General Information
Overview
EN 2155-3:1993 - "Aerospace series - Test methods for transparent materials for aircraft glazing - Part 3: Determination of refractive index" is a CEN standard that specifies the method for determining the refractive index of transparent materials used in aircraft glazing. This part of the EN 2155 series defines how to measure optical properties that affect visibility, optical distortion, and performance of cockpit and cabin glazing components.
Key Topics
- Scope and applicability: Applies to transparent materials intended for aircraft glazing, providing a standardized approach to refractive index measurement.
- Measurement principle: Establishes the accepted method for determining refractive index for aviation glazing materials (method details are defined in the standard).
- Specimen handling and preparation: Addresses preparation and handling requirements to ensure representative optical measurements.
- Reporting requirements: Specifies the information to be recorded and reported to ensure traceability and reproducibility of test results.
- Quality and compliance: Supports consistent optical characterization needed for material qualification and acceptance in aerospace applications.
(Note: this summary describes the topics covered by the standard; consult the full EN 2155-3 document for procedural specifics, tolerances, and instrument settings.)
Applications
EN 2155-3 is used wherever reliable refractive index data for aircraft glazing materials is required:
- Aircraft glazing manufacturers - for material specification, quality control, and production validation.
- Material suppliers - to certify optical properties of plastics, glass, or laminated glazing materials intended for aviation use.
- Test laboratories - to perform standardized refractive index testing and issue comparable test reports.
- Aerospace engineers and designers - to evaluate optical performance (visibility, distortion, glare) during material selection and product design.
- Regulatory and certification bodies - to verify compliance with aerospace optical requirements and support airworthiness assessments.
Benefits
- Ensures consistent, repeatable refractive index measurements across suppliers and laboratories.
- Enhances optical quality control, helping reduce visibility-related safety risks.
- Facilitates material comparison, procurement, and certification in the aerospace supply chain.
Related Standards
- EN 2155 series (other parts) - test methods for transparent materials for aircraft glazing (see full series for mechanical, optical and environmental tests).
- National implementations/adoptions (e.g., SIST EN 2155-3) reflect CEN adoption in specific countries.
