The EU updates CE guidelines, RTO/RCO need to take into account both energy efficiency and explosion protection

After the European Commission updated the "CE Mark Implementation Guidelines (2026 Revised Edition)" on August 11, 2026, the EU access requirements for RTO/RCO exhaust gas treatment systems have become clearer and dual constraints: on the one hand, they must meet the relevant explosion-proof safety requirements of EN 1539, and on the other hand, they must also meet the requirements for energy efficiency classification and actual measurement verification of VOCs treatment equipment in the new Appendix XVII. For manufacturers, testing agencies, certification service providers, and procurement and delivery links exporting to the EU, this is not only an adjustment at the document level, but also directly related to the type inspection path, test arrangements, and technical data preparation methods, and is worthy of continued follow-up.

After CE guideline update, RTO/RCO enters dual compliance path

According to the "CE Mark Implementation Guidelines (2026 Revised Edition)" released by the European Commission's official website on August 11, 2026, starting from January 1, 2027, all RTO/RCO exhaust gas treatment systems imported into the EU must meet the dual compliance requirements of EN 1539 (Explosion-proof Safety of Industrial Heat Treatment Equipment) and the new Appendix XVII (Energy Efficiency Classification and Actual Measurement Verification of VOCs Treatment Equipment). The document also increases the RTO heat recovery efficiency threshold to no less than 92%, which is higher than the original standard of 85%, and requires third-party laboratories to issue joint energy efficiency and ATEX test reports that include on-site working condition simulation. Confirmed information also includes that this adjustment will directly affect the type inspection path, certification cycle and technical document preparation of Chinese export manufacturers.

All links in the industry chain have begun to recalibrate

Export manufacturers need to deal with both performance and safety lines simultaneously

For RTO/RCO equipment manufacturers that directly export to the EU, the most direct impact is not the improvement of a single indicator, but the parallelization of testing and certification logic. In the past, it may only be necessary to prepare materials around a certain type of performance or safety documents, but now it is necessary to put heat recovery efficiency, on-site working condition simulation and explosion-proof safety requirements under the same set of declaration and verification framework. From an analysis point of view, this will increase the coordination costs of early design confirmation, prototype testing, technical document compilation and laboratory scheduling.

The workload of testing and certification services will be lengthened

Third-party laboratories and certification service agencies will face more complex test combinations. The joint test report must not only cover energy efficiency results, but also include ATEX-related verification and reflect on-site working condition simulations. For this type of service organization, changes are mainly reflected in the arrangement of test plans, the completeness of the evidence chain and the report delivery cycle. Observation shows that such requirements usually raise the threshold for preparation for inspection and increase the risk of data rework.

Purchasers and project deliverers will pay more attention to pre-confirmation

Purchasers, general contractors and equipment integrators for EU projects will need to lock in compliance in advance in bidding documents, technical agreements and acceptance clauses. Since the new requirements involve energy efficiency thresholds, test methods and joint reporting formats, if the procurement process is still organized according to the old standards, it is easy to face the pressure of supplementary parts and review during the delivery, acceptance or customs clearance process. From a business process perspective, the impact will focus on technical clarification, contract confirmation and delivery cycle management.

What preparatory actions should we focus on now

First check whether the product has been re-evaluated according to the 92% threshold

Enterprises must first confirm whether the heat recovery efficiency of existing RTO products has been re-evaluated according to the requirement of ≥92%, rather than continuing the old internal caliber of 85%. For models that are planned to continue to be exported to the EU, relevant test records, design parameters and performance statements need to be updated simultaneously to avoid inconsistencies between technical documents and the new version of the guidelines.

Make joint test data into a complete chain of traceability

Since the new requirements emphasize joint testing of energy efficiency and ATEX, companies should pay attention to whether the report has traceable prototype information, test conditions, on-site working condition simulation instructions, and result correspondence. From an analysis point of view, the follow-up review is likely to focus not only on the conclusion itself, but also on whether the testing process is consistent with the declared model and whether the technical documents can support the certification conclusion.

Impacts delivery pace and supplier selection in advance

If a company relies on external laboratory or certification service resources, scheduling and data completeness will directly affect order delivery. A more suitable approach at present is to incorporate the certification window, sample preparation for inspection, data translation and version control into the project plan as early as possible, and at the same time conduct consistency checks on key accessories, technical documents and after-sales support responsibilities in the supply chain. This can reduce the need to do additional testing or reorganize files just before shipment.

This is more like an execution signal, rather than a simple file update

From an industry perspective, this information is more suitable to be understood as a clear execution signal, rather than a regular revision that stays at the text level. The reason is that it not only raises the energy efficiency threshold, but also puts explosion-proof safety and energy efficiency actual testing into the same compliance framework, and requires third-party laboratories to provide joint test reports. According to analysis, such changes usually affect export enterprises and certification chains first, and then gradually spread to procurement, bidding and acceptance links. What deserves more attention at this stage is not the excessive deduction of the rules, but the subsequent official enforcement caliber, test report acceptance method and whether the project bidding documents will be adjusted accordingly.

What we will focus on in the short term is the enforcement details and corporate enforcement

Overall, this information has released a strong signal of tightening compliance, but its final enforcement method, information details and review focus still need to continue to be observed. For relevant enterprises, it is currently more suitable to understand it as a compliance change that must be prepared in advance, rather than as background information that can be processed until it is close to taking effect. What will really affect the pace of the market is how subsequent certification agencies, laboratories and procurement parties convert this new set of requirements into operable documents and acceptance standards.
