Full title and description

St IECRE OD-550-4-2025 — IECRE Operational Document OD‑550‑4:2025. Operational guidance for conformity assessment activities within the IECRE scheme addressing procedures, responsibilities and evidence requirements for certification of renewable-energy electrical balance‑of‑plant components and associated testing (operational document, 2025 edition).

Abstract

This operational document (OD‑550‑4:2025) provides prescriptive guidance for IECRE conformity assessment bodies, testing laboratories and applicants relating to the certification pathway for electrical balance‑of‑plant components used in renewable energy systems. It clarifies procedural steps, recordkeeping, roles of RECB/RETL/RECS participants, typical test evidence, witness testing arrangements and reporting formats intended to harmonize assessments and improve cross‑jurisdictional acceptance of test results under the IECRE scheme.

Scope

OD‑550‑4:2025 defines the administrative and technical requirements for conducting conformity assessments of electrical balance‑of‑plant equipment and assemblies within the IECRE scheme. The document covers application and acceptance criteria, test evidence and data quality, witness testing procedures, roles and responsibilities of RECB/RETL/RECS actors, reporting templates, and provisions for atypical products or new technologies where additional justification is required. It is intended to be used alongside relevant IEC normative standards (product and test standards) and other IECRE operational documents.

Key topics and requirements

• Scope and applicability for electrical balance‑of‑plant components (transformers, switchgear, converters, protection devices and cabling assemblies).
• Application submission requirements and mandatory evidence checklist (type test reports, production quality records, factory inspection documentation).
• Requirements for test laboratories (RETL) including accreditation, validated methods, measurement uncertainty and data traceability.
• Witness testing rules: when witnessing is required, witness planning, roles of witnesses and acceptable deviations.
• Reporting format and minimum content for test reports and conformity statements to ensure mutual recognition.
• Rules for managing non‑conformities, corrective actions and re‑assessment procedures.
• Special provisions for novel technologies, prototype testing and staged certification approaches.
• Confidentiality, data sharing, and handling of proprietary information within IECRE processes.

Typical use and users

Primary users are IECRE conformity assessment bodies (RECBs), IECRE‑recognised testing laboratories (RETLs), certification scheme managers (RECS), product manufacturers and suppliers of electrical balance‑of‑plant equipment, test engineers, regulatory authorities and procurement organizations involved in renewable energy projects. The document is used during certification planning, submission review, test witnessing, and final reporting to ensure consistent application of IECRE requirements.

Related standards

OD‑550‑4:2025 is intended to be used in conjunction with the IECRE suite of operational documents and relevant IEC product and test standards. Typical related documents and standards include: IECRE OD series (other OD documents for scheme rules and witness testing), IEC 61400 series (wind turbine systems) where applicable, IEC 61400‑12, IEC 61000 series (electromagnetic compatibility), IEC 60076 (power transformers), IEC 62271 (high‑voltage switchgear), and other IEC product test standards referenced by product family.
