Overview
EN 2591-425:2001 is a European aerospace test method that specifies how to assess the unwrapping capability of solderless wrapped connections used in electrical and optical connection elements. Intended as part of the aerospace series of standards, it is used together with EN 2591-100 (general test method requirements) and aligns with AECMA/CEN procedures for connector testing. The standard defines specimen preparation, test apparatus, and the unwrapping procedure together with the acceptance criterion for conductor integrity.
Key Topics and Requirements
- Scope: Method for assessing the ability to unwrap solderless wrapped (wire-wrap) connections without damage.
- Specimen preparation: Specimens must be examined per EN 2591-101 (visual examination) and EN 2591-102 (dimensions and mass) and prepared as specified.
- Documentation required: Unless otherwise specified, records must state:
- Type of conductor or cable
- Type of contact
- Wrapping tool and unwrapping tool
- Type of wrapping (single or double)
- Test requirement/acceptance criteria
- Apparatus: The standard includes guidance on an unwrapping tool (figure example shows an approximate 12 mm dimension). The apparatus must not introduce additional twist or stress to the specimen during unwrapping.
- Procedure: Unwrap using the specified unwrapping tool while ensuring no additional mechanical stress is applied to the conductor.
- Acceptance criterion: Following EN 2591-101, no breaking or cracking of the conductor is allowed after unwrapping.
Practical Applications
- Ensures reliability of solderless wrapped connections in aerospace electrical and optical systems.
- Used by:
- Aerospace manufacturers and component designers to validate connector designs.
- Qualification and test laboratories performing acceptance and maintenance testing.
- Quality assurance and inspection teams responsible for supplier control and product certification.
- Maintenance organizations assessing the serviceability of wrapped connections during repair or inspection.
- Helps prevent in-service failures by verifying that wrapped connections can be safely unwrapped for inspection, repair, or rework without degrading conductor integrity.
