At ESL Labs, we deliver comprehensive EMI and EMC testing services to help manufacturers ensure their products meet international electromagnetic compatibility (EMC) and interference (EMI) standards. Our goal is to make compliance testing straightforward and reliable—so your innovations perform flawlessly in the real world.
Our state-of-the-art facility features a Frankonia semi-anechoic EMI chamber, designed to facilitate comprehensive testing for conducted emissions, conducted susceptibility, radiated emissions, radiated susceptibility, and pre-compliance testing for various applications.
What Are EMI and EMC Testing — and Why They Matter
EMI (Electromagnetic Interference) testing identifies unwanted electromagnetic emissions from a device that may disrupt nearby electronics.
EMC (Electromagnetic Compatibility) testing ensures your equipment can operate properly in the presence of such emissions. In short, EMI and EMC testing confirm your product won’t cause or suffer from interference in its environment – critical for certification, safety, and performance.
New ESL Labs Facility with EMI Chamber
With almost 40,000 sq. ft. of space, the new testing facility for ESL Labs provides room to accommodate this state-of-the-art EMI and EMC testing capability.
The EMI semi-anechoic chamber is 9.68 m (L) x 6.53 m (W) x 6.00 m (H) with a 2m diameter turntable and 2000 kg capacity. This advanced Frankonia EMI chamber means ESL Labs can perform MIL-STD-461G testing on a variety of product sizes. The EMI chamber is comprised of anechoic cones and ferrite tiles to absorb electromagnetic radiation and to prevent any reflections from the walls, ceiling, or floor, creating a perfectly isolated testing environment.
The large size of the ESL chamber allows for tremendous flexibility when making decisions on what kind of test instrumentation can be used. Common testing instrumentation includes EMI receivers, signal generators, high-power RF amplifier racks, low frequency test sets, and high bandwidth digital oscilloscopes.

Frequently Asked Questions About EMI and EMC Testing
EMI (Electromagnetic Interference) and EMC (Electromagnetic Compatibility) testing evaluate how electronic devices emit and respond to electromagnetic energy. These tests ensure your equipment operates safely without interfering with other devices or being affected by external interference.
The difference lies in the focus of each test:
- EMI testing measures how much electromagnetic noise your product emits.
- EMC testing ensures your product can function properly even when exposed to electromagnetic noise from its environment.
Both are essential for ensuring compliance, reliability, and product safety.
Compliance testing is required by regulatory agencies and industry standards to ensure products don’t cause interference or fail due to electromagnetic exposure. Meeting EMI and EMC testing standards prevents costly recalls, protects users, and ensures your product can be legally sold in domestic and international markets.
EMI and EMC compliance testing is crucial for aerospace, defence, automotive, telecommunications, marine, and medical industries – any field where electronic equipment must operate reliably in high-interference environments.
ESL Labs performs testing according to major global and military standards, including:
- MIL-STD-461G / 462D
- RTCA/DO-160G
- FCC Part 15B
- ICES-001, ICES-003
- EN 55011, EN 55032 (CISPR 11/32)
Our engineers help identify the correct standard for your product’s intended use and certification region.
Yes. We provide pre-compliance EMI and EMC testing services to identify potential design issues early, saving you time and cost during final certification. This approach helps refine product design before submitting to full regulatory testing.
Testing timelines depend on the complexity of your product and the required standards. A typical pre-compliance test can take a few days, while full compliance certification may take one to two weeks or beyond. ESL Labs provides a detailed testing schedule as part of each project plan.
