EV charger If your company is expanding into Singapore, don’t miss this “must-have requirement”! — The Singapore TR25 certification is the only requirement for legally entering the Singaporean market, and it serves as an authoritative endorsement of safety and quality.
01
What are the specific requirements for TR25 certification?
As a core technical specification led by the Land Transport Authority (LTA) of Singapore, TR25 is by no means a mere formality; its specific requirements are detailed and stringent:
First, there are precise classification criteria
AC Charging StationMust meet the following requirementsTR25-1:2022 Requirements,DC Charging StationThen, based onPower and Configuration: “The Right Fit”", DC charging stations with a power rating greater than 200 kW, or those with a power rating of 150 kW or higher that include thermal management and automatic connection features, must undergo more stringentTR25-3 Test;
Next are the core technical requirements
IncludingCharging PortMust be compatibleIEC 62196 Standard, featuring a triple protection mechanism against overcurrent, short circuits, and electrical leakage,Communication ProtocolsSupport requiredOCPP 1.6J and later versionsto enable remote monitoring;
In addition, product labeling must clearly display the certification number, the LTA compliance QR code, and the emergency stop button.

Why Are Companies Racing to Obtain TR25 Certification?
• A Foot in the Door in the Market: Without TR25 certification, it is not possible to obtain a Letter of No Objection (LNO) from the LTA, nor is it possible to affix compliance labels and begin sales;
• Comprehensive Protection: Not only does it comply with internationally recognized electrical safety and EMC requirements, but it also incorporates localized tests—such as those for solar radiation, vibration, and shock—tailored to Singapore’s hot, humid, and high-salt-fog environment, and must pass a durability test involving 1,000 insertion and removal cycles;
• Valid for an extended period: The certification is valid for 5 years; passing the exam on the first try ensures a stable market position.

Get certified early to secure your spot! Here’s a super clear guide to the certification process.
1. Preparing Materials: Submit documents such as product specifications, circuit diagrams, and ISO system certificates, and identify a local authorized representative;
2. Testing and Submission for Inspection: Provide samples; the Arnool lab will coordinate and complete the three core tests—electrical safety, EMC, and localized environment—while monitoring progress and providing data feedback throughout the process.
3. Report Review: After the laboratory issues the test report, submit it to the LTA-designated agency for review and, at the same time, complete the IMDA registration (if wireless functionality is included);
4. Obtaining a Certificate: Once approved, collect the TR25 certification and the LNO letter of no objection, affix the compliance label, and the product is ready for market release.
