Full title and description

IECRE OD-554-1:2021 — Type Certification Scheme for small wind turbines (Edition 1.0). This IECRE Operation Document defines the certification scheme, modules and assessment requirements used by IECRE-recognised certification bodies to carry out type/prototype/component certification of small wind turbines (small wind turbine type certification procedures and associated verification and testing requirements).

Abstract

The document establishes a modular Type Certification Scheme tailored to small wind turbines (commonly referenced for turbines with rotor-swept area up to 200 m2). It sets out the required evidence, test programmes (design, static/strength tests, functional and safety tests, power performance and—where applicable—acoustic tests), manufacturing conformity checks and surveillance needed to issue and maintain an IECRE certificate for a small wind turbine type. The scheme references the relevant parts of the IEC 61400 series and other normative standards used for design, testing and verification.

Scope

Defines the certification procedure and mandatory/optional certification modules for type, prototype and component certification of small wind turbines (commonly applied to turbines with rotor-swept area up to 200 m2). The scope includes requirements for design evaluation, type testing (strength, functional and safety tests, power performance, acoustic where relevant), factory production control / manufacturing conformity assessment, reporting and surveillance required to issue, renew and maintain certificates under the IECRE scheme. The document cross-references the applicable IEC 61400-series and other standards used to demonstrate conformity.

Key topics and requirements

• Applicability and limits (small wind turbine classification, typical rotor-swept area threshold up to 200 m2 for OD-554-1 usage).
• Modular certification structure (design evaluation, type testing, manufacturing conformity, documentation review, factory inspection and surveillance).
• Mandatory tests and verifications: structural/strength tests (tower and rotor/rotor components), functional and safety system testing, required operational/duration testing and power performance measurements; acoustic noise measurement where required by market/jurisdiction.
• References to IEC 61400-series standards (design, measurement, acoustic and load measurements) and to IECRE OD documents for related activities (e.g., project certification and type/component scheme rules).
• Requirements for certification reports, minimum contents and evidence (test records, manuals, safety assessments) and certification validity / surveillance rules.
• Guidance for prototype certificates and transitional provisions where national regulations reference or adopt IECRE OD-554-1 as their certification baseline.

Typical use and users

Primary users are IECRE-recognised certification bodies, notified and accredited test laboratories, and third-party conformity assessment bodies; manufacturers and designers of small wind turbines seeking international recognition of type or prototype certificates; regulators and procurement authorities that accept or reference IECRE certification; consultants and test houses performing the tests and preparing certification dossiers. Certification scheme users include organisations providing type certification and market access for distributed and small-scale wind equipment.

Related standards

OD-554-1 is normally applied together with and references multiple IEC (and adopted national) standards from the IEC 61400 family and related documents, for example: IEC 61400-1 (design), IEC 61400-2 (small wind turbines), IEC 61400-11 (acoustics), IEC 61400-12 (power performance), IEC 61400-23 (full-scale blade testing) and other wind-sector technical documents; and other IECRE Operation Documents (for example OD-501/OD-502 series for type and project certification where applicable). National/regional small-wind standards (e.g., ACP/ANSI, MCS, UL/other national schemes) are frequently referenced for market-specific requirements.

FAQ

Q: What is this standard?

A: IECRE OD-554-1:2021 is an IECRE Operation Document (Edition 1.0) that sets out the Type Certification Scheme specifically for small wind turbines; it defines the modules, test and assessment requirements and procedures used by IECRE-recognised certification bodies for issuing type/prototype/component certificates for small turbines.

Q: What does it cover?

A: It covers the certification process for small wind turbines: applicability limits (commonly up to 200 m2 rotor-swept area for the OD-554-1 application), required design and test evidence (structural strength tests, functional and safety tests, power performance and acoustic measurements where applicable), manufacturing conformity, certification reporting and surveillance. It also references the IEC 61400 family and other standards that provide the technical test methods and requirements.

Q: Who typically uses it?

A: Certification bodies and accreditation schemes, test laboratories, manufacturers of small wind turbines seeking internationally-recognised type or prototype certification, national regulators that reference IECRE procedures, and consultants/test houses preparing certification dossiers.

Q: Is it current or superseded?

A: Edition 1.0 (2021) is the published IECRE Operation Document for OD-554-1 and is listed as active in document distributors and regulatory references; users should verify with IEC/IECRE or national authorities for any later revisions or related OD updates. For related schemes covering larger turbines see IECRE OD-501 (and OD-502 for project certification).

Q: Is it part of a series?

A: Yes — OD-554-1 is part of the IECRE family of Operation Documents that implement certification schemes and procedures; it operates alongside other IECRE ODs (for example OD-501/OD-502 series for broader type, component and project certification) and is intended to be used with the IEC 61400 series of technical standards.

Q: What are the key keywords?

A: small wind turbine, type certification, prototype certificate, IECRE, OD-554-1, IEC 61400, power performance, acoustic testing, structural strength tests, manufacturing conformity.
