With ESPR now in force as the successor framework, the scope of mandatory design requirements is expanding well beyond energy consumption.

The actual requirements are set by product-category implementing regulations, each covering a defined scope (e.g. displays, motors, welding equipment). Each implementing regulation defines the applicable energy performance metrics, test methods, minimum performance thresholds, and labeling information requirements. ### Electronics categories currently in scope Implementing regulations cover a wide range of electronics: displays (Reg. 2019/2021), servers and data storage (Reg. 2019/424), uninterruptible power supplies (Reg. 2019/1782), welding equipment (Reg. 2019/1784), transformers (Reg. 2014/548), electric motors (Reg. 2019/1781), and external power supplies (Reg. 2019/1782). Products that appear similar may fall into different implementing regulations — the technical scope definitions matter and must be read carefully. ### Standby, off-mode, and networked standby power limits Many implementing regulations include mandatory standby and off-mode power limits. Products with network connectivity face additional networked standby limits — the device must reduce power consumption when connected to a network but not performing its primary function. Typical thresholds range from 0.5 W in off-mode to 2–8 W in networked standby depending on category. These limits apply at the design stage — they cannot be met through firmware-only patches after hardware is finalised. ### Product information requirements — labeling and technical documentation Each implementing regulation specifies what product information must appear on the product, its packaging, in the user manual, and in the technical file. This includes measured energy consumption figures, efficiency ratings, and sometimes a product data sheet conforming to a prescribed format. Failure to include this information is a labeling non-compliance under the implementing regulation — separate from any energy performance measurement failure. ## How to comply with ecodesign requirements for your product 01 Search the EUR-Lex Ecodesign database and the European Commission's Ecodesign working plan to confirm whether your product falls within an existing implementing regulation — check the scope definition carefully, as similar products may be in or out depending on specific technical characteristics. 02 Identify which energy performance parameters the implementing regulation requires you to measure — this could be standby power, seasonal energy efficiency ratio (SEER), energy efficiency index (EEI), or another metric defined specifically for your product category. 03 Commission energy efficiency measurements at an accredited test laboratory using the applicable EN test standard specified in the implementing regulation — for displays, EN 50564 covers standby; for servers, EN 50600-4 series applies; always verify the correct standard version against the regulation text. 04 Compile the required product information: include the mandatory energy declarations on packaging and in the user manual, prepare the product data sheet in the prescribed format if required, and document everything in the technical file alongside your CE marking documentation. 05 Declare conformity with the applicable implementing regulation in your Declaration of Conformity — list the specific regulation by number alongside the LVD, EMC, and other CE marking directives, since ecodesign compliance forms part of the CE marking framework for in-scope products. ## Frequently asked questions ### Does ecodesign compliance form part of CE marking? Yes. For products covered by an ecodesign implementing regulation, CE marking requires conformity with that regulation in addition to any other applicable directives (LVD, EMC, RoHS, etc.). The Declaration of Conformity must reference the implementing regulation by number, and the technical file must include the energy performance test results. A product that meets LVD and EMC requirements but fails ecodesign requirements cannot lawfully carry the CE mark. ### Which electronics products have mandatory standby power limits? Most electronics products covered by an ecodesign implementing regulation face standby power limits. Specific categories include displays (Reg. 2019/2021), external power supplies (Reg. 2019/1782), and household appliances. The limits vary by product type and connectivity — networked devices generally face a separate, slightly higher limit for networked standby mode than for non-networked standby. Check the specific implementing regulation for your product category to find the exact thresholds. ### How will ESPR change ecodesign requirements after 2025? The Ecodesign for Sustainable Products Regulation (ESPR, EU 2024/1781) replaces the Ecodesign Directive as the framework law and significantly expands its scope beyond energy-related products. ESPR enables requirements on durability, repairability, recyclability, recycled content, and carbon footprint — not just energy efficiency. Existing implementing regulations remain in force until replaced by ESPR delegated acts. The European Commission is expected to prioritise electronics, textiles, and construction products in its first wave of ESPR delegated acts from 2025 onwards. ### What testing standards measure standby power for electronics? EN 50564 is the primary standard for measuring standby and off-mode power consumption for information and communication technology equipment and networked standby equipment. For specific product categories, additional or alternative standards may apply — for example, EN ISO 22976 for welding equipment, or specific EN 50600 parts for data centres and server infrastructure. Always verify the applicable standard against the text of the relevant implementing regulation rather than assuming EN 50564 applies universally. **Disclaimer:** Educational resource only.
