Overview
EN 12384:1999 - published by CEN - defines standardized test methods for assessing the elastic behavior of thin copper and copper-alloy strips. The standard covers determination of the modulus of elasticity (E) and the spring bending limit (O_fb) for strip thicknesses from 0.05 mm up to and including 1.0 mm. EN 12384:1999 applies specifically to strip types referenced in EN 1654 and is intended for use in material characterization, quality control and specification compliance.
Key topics and requirements
- Scope and applicability: Applies to copper and copper-alloy strips within the stated thickness range; intended for strip types specified in EN 1654.
- Test methods: Standardized procedures to measure the modulus of elasticity (E) and the spring bending limit (O_fb) of strip specimens.
- Specimen handling and preparation: Requirements for sampling, specimen dimensions and conditioning to ensure reproducible results (as defined in the standard).
- Test apparatus and setup: Description of the mechanical equipment and fixtures required to perform bending and elasticity measurements consistently.
- Calculation and interpretation: Procedures for deriving modulus of elasticity and spring bending limit from measured data and for reporting results.
- Reporting and documentation: Minimum information to be recorded and reported to demonstrate compliance and facilitate comparison (test conditions, material ID, thickness, test results).
Practical applications
EN 12384:1999 is useful for:
- Manufacturers of copper products - to control production quality of strips used where elastic behavior is critical (springs, connectors, flexible conductors).
- Testing laboratories - for standardized testing and certification of copper strip mechanical properties.
- Design and R&D engineers - to select appropriate copper alloys and strip thicknesses based on verified modulus and bending limits.
- Procurement and quality assurance teams - to specify acceptance criteria in contracts and verify supplier compliance.
- Regulatory and conformity assessment - to demonstrate that material properties meet industry or customer requirements.
Related standards
- EN 1654 - referenced for strip specification and applicability.
- Other CEN/ISO standards on copper products and mechanical testing may be relevant for complementary test methods and material specifications.
