Overview

EN 2591-514:2002 is a CEN/AECMA aerospace test method that specifies how to verify the solderability of contacts with self-contained solder and flux - i.e., contacts where the solder and flux are incorporated and are not accessible to a soldering iron. The standard defines specimen preparation, the heat-application procedure (using the component’s installation heat profile without inserting a cable) and the required visual assessment to confirm acceptable solder wetting.

Key Topics and Requirements

• Scope: Verifies solderability of contacts containing built‑in solder and flux that cannot be soldered directly by iron.
• Specimen condition: Test specimens must be tested “as supplied” in their original packaging.
• Test method: Apply heat according to the component’s installation procedure, with the exception that no cable is introduced into the contact during the test.
• Visual inspection: Assessment is made by visual examination in accordance with EN 2591-101 (naked eye or up to 4× magnification).
• Acceptance criterion: The solder must have wetted the contact area and form a relatively uniform, adherent film on the base material. If necessary, the contact may be carefully opened to inspect internal solder coverage.
• Normative reference: EN 2591-101 (visual examination method) is referenced and used for the inspection procedure.

Applications and Who Uses It

EN 2591-514 is targeted at organizations involved in aerospace electrical and optical connectors and their quality assurance:

• Aerospace component manufacturers - to qualify contact designs that use pre‑placed solder/flux and to validate assembly processes.
• Quality/inspection engineers and test laboratories - for routine acceptance, incoming inspection and supplier audits.
• Design and reliability engineers - to ensure connector designs meet solderability requirements when direct soldering is not possible.
• Procurement and regulatory teams - to define procurement specifications and compliance with aerospace connector test regimes.

This test method is particularly relevant for aerospace solderability testing, connector qualification, and ensuring robust electrical connections where conventional soldering access is restricted.
