SIST EN 2591-210:2001

Overview

EN 2591-210:1998 (published by CEN) is part of the aerospace series for elements of electrical and optical connection. This Part 210 defines a test method for assessing the performance of mated elements of connection when subjected to an electrical overload current flowing across contacts for a limited period. The standard is intended to be used together with the general provisions of EN 2591 and provides a repeatable laboratory procedure to evaluate contact behavior under overload conditions.

Key topics and requirements

• Scope and purpose: Defines objectives and limits of the electrical overload test for mated connectors and contact elements in aerospace equipment.
• Test principle: Specifies that an overload current is applied across mated contacts for a defined, limited time to observe effects on electrical and mechanical performance.
• Performance assessment: Focuses on post-test evaluation of contact continuity, resistance changes, contact damage, insulation integrity and the ability of the mated elements to continue to meet performance requirements.
• Test setup and instrumentation: Requires controlled application of overload current and appropriate measurement of temperature, voltage, current and contact resistance during and after the test (see EN 2591 for general test environment and instrumentation guidance).
• Pass/fail criteria: Determines acceptable limits for degradation in contact resistance and mechanical integrity following overload; the specific acceptance limits and procedures are to be applied in conjunction with the EN 2591 series.
• Documentation and reporting: Calls for standardized recording of test conditions, observations and measured results to support qualification, procurement and quality assurance.

Applications

EN 2591-210 is used by organizations involved with aerospace electrical interconnection systems where safety and reliability under abnormal electrical conditions are critical. Typical users include:

• Aerospace connector and contact manufacturers performing design verification and production qualification
• Aerospace OEMs and systems integrators specifying connector performance for aircraft and spacecraft
• Independent test laboratories executing qualification and certification testing
• Maintenance and repair organizations assessing component fitness after electrical incidents
• Procurement and quality teams establishing supplier test requirements

Related standards

• EN 2591 (general test methods for elements of electrical and optical connection) - use together with Part 210
• CEN aerospace series standards for connectors and interconnect testing (refer to applicable parts for mechanical, environmental and electrical endurance tests)
