DAB digital audio broadcasting certification did change in 2026 — but a lot of what's circulating has been exaggerated by brokers. The chip registry isn't mandatory. Standard automotive DAB can self-declare without a Notified Body. UKCA and EU test data remain interchangeable until 2028.

Let's go through each claim and separate fact from fiction. Some of these traps I've hit myself running certifications for clients.

1. WorldDAB Test Specification Upgrades from 3.1 to 4.0

WorldDAB released test specification version 4.0 in November 2025. Starting March 1, 2026, new applications for the WorldDAB logo must use the new version. Note: this applies to new applications only. Don't confuse it with renewing existing certificates.

1.1 New Test Items and Exemption Boundaries

Version 4.0 adds EPG (Electronic Program Guide) recovery and slideshow reception capability testing — both moved from optional to mandatory.

DAB+ audio decoder adds HE-AAC v2 parametric stereo verification. The old 3.1 version only tested up to HE-AAC v1, so this is a meaningful change.

Products with hardware that only supports v1 encoding and lacks a v2 decode path can be exempt from v2 testing. Only devices compatible with both v1 and v2 need full testing. Don't send incompatible products in for v2 testing — that's wasted money.

1.2 Who Actually Needs EWF Emergency Broadcasting

Emergency Warning Function (EWF) testing moved from optional to mandatory. Upon receiving an alert flag, the device must switch to the emergency broadcast channel within 2 seconds.

But here's the nuance: this 2-second switch is only mandatory for WorldDAB logo authorization testing. EU RED whole-vehicle type approval doesn't treat EWF as an RF compliance pass/fail item. Automaker OEM internal acceptance is where this gets checked.

UK DVSA and Germany KBA recommend using version 4.0 test reports, but there's no legal policy mandating rejection of 3.1 reports starting July 1, 2026. Existing 3.1 reports still work for new vehicle type applications. Brokers claiming everything must be redone on the new version? They want you to spend more.

  2. The Chip Registry Is Not a Mandatory Threshold

2.1 WorldDAB Chip Database Is Voluntary

The WorldDAB chip registry is a voluntary industry database. There's no mandatory regulation or hard industry threshold tied to it.

EU RED, UK UKCA, and GSO Gulf state radio access requirements don't check WorldDAB chip registration status. Your complete machine application won't be rejected because a chip isn't in the database. I've seen this sales pitch far too often.

Unregistered chips only mean you need to run additional chip baseline testing when applying for the WorldDAB logo. National statutory radio certification doesn't add mandatory extra test items. The "40% more test items, 2-3 weeks longer" claim is broker talk with no official backing. In my own projects, registered and unregistered chips had nearly identical certification timelines.

2.2 How to Use the Registry

The database is publicly searchable. Check it during chip selection — if the supplier's chip has pre-test records, you save some preliminary testing time.

No record isn't a dead end. It just means more work for the logo application. The complete machine certification path remains unaffected. Don't let it scare you.

  3. CE-RED Compliance Path and Standard Number Corrections

3.1 Standard Automotive DAB Can Self-Declare

DAB broadcast receivers fall under RED Article 3.2, supported by ETSI harmonized standard EN 303 345. Standard consumer-grade automotive DAB receivers are low-risk wireless devices.

After completing RF and EMC testing (an ILAC lab is sufficient), the manufacturer can self-declare via DoC. No Notified Body (NB) certificate required. Only public safety equipment and high-power broadcast transmitters mandate NB involvement for type examination.

Standard car infotainment doesn't need to pay for NB involvement. An ILAC lab report plus self-declaration is enough.

3.2 EN 303 345 Sub-part Numbering Corrected

The official ETSI sub-part numbers are:

·EN 303 345-2: AM broadcast

·EN 303 345-3: FM broadcast

·EN 303 345-4: DAB digital broadcast

Part -1 is the general overview. A DAB+FM+AM triple-band radio module tests each sub-part independently — they don't substitute for each other.

  4. UKCA and EU Test Data Still Mutually Recognized

4.1 No Need for Two Complete Test Suites Before 2028

After Brexit, UKCA and EU CE did split. But the period before January 1, 2028 is a parallel transition — EN 303 345 RF test data is mutually recognized on both sides.

The complete machine doesn't need a full retest. What needs to be separate? The complete technical file, declaration of conformity, and local responsible party — these must be compiled individually. The test data itself doesn't need to be redone.

There's no mandate for two complete test suites or doubled costs. Northern Ireland can use CE marking; Great Britain requires separate documents but shares test data.

4.2 Australia and Gulf States

Australia's ACMA uses AS 4943.2, which heavily overlaps with European EN 303 345 RF baseline limits. Most RF test data can be reused — just supplement Australia-specific band preliminary testing. No full retest needed.

Under the GSO Saber system, overseas ILAC labs upload qualification documents for online filing. Approval takes 3-5 weeks, not 8-12. Reports from filed labs are accepted across all seven Gulf states. Unfiled labs just can't issue Saber certificates — the reports themselves aren't worthless.

  5. KC Certification Timeline, Documents, and Samples

5.1 Don't Budget Based on the Longest Cycle

With a chip that has pre-test records, clean testing plus document review takes 3-5 weeks. One round of rework adds 1-2 weeks.

8-10 weeks is the longest cycle stacked with multiple rework rounds and chip preliminary testing. Don't quote that as your standard baseline to management — you'll have an awkward conversation when the timeline doesn't match.

5.2 Three Core Documents

Antenna spec sheet with gain values, complete functional matrix table, and hardware/software version numbers. Version inconsistency is the top reason for document rejection. Cross-check every line before submitting. I've reworked this for clients too many times.

5.3 Sample Submission

Negotiate sample quantity with the lab — 1 to 3 units works. No regulation mandates three units. Built-in integrated antennas go through coupling testing; no SMA connectors required.
