About This Item
IEC 61558-2-13:2022 provides the technical basis for evaluating auto-transformers and power supply units incorporating auto-transformers for general applications. It is intended for engineering teams, laboratories, and compliance professionals that need a reliable compliance reference for safety-focused product evaluation, documentation review, and conformity assessment. As the third edition of IEC 61558-2-13:2022, it supports structured technical assessment of equipment covered by the title, helping organizations align design verification, procurement checks, and testing workflows with a recognized safety framework.
Purpose of IEC 61558-2-13:2022
The purpose of IEC 61558-2-13:2022 is to define particular requirements and tests for auto-transformers and power supply units incorporating auto-transformers used in general applications. In practice, it helps establish a focused technical specification for product evaluation, with attention to safety-related design verification and laboratory evaluation. Organizations use it to support documented evaluation, risk management, and technical review activities when assessing whether an electrical equipment design or sourced component is suitable for compliance-oriented development and quality workflows.
Compliance applications of IEC 61558-2-13:2022
IEC 61558-2-13:2022 is commonly used in conformity assessment, supplier qualification, and product validation programs for transformer-based power conversion equipment. It may support test planning, engineering documentation, and regulatory preparation where auto-transformers are part of the final product or internal power architecture. For procurement teams and compliance engineers, it can serve as a practical reference during specification review, sample testing, and technical validation, especially when assessing safety performance within broader electrical equipment workflows.
Benefits of IEC 61558-2-13:2022
Using IEC 61558-2-13:2022 can improve consistency in safety evaluation and help reduce uncertainty during design and verification activities. It supports more repeatable testing workflows, clearer technical acceptance criteria, and better alignment between engineering teams, laboratories, and procurement functions. For organizations preparing conformity assessment documentation, it may also strengthen traceability and risk reduction by providing a recognized compliance reference for auto-transformers and related power supply units. This can be valuable when managing product lifecycle decisions and operational consistency.
