What is an fcc test laboratory?

An fcc test Laboratory is a third-party organization accredited by the U.S. Federal Communications Commission (FCC) responsible for verifying the electromagnetic compatibility (EMC) of electronic products. The laboratory must be equipped with facilities such as shielded rooms, spectrum analyzers, and antenna towers, and must pass evaluations by accreditation bodies such as A2LA.

JJR Laboratory is equipped with Full-Anechoic Chambers (FAC) and Semi-Anechoic Chambers (SAC), covering a testing range from 9kHz to 40GHz, providing one-stop services for wireless products from pre-testing to formal certification.

Why is fcc certification required?

Product Type	Applicable Regulation	Mandatory
WiFi/Bluetooth Devices	fcc part 15	Yes
Mobile Phones/Communication Terminals	FCC Part 22/24/27	Yes
Industrial/Scientific/Medical (ISM) Equipment	fcc part 18	Yes
Household Appliances/IT Equipment	FCC Part 15 Subpart B	Yes

Two Major Types of FCC Certification

Effective November 2, 2017, the FCC merged the original DoC and Verification procedures into sdoc. The current system is divided into two categories:

Certification Type	Applicable Products	Test Content	Issuance Method
fcc sdoc	Standard electronics without wireless functions	EMC (Electromagnetic Compatibility)	Manufacturer's self-declaration; no direct fcc approval required
fcc id	Products with wireless transmission (Bluetooth, WiFi, etc.)	EMC + RF (Radio Frequency)	Reviewed by a TCB (Telecommunication Certification Body); unique FCC ID issued

Note: Some e-commerce platforms may require both the FCC ID certificate and the SDoC report for wireless products.

JJR Laboratory can complete SDoC test reports and collaborates with multiple TCB organizations to accelerate the FCC ID certification process.

FCC Test Item List

Test Item	Applicable Standard	Purpose
Radiated Emission	FCC Part 15.109/15.209	Measures electromagnetic waves in space
Conducted Emission	FCC Part 15.107	Measures interference on power lines
Occupied Bandwidth	FCC Part 15.215	Verifies spectrum utilization
Out-of-band Emission	FCC Part 15.205	Limits spurious signals
Power Density	FCC Part 15.247/15.407	Controls energy distribution
SAR RF Exposure	OET Bulletin 65	Evaluates radiation absorption by the human body

JJR Laboratory is equipped with Rohde & Schwarz and Keysight equipment to ensure precise and traceable data.

Certification Process and Lead Time

Pre-testing (3-5 days) → Troubleshooting/Rectification → Formal Testing (5-7 days) → Report Preparation (3 days) → TCB Review (7-14 days) → Certification Granted

Phase	Duration	JJR Service
Pre-testing	3-5 days	Rapid problem localization
Formal Testing	5-7 days	Full project coverage
Report & Review	10-17 days	Assistance with TCB submission

Total Lead Time: Approx. 2-4 weeks for SDoC, 4-8 weeks for FCC ID (including rectification time).

Fee Description

Certification Type	Price Range (USD)	Influencing Factors
FCC SDoC	$140 – $420	Product complexity
FCC ID	$1,100 – $3,500+	Number of frequency bands, number of rectifications

JJR Laboratory offers pre-testing packages; identifying issues early can reduce formal certification costs by 30% to 50%.

Common Failure Reasons and Rectification

High-Frequency Issues	Root Cause	JJR Solution
Excessive Radiation	Poor shielding/grounding issues	Shielding material recommendations + layout optimization
Excessive Conduction	Insufficient power filtering	Filter circuit design suggestions
Unqualified Spectrum	Deviation in modulation parameters	RF parameter debugging support

FCC Labeling Requirements

Certified products must be labeled with:

FCC ID (for Certification equipment) or SDoC Declaration of Conformity
Label Location: On the product body or specified in the user manual
Font Height: ≥ 1.5mm (standard requirement)

JJR Laboratory provides label template reviews to avoid customs clearance delays caused by labeling issues.

FCC vs. Other Certifications

Comparison Item	FCC (USA)	CE (Europe)	IC (Canada)
Test Standard	Part 15/18	EN 301 489	RSS-210/310
Issuing Body	TCB	Notified Body	FCB
Parallel Testing	—	Synchronizable with CE	Synchronizable with FCC

JJR Laboratory supports one-stop joint testing for FCC+CE+IC, saving on redundant testing costs.

Industry Case Studies

Case 1: TWS Bluetooth Earbuds

Challenge: 2.4GHz radiated band-edge exceeded limits.
JJR Solution: Optimized PCB antenna matching and added ferrite beads.
Result: Passed on the first try, lead time shortened to 3 weeks.

Case 2: Industrial WiFi Router

Challenge: 5.8GHz DFS testing was complex.
JJR Solution: Completed DFS parameter calibration during the pre-testing phase.
Result: Passed TCB review at once with no rectification needed.

Case 3: Smart Home Gateway

Challenge: Interference from multi-band coexistence.
JJR Solution: Time-division testing + spectrum isolation analysis.
Result: Simultaneously obtained FCC, CE, and IC certificates.

Frequently Asked Questions (FAQ)

Can I sell products in the U.S. without FCC certification?

No. E-commerce platforms like Amazon will delist the products, and Customs may seize the goods.

How long is the FCC certification valid?

There is no fixed expiration date; however, a re-evaluation is required if the product design changes.

Can I use reports from other laboratories?

Reports must be issued by an FCC-recognized laboratory; JJR holds full qualifications.

What if the test fails?

JJR provides free technical consultation to assist with rectifications until the product passes.

What is the difference between FCC ID and SDoC?

ID is for wireless products (intentional radiators), while SDoC is for standard electronic products (unintentional radiators).

Do "Verification" and "DoC" still exist?

No. After November 2017, they were merged into SDoC and are no longer used separately.
