Overview
EN 2591-502:2001 is a CEN/AECMA aerospace test method standard that defines a procedure to verify that an oversize test pin cannot enter a restricted-entry female contact used in elements of electrical and optical connection. The standard is intended to be used in conjunction with EN 2591-100 (General test methods) and supports verification, quality control and design validation activities for aerospace connector assemblies.
Key Topics
- Scope: Specifies a method to confirm that an oversize test pin cannot be inserted into a restricted-entry female contact. Applies to electrical and optical connection elements.
- Specimen preparation: Specimens shall be prepared according to the technical specification. Unless otherwise stated, the technical specification must define:
- the test pin definition per contact size;
- the number of specimens to be tested;
- the acceptance requirement.
- Procedure: A specified test pin is presented along the female contact axis to simulate insertion; the test verifies that the oversize pin is not capable of entering the restricted-entry contact.
- Requirement: The test pin shall not be capable of entering the female contact.
Applications
EN 2591-502:2001 has practical value across design, production and maintenance activities in the aerospace sector. Typical applications include:
- Connector design verification: Confirms restricted-entry features prevent incorrect or oversize probe entry during design qualification.
- Manufacturing quality control: Provides a repeatable acceptance check to ensure production parts meet restricted-entry requirements.
- Supplier compliance: Used by procurement and engineering teams to verify supplier components conform to specified restricted-entry behaviour.
- Maintenance and inspection: Helps maintenance organizations confirm that installed connectors retain restricted-entry characteristics after service.
Benefits of applying this standard include improved safety by reducing the risk of unintended contact engagement, enhanced interchangeability between components, and clear, auditable test procedures for compliance.
Related Standards
- EN 2591-100 - Aerospace series: Elements of electrical and optical connection - Test methods - Part 100 (General). This standard provides the general preparation and test method framework that EN 2591-502:2001 references and must be used together with it.
- Other AECMA/CEN aerospace connector standards may be referenced in the technical specification for detailed connector dimensions and test-pin definitions.
For implementation, ensure the technical specification for the connector documents the test-pin definition, specimen quantity and acceptance criteria before performing the restricted-entry verification as defined in EN 2591-502:2001.
