Overview
EN 60404-4:1997/A2:2008 (based on IEC 60404-4:1995/A2:2008) specifies standardized methods for measuring d.c. magnetic properties of magnetically soft materials. This CLC/CENELEC amendment updates measurement and test-specimen provisions used across Europe to ensure repeatable, comparable results for materials such as electrical steels, soft magnetic alloys and laminated cores.
Key Topics
- Scope and purpose: Standardizes test procedures for direct‑current (d.c.) magnetic characterization of magnetically soft materials used in electrical and electronic components.
- Test specimen requirements: Clarifies acceptable specimen geometry and dimensions to reduce radial variation of the magnetic field in ring or toroidal samples.
- Outer/inner diameter ratio: Shall be no greater than 1.4, preferably less than 1.25, to limit radial field non‑uniformity.
- Cross‑sectional area guideline: The amendment states the usual cross‑sectional area range and provides a method to calculate area for stacks or wound cores.
- Cross‑section calculation: For stacks of laminations or toroidal cores, the cross‑sectional area A can be calculated from specimen mass (m), material density (ρ) and outer (D) and inner (d) diameters using the equation provided in the amendment:
- A (in m²) is calculated from m (kg), ρ (kg·m⁻³), D and d (m).
- Measurement accuracy considerations: The amendment addresses geometric influences on field uniformity and prescribes dimensional rules to improve measurement repeatability.
Applications
This standard is directly applicable to:
- Material manufacturers validating magnetic properties of soft magnetic alloys and electrical steels.
- Test laboratories and QA teams performing routine or acceptance testing of cores and laminations.
- Design engineers working on transformers, inductors, motors, magnetic sensors and other electromagnetic devices where d.c. magnetization characteristics affect performance.
- R&D groups developing new soft magnetic materials or evaluating heat‑treatment and processing effects.
Using EN 60404-4:1997/A2:2008 helps ensure that d.c. magnetic property data (coercivity, remanence, permeability under d.c. bias, etc.) are reliable and comparable between suppliers and laboratories.
