Overview

EN 2591-604:2001 is a CEN/AECMA test-method standard that defines a procedure for assessing the cleaning capability of optical faces on unmated aerospace connectors after exposure to contaminants. It is intended to be used together with EN 2591-100 (general test method rules) and relies on insertion-loss measurement methods described in EN 2591-601. The standard helps determine whether specified cleaning methods and agents restore optical performance following contamination.

Key topics and requirements

• Scope: Specifies a method for assessing cleaning capability of optical faces of unmated connections exposed to contaminants.
• Preparation requirements: Test specimens must have specific details defined (unless given in a technical specification), including:
  • maximum allowable insertion loss
  • cleaning products and cleaning method
  • type and length of cable/fibre
  • fuels/lubricants selected from EN 2591-315
• Apparatus:
  • Light Launch System (LLS) and Light Detector System (LDS) as defined in EN 2591-100
  • vessels to contain contaminants and standardized cleaning agents
• Contaminants used (ambient temperature):
  • demineralized water
  • fuels
  • liquid lubricants
  • natural silica (grains 2.5–50 µm and 50–150 µm mixed 50/50 by volume)
  • mixture of water and silica (50/50 by volume)
  • liquid lubricants and silica (50/50 by volume)
• Test sequence (performed for each contaminant):
  1. measure initial insertion loss (per EN 2591-601)
  2. immerse the optical face in the contaminant
  3. clean the connection elements according to EN 2591-100
  4. mate the optical connection elements
  5. perform final insertion loss measurement (EN 2591-601)
• Outcome: Compliance is evaluated by comparing final insertion loss to the specified maximum insertion loss; the standard does not define numeric pass/fail thresholds (these are specified in the product technical specification).

Applications and users

• Aerospace manufacturers and suppliers validating optical connector cleaning procedures and maintenance instructions.
• Design and qualification engineers for optical/electrical connection systems in aircraft and spacecraft.
• Test laboratories and certification bodies performing contamination and cleaning-capability assessments.
• Maintenance and repair organizations establishing approved cleaning agents and methods for field service.
• Procurement and quality teams specifying acceptance criteria for optical connector performance after cleaning.
