EN 2591-413:1998

Overview

EN 2591-413:1998 is a CEN aerospace series test method that specifies how to assess the holding force of grounding spring systems used in elements of electrical and optical connection. The part is intended to be used together with the wider EN 2591 series and has been adopted nationally (e.g., SIST EN 2591-413:2001). The standard supports consistent evaluation of grounding spring retention to help ensure connector integrity in aerospace applications.

Key Topics

• Scope and purpose: Defines the objective of measuring holding force for grounding springs within connector assemblies.
• Test method principle: Describes the approach for determining the mechanical holding capability of grounding spring systems (general method description; specific procedural details are contained in the standard text).
• Test setup and conditions: Outlines the necessary test environment and preparation in general terms to ensure repeatable assessment.
• Use with EN 2591 series: Specifies that this part complements other EN 2591 clauses covering elements of electrical and optical connection and their test methods.

Keywords: grounding spring, holding force, test methods, aerospace connectors, EN 2591, grounding reliability.

Applications

This standard is relevant for stakeholders involved with aerospace electrical and optical connectors where grounding performance matters. Typical applications and benefits include:

• Quality assurance and manufacturing inspection of connector grounding components.
• Design validation and comparative assessment of grounding spring retention characteristics.
• Supplier and procurement specifications ensuring consistent connector performance.
• Maintenance and component acceptance testing to support system safety and electromagnetic compatibility (EMC) considerations.

Adoption of the test method helps organizations demonstrate reliable grounding, reduce the risk of intermittent grounding faults, and support compliance with aerospace procurement and certification requirements.

Related Standards

• EN 2591 (series) - the parent series covering elements of electrical and optical connection and general test methods; EN 2591-413 is a specific part within this series.
• National adoptions such as SIST EN 2591-413:2001 reflect the standard's incorporation into local regulatory frameworks.
• Other CEN aerospace electrical standards and industry test methods that address connector performance, EMC and mechanical durability (refer to the respective documents for details).
