Overview

EN 2155-2:1993 is a CEN aerospace test-method standard that defines how to determine water absorption of transparent materials used for aircraft glazing. The method is based on immersion testing in conformance with ISO 62, method 1, but it adds the specific conditions and requirements relevant to aircraft glazing. The standard helps manufacturers, test laboratories and certification bodies assess how glazing materials absorb moisture-a key factor in optical performance, durability and airworthiness.

Key Topics

• Scope and applicability
  • Applies to transparent materials intended for aircraft windows, canopies and other glazing components.
  • Specifies immersion-based determination of water uptake following ISO 62 principles, adapted for aerospace use.
• Test principle
  • Measurement of mass change caused by water uptake after immersion, using defined specimen preparation and handling practices (specific procedural details follow ISO 62 and the aircraft glazing adaptations in EN 2155-2).
• Aircraft-specific conditions
  • Adjustments or additional requirements to account for aerospace environmental and safety concerns (e.g., conditioning, specimen selection, and reporting tailored to glazing materials).
• Reporting and conformity
  • Prescribes the type of results and data to record so findings can be used for material qualification, quality control and compliance demonstration.

Applications

• Material qualification - Validate new transparent polymers, laminates and coated glazing materials for aerospace use by quantifying moisture uptake.
• Quality control - Routine batch testing by manufacturers to ensure consistent material behaviour with respect to water absorption.
• Design and reliability analysis - Engineers use water absorption data to predict dimensional changes, optical distortion, adhesive performance and long‑term durability under humid or immersion conditions.
• Certification and regulatory compliance - Test laboratories and certification bodies reference EN 2155-2 when assessing glazing materials for airworthiness and environmental resistance.

Who uses it: aerospace materials engineers, glazing manufacturers, test laboratories, quality managers, regulatory authorities and researchers working on transparent aerospace components.

Related Standards

• ISO 62 - International method for determining water absorption of plastics; EN 2155-2 adapts ISO 62 (method 1) for aircraft glazing.
• Other parts of the EN 2155 aerospace series and general aerospace material test standards addressing mechanical, optical and environmental performance of transparent materials.
