Overview
SIST EN 60404-2:2002/A1:2008 is a European standard that specifies the methods for measuring the magnetic properties of electrical steel sheet and strip using an Epstein frame. Developed by the Slovenian Institute for Standardization (SIST), this standard aligns with international IEC and EN requirements and incorporates the corrigendum of March 2018. The document is essential for ensuring the quality and uniformity of test results in the characterization of magnetic materials-critical for the electrical engineering and manufacturing industries.
Key Topics
Key areas addressed in this standard include:
- Measurement Methods: Procedures for determining core magnetic properties such as magnetic flux density, specific total loss, and related parameters in electrical steel sheet and strip.
- Application of Epstein Frame: Detailed instructions for sample preparation, test setup, and usage of the Epstein frame-a widely accepted apparatus for magnetic testing.
- Digital Sampling Techniques: Integration of modern digital sampling methods for capturing and analyzing voltage and current signals accurately.
- Uncertainty and Calibration: Guidance for minimizing measurement uncertainty and calibrating equipment, especially with digital technologies.
- Reference Materials: Emphasis on using precisely defined test procedures for consistency and comparability of results.
Applications
SIST EN 60404-2:2002/A1:2008 has broad applications across the field of electrical engineering and magnetic material testing:
- Quality Control: Used by manufacturers of electrical steel to ensure products meet stringent magnetic performance criteria.
- Research and Development: Facilitates reliable characterization of new magnetic materials in laboratory settings.
- Product Certification: Provides the basis for attesting that materials comply with industry requirements for transformers, motors, and generators.
- Industrial Testing Laboratories: Ensures uniformity and reproducibility in independent testing facilities through standardized measurement practices.
- Modernization of Testing: Incorporates digital sampling and data acquisition, supporting advanced automation in analysis and reducing human error.
Related Standards
The standard references and aligns with several other key documents and standards in the field of magnetic materials, including:
- IEC 60050-221: International Electrotechnical Vocabulary - Magnetic materials and components.
- IEC 60404-4: Methods of measurement of d.c. magnetic properties of magnetically soft materials.
- IEC 60404-8-3/8-4/8-7: Specifications for electrical steel sheet and strip in various states (semi-processed, fully-processed, non-oriented, and grain-oriented).
- IEC 60404-10: Methods for measuring magnetic properties of magnetic sheet and strip at medium frequencies.
- IEC 60404-13: Methods of measurement for density, resistivity, and stacking factor of electrical steel sheet and strip.
Practical Value
By specifying uniform test methods for the measurement of magnetic properties such as specific loss and magnetic polarization, SIST EN 60404-2:2002/A1:2008 safeguards product quality in the manufacturing of key components for transformers, electrical motors, and other devices relying on magnetic steels. The integration of digital sampling techniques reflects current industry direction, enhancing test precision and making the standard highly relevant for automated and modernized quality assurance environments.
