Standards and Regulations

limit will be extended further down to a new lower limit of 9 kHz. The new regulations will impact signifi cantly on a wide range of industry sectors including e-mobility, energy management, machinery, building technology, medical devices and robotics. The overarching objective of this extension to current frequency limits is to ensure that all devices can co-exist harmoniously with little or no risk of interference between them.
The immediate concern for hardware vendors, however, is that this extension of current standards will impose signifi cant constraints on the specifi cation, design, and manufacture of new products. As well as adding to product development lifecycles, there is a real worry that these changes will increase the cost of new products coming onto the market. And in today’s ultra- competitive marketplace, that’s an additional burden that few manufacturers will relish. The development cycle for a typical electronic or electromechanical product may easily stretch over a couple of years, or even longer. And this means that the clock is already ticking for manufacturers to take account of these regulatory changes, ahead of 2026 when they take effect. To ensure compliance, products that are already available on the market might require adapted fi lters with higher bandwidth performance in the next generation. For new products that are either planned or currently in development, meanwhile, manufacturers must ensure that the design is adapted to ensure compliance. In both cases this will be achieved with the integration of suitable fi ltering technology, depending on the product and its application. What’s more, it requires manufacturers to have access to testing equipment and facilities suitable for lower frequencies that they may not already have.

The impact of these revised regulations is already having signifi cant impact on the EMC landscape. Some large companies have already started to take the new standards into account in their new developments. And from a vendor’s perspective, the best way to navigate these changes successfully is with the help of an experienced partner. At Schaffner we’ve been at the forefront of developing innovative electromagnetic interference solutions for six decades. In parallel with our fi lters, chokes and other EMC/EMI products, we’re a trusted source of advice and guidance to other vendors on designing and testing their products to ensure they’re compliant with all relevant standards. By carefully evaluating the design of new equipment and systems, we can take away the risk and uncertainty around creating a new product, while also helping minimise the burden of additional development time and associated costs.

Schaffner’s own recent research has confi rmed widespread uncertainty around industry’s readiness for these upcoming changes. While the vast majority (almost 90 per cent) of respondents across a range of sectors believe that the extended regulations will impact on their business, there is far less confi dence about its actual effect on new design projects, and what concrete actions need to be taken now. As well as revealing that only half of respondents had access to adequate facilities for testing down to 9 kHz, the survey also confi rmed that the majority of vendors (86 per cent) are currently reliant on passive fi ltering techniques. These applications can often be better served by the latest generation of active solutions that will offer improved fi ltering performance down to 9 kHz as well as potentially smaller physical dimensions.
