Five New Blogs from Keith Armstrong

Five New Blogs from Keith Armstrong image #1

23 Jun 2025

Here’s a quick overview of Keith’s five new blogs:

Magnetic Field Immunity: Why IEC 61000-4-8 (and more) may be required even beyond mains frequency.

PQ Test Expansion: Why PQ tests like voltage dips, harmonics, and interharmonics are becoming necessary.

IEC 61000-4-14: Covers voltage fluctuations. Increasingly cited in product assessments.

IEC 61000-4-16: For conducted common-mode disturbances—often overlooked, now crucial.

IEC 61000-4-13: Interharmonics can create unexpected EMC failures. You might need to test for them.

These updates reflect the post-2016 landscape of the EMC Directive—where “relevant” no longer means “sufficient.” If you want to avoid costly shipment delays or customs issues in the EU or UK, it’s time to widen your compliance net.
