On 2026年7月24日, Germany's TÜV Rheinland introduced a new edition of the EMC testing standards for photovoltaic cleaning equipment, covering EN 61000-6-2:2026+A1:2026 and EN 61000-6-4:2026+A1:2026.

The New Requirements and Expiration Date Have Been Clarified

Confirmed information shows that Germany's TÜV Rheinland officially introduced the new EMC testing standards EN 61000-6-2:2026+A1:2026 and EN 61000-6-4:2026+A1:2026 on 2026年7月24日. They apply to photovoltaic cleaning equipment sold in the European Union.

According to the summary, the new requirements require the relevant equipment to pass enhanced immunity testing, including radio-frequency immunity testing under simulated dusty conditions. At the same time, the expiration date of certificates issued under the previous edition has been confirmed as 2027年1月31日.

Based on the known facts, this standards update involves not only changes to testing requirements, but is also directly related to the validity of CE certification and equipment eligibility for EPC projects.

The Initial Impact Will Be on Market Access, Delivery, and Procurement

Exporters and Sellers Need to Reassess Market Access Conditions

The analysis indicates that companies selling photovoltaic cleaning equipment directly to the European Union market will be affected first. The reason is that the revised standards are related to CE certification validity, meaning that whether a product meets the new testing requirements may directly affect its compliance basis for entering the European Union market. At the business level, companies need to focus on the certificate status of existing models on sale, the transition timeline, and sales and delivery arrangements before and after 2027年1月31日.

Manufacturing and Integration Face Greater Testing and Verification Pressure

From an industry perspective, processing manufacturers and equipment integrators need to assess the products' adaptability under enhanced immunity testing. Although the information does not disclose a specific technical remediation path, it clearly identifies radio-frequency immunity under simulated dusty conditions as a new area of focus. This means that test preparation, prototype verification, and updates to certification documentation are becoming more important. For manufacturers, the impact is mainly reflected in product verification schedules and supporting certification arrangements, rather than merely in updates to sales documents.

EPC Procurement and Project Eligibility Assessment Will Become More Cautious

EPC project procurement parties and end users also need to pay attention simultaneously. The reason is straightforward: this upgrade has been explicitly linked to equipment eligibility for projects. For project procurement, equipment selection, and supplier management, it will be necessary to verify not only equipment functionality and delivery capabilities, but also whether the corresponding certificates remain valid and whether the relevant tests have been completed in accordance with the new edition.

Supply Chain and Fulfillment Coordination Are Becoming More Important

For supply chain service providers, channel distribution companies, and service providers responsible for delivery coordination, the impact of this change is mainly reflected in fulfillment coordination. The analysis indicates that the expiration date of certificates issued under the previous edition has been clarified, meaning that order execution, shipping arrangements, document preparation, and customer confirmation need to be more closely coordinated. Particularly in cross-border delivery scenarios, the certificate edition and validity period are likely to become key verification points affecting delivery continuity.

Key Practical Matters That Currently Deserve Attention

First Distinguish Between “Standard Introduction” and “Business Implementation”

What currently deserves greater attention is that the introduction of a standard and a company's completion of the actual transition are not the same thing. Relevant companies need to review official regulatory changes separately from the actual implementation status of their own products, existing orders, and target markets, avoiding a situation in which they merely know that “new regulations have been introduced” without implementing them at the level of models, certificates, and project lists.

Plan Backward from the Expiration Date of Existing Certificates

The 2027年1月31日 expiration date for certificates issued under the previous edition is currently the clearest business time signal. Whether they are manufacturers, trading companies, or project purchasers, all relevant parties should use this date to review existing certificate coverage, planned shipping schedules, and subsequent certification transitions, reducing communication and fulfillment risks caused by untimely certificate changes.

Carefully Verify Equipment Documentation for the European Union Market

For photovoltaic cleaning equipment sold in the European Union, companies should first verify the completeness of documentation related to the new EMC requirements, including compliance with the applicable testing requirements, certificate status, and the communication approach used with customers. The key is not to apply generalized management actions, but to clearly define the affected products and market scope and avoid handling non-European Union business together with European Union market access requirements.

Move Project Communication Forward to the Eligibility Confirmation Stage

For businesses involving equipment eligibility for EPC projects, relevant practitioners need to address certificate and standard-edition issues as early as possible during bidding, procurement, or supplier confirmation. The analysis indicates that if such matters are discovered only at a later stage of delivery, they often directly affect equipment eligibility assessments. Therefore, advance verification is more important than providing supplementary explanations afterward.

This Appears More Like a Clear Signal of Regulatory Tightening

From an observational perspective, this information is not merely an update to a standard number, but a further clarification of the boundaries of compliance requirements for photovoltaic operation and maintenance equipment. In particular, the inclusion of enhanced immunity testing and radio-frequency immunity under simulated dusty conditions in the scope of attention indicates that the electromagnetic adaptability requirements for relevant equipment in specific operating environments are being examined more strictly.

At the same time, this development is currently better understood as a compliance change that has entered the implementation stage, rather than a directional signal still limited to discussion. The reason is that both the introduction date and the expiration date of certificates issued under the previous edition have been clarified, and the impact has been directly linked to CE certification validity and equipment eligibility for EPC projects. However, the specific implementation standards and the way the transition will be handled in different business scenarios still require continued observation.

For the Industry, the Focus Is on Coordination Rather Than Reaction

Overall, the core message conveyed by Germany's TÜV Rheinland's update to the EMC testing standards for photovoltaic operation and maintenance equipment is that the compliance threshold for equipment related to the European Union market has undergone a clear adjustment, and that this adjustment is directly related to market access, project procurement, and fulfillment arrangements.

Viewed rationally, this does not mean that all impacts will appear simultaneously, but it is also inappropriate to regard it merely as a general standards update notice. It is currently more appropriate to understand it as an industry development with a clearly defined timeline, requiring relevant parties throughout the industrial chain to complete verification and coordination as soon as possible. Continued attention should be paid to its specific implementation in certification processes and project eligibility requirements.

Basis of This Article and Directions for Further Verification

This article was generated based on the information title, event date, and event summary provided by the user. The core information includes Germany's TÜV Rheinland introducing new EMC testing standards, certificates issued under the previous edition becoming invalid on 2027年1月31日, and the impact of this change on CE certification validity and equipment eligibility for EPC projects.

For this type of industry information, further verification can generally be conducted by consulting official announcements, company announcements, industry association information, reports from authoritative media, and documents issued by standards organizations.
