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.

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.
