IECEE OD-2025-B — Certification Operational Document for the CB Scheme

IECEE OD-2025-B is a key operational document that governs the certification processes within the CB Scheme, focusing on the responsibilities and procedures for National Certification Bodies (NCBs). It complements the testing guidance of OD-2020 by addressing the certification lifecycle from application review to certificate issuance and post-certification surveillance. While OD-2020 focuses on the technical testing activities, OD-2025-B addresses the administrative and procedural aspects of the certification process.

The document is essential for certification managers and quality assurance professionals who need to understand how NCBs operate and what obligations they have toward manufacturers. OD-2025-B also provides manufacturers with a clear picture of what they can expect from an NCB throughout the certification process, including timelines, communication protocols, and recourse options if problems arise. This transparency is fundamental to maintaining trust in the CB Scheme.

Certificate Management and Lifecycle

The document defines four phases of the certificate lifecycle: application, evaluation, issuance, and maintenance. Each phase has specific requirements and time limits. An important feature is the provision for certificate amendments and extensions. If a manufacturer modifies a certified product, the NCB must assess whether the change affects safety or compliance before approving an amendment. The type of change determines the level of assessment required: minor changes may only need a document review, while major changes could require additional testing.

During the application phase, the NCB is responsible for confirming the scope of certification, identifying the applicable IEC standards and any relevant national deviations, and providing the manufacturer with a clear cost estimate and timeline. This initial scoping is critical because errors at this stage can lead to significant problems later. An incorrect standard selection could result in incomplete testing, while failure to identify applicable national deviations could prevent market access in specific countries.

The evaluation phase involves a thorough technical review of the product against the applicable standards. The NCB must verify that the CBTR is complete and accurate, that all required tests have been conducted with satisfactory results, and that the product labelling and documentation comply with the relevant requirements. Only after this comprehensive review can the certificate be issued. The issuance phase includes generating the certificate, entering it into the IECEE database, and notifying the manufacturer.

Surveillance and Market Access Monitoring

OD-2025-B requires NCBs to conduct periodic surveillance audits of certified products. These audits verify that production continues to meet the certified standards and that no unauthorised changes have been introduced. The frequency depends on the product category risk level: high-risk products (e.g., medical devices) require annual surveillance, while low-risk products may be audited every two to three years. Surveillance audits may be announced or unannounced, depending on the NCB's policies and the product risk assessment.

During a surveillance audit, the NCB reviews production records, inspects quality control procedures, and may select samples from the production line for testing. The audit also verifies that any changes to the product or production process have been properly notified and approved. If the audit identifies non-conformities, the manufacturer is given a defined period to implement corrective actions. Failure to address serious non-conformities within the required timeframe can result in certificate suspension or withdrawal.

Market surveillance is another important aspect of the maintenance phase. NCBs monitor their national markets for safety incidents involving certified products and may conduct random testing of products in the market to verify ongoing compliance. This market surveillance provides an additional layer of consumer protection and helps maintain the credibility of the CB Scheme.

Engineering Insight: Integrating Certification into Production

The most cost-effective approach is to embed certification requirements into the production quality management system from day one. Rather than treating certification as a separate compliance exercise, manufacturers should align their internal QC checkpoints with the CB Scheme requirements. This integration reduces surveillance audit findings and ensures that production deviations are caught before they become compliance issues.

A practical implementation of this integration is to include critical safety parameters on the production line inspection checklist. For example, if the certified design specifies a particular creepage distance on the PCB, the production line should have a visual inspection or automated test to verify that this distance is maintained in every production unit. Similarly, critical component specifications should be checked against the certified bill of materials during incoming inspection. This approach transforms compliance from a periodic audit event into an everyday production activity.

Manufacturers should also establish a formal change management process that requires engineering changes to be reviewed for certification impact before implementation. This review can be as simple as a checkbox on the engineering change order form asking whether the change affects any certified characteristic. If the answer is yes, the NCB must be consulted before the change is implemented. This simple step can prevent costly retroactive certification issues.

Cooperation Between NCBs and Cross-Border Recognition

The document also addresses how NCBs should cooperate across borders. When a certificate is issued in one country and used for national certification in another, the issuing and receiving NCBs must have a clear communication channel. OD-2025-B establishes templates for cross-border information exchange and defines the responsibilities of both parties in case of product safety incidents. This cooperation framework is essential for maintaining the mutual trust that underpins the entire CB Scheme.

In practice, when a manufacturer uses a CB certificate issued by NCB-A in Country A to obtain national certification from NCB-B in Country B, NCB-B must verify the validity of the certificate and check whether any national deviations apply. NCB-B may request supplementary information from NCB-A but should not require retesting unless the national deviations affect the test results. The cross-border cooperation procedures ensure that this process is efficient and transparent, with clear timelines for each step.
