EN 2591-319:1997

Overview

EN 2591-319:1997 is a crucial standard within the aerospace sector, published by CEN, focusing on the integrity of electrical and optical connections used in aerospace applications. Specifically, this standard details the test methods for assessing the gastightness of solderless wrapped connections-a key factor in ensuring reliable and durable connectivity in harsh aerospace environments. It complements the broader EN 2591 series, providing a targeted approach to evaluating the sealing performance of these specialized electrical connections.

Key Topics

• Gastightness Testing: EN 2591-319 outlines precise procedures to verify that solderless wrapped connections prevent gas ingress, which is critical in maintaining electrical performance and preventing corrosion.
• Solderless Wrapped Connections: Focuses on connections made without solder, using a wrapping technique that must be tested for airtight sealing properties.
• Aerospace Electrical Standards: Part of the wider EN 2591 series, which covers electrical and optical connection elements and their testing methods.
• Testing Methodology: Provides a standardized testing approach that can be reliably repeated across different components and systems to ensure quality and safety.
• Compatibility: This standard is intended to be used in conjunction with EN 2591 general specifications for aerospace connection elements.

Applications

• Aerospace Electrical Systems: Ensures the reliability of wiring harnesses, connectors, and other electrical assemblies used in aircraft and spacecraft.
• Harsh Environment Protection: Relevant for electrical connections exposed to extreme pressures, temperatures, and potentially corrosive gases, typical in aerospace settings.
• Manufacturing Quality Control: Used by manufacturers and quality assurance teams to certify solderless wrapped connections before deployment.
• Maintenance and Inspection: Facilitates the verification process during routine maintenance, ensuring long-term gastight integrity and safety of existing aerospace electrical systems.
• Aerospace Design and Development: Assists engineers in selecting and qualifying connection techniques that meet stringent aerospace reliability and safety criteria.
