IECEE 02-2 defines the detailed rules of procedure for the operation of the IECEE CB Scheme, complementing the constitutional framework of IECEE 01. It addresses the practical mechanisms of certification, including application processing, test report acceptance, deviation handling, and dispute resolution between member bodies. While IECEE 01 answers the question of “what” the CB Scheme is, IECEE 02-2 answers “how” it actually works in practice.
The rules of procedure are essential reading for anyone involved in product certification, as they govern the day-to-day interactions between manufacturers, NCBs, and TLs. Understanding these rules allows manufacturers to navigate the certification process efficiently, anticipate potential roadblocks, and protect their rights when disputes arise. The document has been developed and refined over many years of practical experience, incorporating lessons learned from thousands of certification cases worldwide.
The rules specify that each application must include a complete set of technical documentation: product description, schematics, bill of materials, and the relevant IEC standards list. The NCB reviews the documentation within 15 working days and either accepts or requests supplementary information. Once testing is complete, the CBTR must be issued within 30 days. These time limits are designed to prevent unnecessary delays and hold all parties accountable for their responsibilities in the certification process.
The documentation requirements are carefully specified to ensure that the NCB has sufficient information to make a thorough assessment without imposing an unreasonable burden on the manufacturer. Key documents include electrical schematics, PCB layout diagrams, component specifications and certifications, parts lists, material declarations, and user manuals. For complex products, additional documentation such as software architecture descriptions or thermal simulation reports may be required. The NCB may also request samples for preliminary evaluation before formal testing begins.
| Process Step | Responsible Party | Time Limit | Deliverable |
|---|---|---|---|
| Application submission | Manufacturer | — | Completed application form + technical file |
| Document review | NCB | 15 working days | Acceptance or request for supplementary info |
| Product testing | TL | As agreed (typically 4–8 weeks) | Test data and observations |
| CBTR issuance | NCB / TL | 30 days post-test | Complete CB Test Report |
| National certification | Member NCB | 30 working days | National certification mark or refusal |
One of the most critical aspects of IECEE 02-2 is the handling of national deviations. Each member country may declare deviations from IEC standards based on local regulations, voltage differences, or climate conditions. These deviations are published and must be tested for when a manufacturer seeks national certification in that country. The standard classifies deviations into three categories: safety, EMC, and installation requirements. Each category has its own review and approval process within the CB Scheme framework.
National deviations arise from legitimate differences in national regulatory frameworks. For example, a country with a 100 V mains voltage may have different requirements for creepage distances and clearances compared to a country with 230 V. Similarly, countries in tropical climates may impose stricter requirements for humidity resistance and corrosion protection. Understanding these differences and incorporating them into product design from the outset is essential for successful global market access.
The deviations database maintained by the IECEE Secretariat is continuously updated as countries modify their national regulations. As of 2026, there are over 1,500 active national deviations registered across all member countries, covering everything from plug configurations to specific material restrictions. Navigation of this complex landscape requires both technical expertise and up-to-date information.
For global product launches, engineers should map all applicable national deviations at the design stage. A common mistake is designing to the base IEC standard only, then discovering that a particular country requires a different creepage distance or thermal class. Incorporating deviation requirements into the initial design reduces certification risk and avoids costly last-minute PCB redesigns. A systematic deviation mapping exercise at the concept phase can identify potential conflicts before they become embedded in the design.
Best practice is to create a deviation compliance matrix that lists each target country, its declared deviations, the corresponding design requirement, and the verification method. This matrix serves as a living document throughout the product development lifecycle, ensuring that no country-specific requirement is overlooked. Many experienced certification teams maintain a library of deviation matrices for different product categories, which can be adapted and reused for successive product generations.
IECEE 02-2 establishes a formal dispute resolution process. If a manufacturer believes an NCB has incorrectly rejected a CBTR, it may appeal first to the NCB itself, then to the Certification Body Committee, and finally to the Management Committee. The process is designed to be completed within 90 days, ensuring that disputes do not unduly delay market access. Each level of appeal provides an increasingly independent review of the dispute, with the Management Committee serving as the final arbiter.
The appeals process begins with a written submission detailing the grounds for appeal, supported by relevant technical evidence. The NCB must respond within 30 days, providing a reasoned justification for its decision. If the manufacturer is not satisfied with the response, the case is escalated to the CB Committee, which appoints an independent panel of experts to review the technical merits of the dispute. The panel's recommendation is then presented to the Management Committee for a final decision.
