General Information
- Abstract
IEC 61000-4-19:2014 relates to the immunity requirements and test methods for electrical and electronic equipment to conducted, differential mode disturbances and signalling in the range 2 kHz up to 150 kHz at a.c. power ports. The object of this standard is to establish a common and reproducible basis for testing electrical and electronic equipment with the application of differential mode disturbances and signalling to a.c. power ports. This standard defines: - test waveforms; - range of test levels; - test equipment; - test setup; - test procedures; - and verification procedures. These tests are intended to demonstrate the immunity of electrical and electronic equipment operating at a mains supply voltage up to 280 V (from phase to neutral or phase to earth, if no neutral is used) and a frequency of 50 Hz or 60 Hz when subjected to conducted, differential mode disturbances such as those originating from power electronics and power line communication systems. The immunity to harmonics and interharmonics, including mains signalling, on a.c. power ports up to 2 kHz in differential mode is covered by IEC 61000-4-13. Emissions in the frequency range 2 kHz to 150 kHz often have both differential mode and common mode components. This standard provides immunity tests only for differential mode disturbances and signalling. It is recommended to perform common mode tests as well, which are covered by IEC 61000-4-16.

Overview
EN 61000-4-19:2014 (CLC / IEC 61000-4-19:2014) is an EMC standard that specifies immunity testing and measurement techniques for conducted, differential‑mode disturbances and signalling on a.c. power ports in the frequency range 2 kHz to 150 kHz. It defines a common, reproducible basis for testing electrical and electronic equipment powered from mains supplies up to 280 V (phase‑to‑neutral or phase‑to‑earth) at 50 Hz or 60 Hz, focusing on disturbances originating from power electronics and power‑line communication systems.
Key topics and technical requirements
The standard establishes detailed, testable requirements including:
- Test waveforms - prescribed profiles (e.g., CW pulses with pause, rectangularly modulated pulses) for both differential voltage and differential current tests.
- Range of test levels - frequency‑dependent amplitude tables for 2 kHz–150 kHz to determine immunity levels.
- Test equipment - characteristics and performance requirements for signal generators, coupling/decoupling networks (CDNs) and verification instruments.
- Test setup - recommended wiring, auxiliary equipment connections and laboratory reference conditions to ensure reproducibility.
- Test procedures - step‑by‑step execution, frequency stepping and modulation approaches for applying disturbances to a.c. power ports.
- Verification procedures - methods to verify generator performance and CDN damping characteristics; guidance on evaluating and reporting test results.
- Scope limits - covers differential‑mode only; common‑mode immunity tests are recommended separately (see IEC 61000‑4‑16). Immunity to harmonics/interharmonics up to 2 kHz is covered by IEC 61000‑4‑13.
Applications and practical use
EN 61000‑4‑19 is used to assess and demonstrate the immunity of products to conducted disturbances in the 2 kHz–150 kHz band. Typical applications include:
- Protection of consumer, industrial and utility equipment from interference caused by power electronics (inverters, drives) and power‑line communication (PLC) systems.
- EMC compliance testing of meters, household appliances, industrial controllers, and UPS/power systems whose mains connections can receive differential signalling.
- Development and verification activities in design, production and conformity assessment carried out by EMC engineers, test laboratories, manufacturers, and compliance officers.
Practical benefits: consistent test methodology, repeatable results across labs, and clearer pass/fail criteria for differential conduction immunity.
