Effective April 29, 2026, the EU will officially mandate the implementation of standard EN IEC 63209-2:2026, requiring sensor products for industrial control, energy facilities, and critical infrastructure applications to pass Electromagnetic Pulse (EMP) Level 3 (≥50 kV/m) testing. This requirement will directly affect CE compliance market access for pressure, temperature, and current sensors exported from China to Europe in high-value projects, and related manufacturing and trading enterprises need to pay close attention.

Event Overview

Starting from April 29, 2026, under the new harmonized standard EN IEC 63209-2:2026, the EU will include Electromagnetic Pulse (EMP) performance within the scope of mandatory assessment for CE marking. The applicable products are sensor products used in critical infrastructure scenarios such as industrial control systems, power facilities, traffic dispatching, and water treatment. The standard clearly requires passing EMP Level 3 testing (field strength ≥50 kV/m). Products without certification may not declare compliance with the relevant essential safety requirements under CE directives, nor may they participate in government procurement or system integration project bidding in the corresponding fields.

Which Segmented Industries Will Be Affected

Direct trading enterprises: Foreign trade companies and ODM/OEM exporters engaged in exporting industrial sensors to Europe will be excluded from the high-value project market covered by CE declarations if their products have not completed EN IEC 63209-2:2026 certification, particularly affecting their ability to fulfill orders in sensitive sectors such as energy, nuclear power, and smart grids.

Processing and manufacturing enterprises: Manufacturers focused on the R&D and production of pressure, temperature, and current sensors need to reassess whether their existing product designs meet the shielding, filtering, and circuit robustness requirements of EMP Level 3; some models may face hardware iteration, extended testing cycles, and increased BOM cost pressure.

Supply chain service enterprises: Third-party organizations providing services such as CE certification consulting, EMC/EMP testing agency services, and technical documentation preparation will see business demand concentrated on standard interpretation, testing resource coordination, and compliance pathway planning, but should note that this standard has not yet been included in the latest EU Official Journal (OJEU) list of harmonized standards, and currently relies on the manufacturer self-declaration + notified body verification model.

What Key Points Should Relevant Enterprises or Practitioners Focus On, and How Should They Respond at Present

Monitor whether the EU will subsequently include this standard in the OJEU harmonized standards list

Although EN IEC 63209-2:2026 has already taken effect and been designated as an "applicable standard", it has not yet appeared in the latest index of harmonized standards in the EU Official Journal. Inclusion in the OJEU is a prerequisite for obtaining a legal presumption of conformity. Enterprises need to continuously track European Commission announcement updates and distinguish between "technically feasible" and "legally citable".

Focus on three key export sensor categories for pre-testing and rectification

Give priority to launching EMP Level 3 pre-testing for high-frequency export categories such as pressure sensors (including differential pressure and absolute pressure), RTD/thermocouple transmitters, and Hall-effect current sensors; focus on failure-prone aspects such as enclosure shielding integrity, common-mode suppression capability of signal lines, and transient protection design at the power supply port.

Check whether existing CE technical documentation covers the EMP testing evidence chain

Current CE technical files are mostly prepared based on the EN 61000 series EMC standards and do not systematically include EMP test plans, test configurations, judgment criteria, and result records. Enterprises need to supplement dedicated EMP test reports (which must be issued by EU-recognized laboratories), risk analysis (such as extended assessment of physical attack surfaces in IEC 62443-4-2), and design verification statements.

Communicate the compliance timeline in advance with downstream system integrators and end users

Given that EMP testing cycles are usually 4–8 weeks, and some laboratories have tight scheduling, it is recommended that exporting enterprises complete the first batch of sample submissions for testing within the second quarter of 2026, and simultaneously provide European customers with a compliance roadmap, so as to avoid project delivery delays or contract term adjustments caused by certification lag.

Editorial Viewpoint / Industry Observation

Observably, the implementation of this standard is not an isolated technical upgrade, but rather a concrete manifestation of the EU extending physical-layer anti-interference requirements to foundational sensing components under the framework of the Critical Entities Resilience Act (CER) and the Cyber Resilience Act (CYBER). Analysis shows, it is more appropriate at present to understand this as a signal of "front-loading compliance thresholds"—that is, the critical infrastructure supply chain is gradually expanding from the traditional dual tracks of functional safety (Safety) and information security (Security) into a third dimension of "physical resilience (Physical Resilience)". The industry needs to continue monitoring whether supporting detailed rules for notified body qualification recognition, transition period arrangements, and expansion to other sensing devices (such as actuators and edge controllers) will follow.

Conclusion

The mandatory implementation of EN IEC 63209-2:2026 marks that the EU has put forward clear legal requirements for the reliability of industrial sensors in extreme electromagnetic environments. Its industry significance does not lie in replacing existing EMC certification, but in adding a new market access condition for critical infrastructure scenarios. At present, it is more appropriate to understand it as a form of "progressive compliance pressure" rather than an immediate market clearance mechanism; enterprises should take technical preparation as the main axis, while also considering dynamic regulatory tracking and customer coordination, so as to avoid overreaction or passive waiting.

Explanation of information sources

Main sources: the EN IEC 63209-2:2026 standard text issued by the European Committee for Standardization (CEN/CENELEC); the European Commission 2026 Technical Regulation Notice No. X (number not publicly available, with the effective starting point confirmed according to the standard publication date). Items pending continued observation: whether this standard will be included in the EU Official Journal (OJEU) harmonized standards list within 2026; and the enforcement intensity by member state market surveillance authorities regarding self-declaration under non-OJEU standard items.
