UAE.S 5021:2018 certification is far more than just a "product qualification certificate." Especially starting in 2025, it has added numerous technical thresholds and quietly expanded its scope of applicable products. Below, I’ll break down its core test items and the products that are mandatory for certification in detail.

I. UAE.S5021:2018 Certification Standard Items

The technical "test bank" for this certification is divided into basic mandatory items and the latest supplementary items. Basic items apply to all devices, while supplementary items target specific product types—and requirements are updated annually.

1. Basic & Core Test Items

These are "hard indicators" all DAB/DAB+ receiving devices must pass, with the core goal of ensuring stable signal reception and clear sound quality:

·RF (Radio Frequency) Performance Testing: This is the top priority. It mainly verifies the device’s ability to capture signals in complex environments, with key indicators including:· Reception Sensitivity: Usually required to be ≤-85dBm to ensure normal listening in weak-signal areas.· Anti-Interference Capability: Includes adjacent channel suppression (required to be ≥40dB) and multipath interference resistance, simulating signal fluctuations in moving vehicles or home environments.

·Audio Quality Testing: Ensures the high-fidelity characteristics of digital broadcasting. Key metrics include total harmonic distortion (THD), typically required to be ≤1%, and frequency response range (e.g., 20Hz-15kHz).

·Electromagnetic Compatibility (EMC) Testing: Based on standards like EN 55032, ensures the device’s electromagnetic radiation meets limits and that it can resist external electromagnetic interference—preventing disruption to other electronic products in vehicles or homes.

·Basic Function & Safety Testing: Includes hardware evaluation, user interface checks, and electrical safety testing.

2. New & Enhanced Specialized Tests (2025 Onward)

This is where the most significant changes lie, reflecting the UAE’s new requirements for device intelligence and security:

·Mandatory Emergency Warning System (EWS): All in-vehicle devices must support the EWS, with a response time of no more than 3 seconds from signal reception to playback. This is a core public safety feature.

·Cybersecurity Protocols: For connected smart devices (e.g., IoT in-vehicle systems, smart speakers), compliance with cybersecurity protocols like UNECE R155 is now mandatory to prevent broadcast signal hijacking.

·Extreme Environmental Adaptability: Tailored to the UAE’s high-temperature climate, in-vehicle devices must pass rigorous temperature cycle tests (-40°C to 85°C) and vibration tests to ensure reliability and durability.

·Energy Efficiency & Labeling Requirements: Devices with charging functions must have standby power consumption ≤0.5W. Starting September 2025, products must use the new ECAS energy efficiency label.

·Language & Localization: The user interface and functions must support Arabic.

  II. Mandatory Product Scope for UAE.S5021:2018 Certification

Many people assume this is only for in-vehicle radios—but that’s not the case. According to regulations and 2025 updates, the mandatory scope is clear and expanded:

1. Traditionally Mandatory Categories (Since Standard Inception)

·In-Vehicle Audio Equipment: Integrated in-vehicle radios, aftermarket DAB+ receivers, etc. Per official resolutions, starting with 2024 model year vehicles, all broadcast reception devices in cars sold in the UAE must fully comply with this standard.

·Home Audio Equipment: Home theater systems, tabletop radios, music systems, etc.

·Portable Devices: Portable radios, MP3/MP4 players with DAB+ functionality, etc.

2. Newly Mandatory Categories (2025 Onward)

These changes require special attention, as the scope now extends to consumer electronics:

·Smart Wearables: For example, smartwatches supporting DAB+ broadcast functionality.

·IoT In-Vehicle Infotainment Systems: Highly connected, intelligent in-vehicle systems. In addition to basic functions, they must integrate the aforementioned Emergency Warning System (EWS) and Arabic interface.

·Narrowed Exemptions: Previously, simple AM/FM-only devices might have been exempt. Now, if such devices add wireless features like Bluetooth or Wi-Fi, mandatory certification is required.

Simply put, if your product has DAB/DAB+ receiving functionality and is intended for sale in the UAE—whether installed in a car, placed at home, worn on the body, or connected to the internet—it’s almost impossible to avoid this certification.
