Overview of EMI EMC Standards ITU T K 21 ITU T K 44

These standards define the defensive “armor” for telecommunications equipment installed at customer premises. While distinct from typical EMC data-noise testing, ITU-T K.21 and K.44 focus on resistibility—ensuring hardware survival against high-energy threats.

  • ITU-T K.44: The foundational “How-To” guide establishing test circuits, waveform generation (1.2/50 µs), and setup methodologies.
  • ITU-T K.21: The “Product Standard” setting pass/fail voltage limits specifically for equipment used in homes and offices (CPE).
  • Core Objective: Verifying protection against lightning surges, power induction, and accidental power contact.
