IEEE 299 Shielding Testing for MRI, SCIF, and EMC Facilities

Don’t settle for testing that adds complexity and risk to your schedule. Shielding Integrity Services (SIS) delivers expert, fully accredited, independent IEEE 299 Shielding Testing based on decades of practical, hands-on experience—not just theory. We use state-of-the-art automated systems that maximize testing efficiency, ensuring fast turnaround of accurate data and quick troubleshooting for any required performance adjustments. Whether validating a compact 3-meter setup or a specialized 10-meter facility anywhere in the world, SIS delivers the precise, compliant results you need to confidently move your projects forward.

Scope & Diverse Test Environments

The core purpose of RF Shielding Effectiveness (RF) testing is assuring a standardized and complete shielding evaluation for specialized facilities across various industries. We can perform just about any type of shielding effectiveness test, in any environment, anywhere in the world, on any-sized chamber.

Test Environments Include:

• Anechoic Chambers
• Secure Facilities (e.g., SCIFs)
• MRI/Medical Suites
• Clean Rooms
• Aerospace Assembly Labs
• Automotive Test Chambers

Test Standards & Methodology

While a wide range of standards may be selected, our commitment is to meeting the uniform technical requirements of your specific project.

Primary Test Standards

• IEEE 299 (2006): Standard used for measuring the effectiveness of electromagnetic shielding enclosures.
• EN50147-1: European standard for the performance of anechoic chambers.
• NSA 94-106: Military standard often applied to secure facilities and high-security requirements.

Test Lifecycle Support

We provide shielding effectiveness evaluation across the entire facility lifecycle, ensuring continuous performance and quick corrective action where needed.

Our Lifecycle Services:

• New Chambers: We validate new chambers before absorber or interior finishes are installed.
• Re-validation: We re-validate existing chambers to confirm ongoing performance.
• Corrective Action: We are equipped to recommend and implement corrective actions based on re-validation results.

Specialized Testing

In addition to standard RF shielding testing, SIS performs specialized tests that validate structural integrity and performance in high-security environments.

Key Specialized Tests

• SELDs Testing: We perform Shielding Effectiveness Level Determination (SELDs) testing on welded enclosures to verify the structural integrity of the metal panels and seams.
