BS EN 50421 is a European standard on standalone broadcast transmitters that discusses the product standard to demonstrate the compliance of stand-alone broadcast transmitters to ensure protection against EMF hazards.
BS EN 50421 applies to fixed stand-alone broadcast transmitters operating in the frequency range 30 MHz to 40 GHz when put on the market. The term broadcast transmitter covers fixed stand-alone broadcast transmitters intended for use with external antennas of the same or another manufacturer.
The object of BS EN 50421 is to demonstrate the compliance of such equipment with the reference levels, or the basic restrictions related to public exposure to radiofrequency electromagnetic fields.
BS EN 50421 on the standard to demonstrate the compliance of stand-alone broadcast transmitters is useful for:
An electromagnetic field (EMF) is an area of moving electrical charges. Some EMFs, especially those involving ionizing radiation, can be harmful. For most people, exposure to EMFs occurs daily, as the fields are virtually everywhere.
BS EN 50421 provides you with guidance on the conditions for calculation and measurement, limits, evaluation of results and determination of compliance, the documentation provided by the equipment manufacturer, etc.
The product standard provided by BS EN 50421 assists you to demonstrate the compliance of stand-alone broadcast transmitters and understand the basic restrictions related to public human exposure to radiofrequency electromagnetic fields, enhancing safety, improving human working conditions, and counteracting adverse effects on human health and performance.
With obedience and compliance to BS EN 50421, you can enhance stand-alone broadcast transmitter effectiveness and efficacy and manufacture a standardized high-quality product and improve the quality of life
