Certification Standards

TFRi certification exists because the MIT study demonstrated that improper design doesn’t just fail to protect — it amplifies. The difference between engineered shielding and improvised foil is the difference between a Faraday cage and an antenna.

The Four Standards

Every product bearing the TFRi certification mark has been evaluated against four independent standards. Failure on any single standard disqualifies the product from certification. There is no partial certification. A product either meets all four thresholds or it does not carry our mark.

TFRi-SA.01

Signal Attenuation

Measures the product’s ability to reduce electromagnetic signal strength across the functional frequency range. Testing is conducted in a controlled anechoic environment using calibrated signal generators and spectrum analyzers.

The frequency range of 100MHz to 10GHz covers AM/FM radio, cellular communications (2G through 5G), WiFi (2.4 GHz and 5 GHz bands), Bluetooth, satellite communications, and the majority of government-allocated frequency bands identified in the MIT study.

Minimum threshold: 20dB attenuation across 100MHz–10GHz

TFRi-RA.01

Resonance Avoidance

The most critical standard. The MIT study identified that improperly designed shielding can create resonance patterns that amplify signals rather than attenuate them — specifically at 1.2 GHz and 2.6 GHz, which are allocated to US government use.

TFRi-RA.01 tests for amplification at all frequencies within the functional range, with particular attention to the bands identified in the MIT findings. Any measured amplification — even marginal — results in automatic disqualification.

Threshold: Zero amplification at any tested frequency. No exceptions.

TFRi-MI.01

Material Integrity

Shielding performance must be sustained over the product’s expected use life. TFRi-MI.01 subjects products to accelerated wear simulation equivalent to 500+ hours of standard daily use, including exposure to moisture, body heat, mechanical stress from folding/unfolding, and UV exposure.

Post-testing, the product must still meet TFRi-SA.01 attenuation thresholds. Performance degradation of more than 15% from baseline measurements results in disqualification.

Threshold: ≤15% attenuation degradation after 500+ hours simulated wear

TFRi-WB.01

Wearability Baseline

Cognitive protection that is not worn provides no protection. TFRi-WB.01 evaluates whether a product can be worn in standard public environments without drawing undue attention to the shielding mechanism — because a product that signals “I am wearing electromagnetic shielding” to every observer defeats the purpose of discrete cognitive defense.

This standard is evaluated qualitatively by a panel of independent reviewers in controlled social environments. Products that consistently prompt unsolicited questions about their purpose are flagged for redesign.

Threshold: Qualitative panel assessment — product must be suitable for sustained public wear

Certification Process

Application

Manufacturers submit a certification request with product specifications, material composition, design documentation, and three production samples. Application fee covers testing costs and is non-refundable regardless of outcome. We are transparent about this because transparency about money is one of the few things we can verify.

Laboratory Testing

Products are tested against all four standards in sequence. TFRi-RA.01 (Resonance Avoidance) is tested first, as failure is immediate grounds for disqualification and saves the applicant the cost of further testing. We consider this a courtesy.

Results & Reporting

Full test results are provided to the manufacturer regardless of outcome. For products that fail, specific failure points are documented so the manufacturer can address design deficiencies and reapply. We want products to pass. That is the point of having standards.

Certification & Mark License

Products meeting all four standards receive TFRi certification and a license to display the TFRi certification mark. Certification is valid for 24 months and must be renewed with retesting. Material or design changes during the certification period require immediate retesting.

Use of the TFRi Mark

The TFRi certification mark is a licensed mark. Unauthorized use constitutes fraud — a claim we make with full awareness of the irony of a tinfoil hat research institute invoking legal frameworks. Authorized use requires:

Products: The mark must appear on the product itself (garment tag or direct print), the product packaging, and any point-of-sale materials. The simplified stamp mark is approved for garment tags at sizes down to 1cm. The full seal is required for packaging and certificates of authenticity.

Digital: The mark may be displayed on product pages for certified products only. It must not appear on pages displaying uncertified products, as this implies certification by association. We have had this conversation with manufacturers before.

Modification: The mark may not be modified, recolored, distorted, or partially displayed. It may be rendered in black on white, white on black, or navy on white. No other color combinations are authorized.

Verify a Product

Every TFRi-certified product carries a unique certification number on its tag or packaging. Enter this number below to verify that the product has been tested and currently holds valid certification.

If a product displays the TFRi mark but does not have a verifiable certification number, please report it to compliance@tinfoilresearch.com. We take unauthorized use of our mark seriously, which is a sentence we never expected to type when we founded an institute dedicated to the study of protective headwear.
