the radiated emissions of industrial, scientific and medical equipment must comply with the requirements of CISPR 11. However, this does not apply to multimedia equipment and is specified accordingly in the rest of the standard. Multimedia equipment is information technology equipment whose main function is to input, store, output, display, retrieve, transmit, process, switch, monitor data and/or telecommunication messages. Examples include computers (PCs and all-in-one computers), bedside terminals, computer peripherals such as monitors, telecommunications equipment, radio receivers, televisions, etc.. Point 7.1.3 of the above-mentioned standard explicitly states that this type of ME equipment, or equipment suitable for connection to ME equipment or ME systems, must comply with the requirements of CISPR 32. The test of radiated emissions according to CISPR 32 covers a higher frequency range and is therefore to be classified as higher quality. CISPR 11 measures the frequency range up to 1 GHz, whereas the CISPR 32 test covers the range up to 6 GHz. Due to the high clock rate of the components used in multimedia equipment, interference can occur in the frequency range up to 6 GHz, which would not be detected during a test according to CISPR 11. This electromagnetic interference can lead to impaired functionality, which can lead to malfunctions, especially in devices in the sensitive field of medical technology. For this reason, the devices in the CLINIO and OPERION series from Rein Medical GmbH are certified in accordance with the requirements of CISPR 32 and underline the high quality standards we set for ourselves and our products.
