BS EN 2155-8:1989 is a European Standard that provides specifications for test methods used to determine optical distortion in transparent materials intended for aircraft glazing applications. Optical distortion refers to any deviation from the true image caused by irregularities or imperfections in the material, such as waviness, surface defects, or variations in refractive index.
The standard likely outlines procedures and methodologies for conducting tests to quantify optical distortion in transparent materials. This may involve the use of specialized equipment and techniques to measure and analyze distortions in transmitted images or light patterns passing through the material.
By following the methods specified in BS EN 2155-8:1989, manufacturers and quality control personnel can assess the optical quality of transparent materials and ensure that they meet the necessary standards for use in aircraft glazing. Minimizing optical distortion is essential for maintaining clear visibility and accurate perception for pilots and crew members, thus contributing to overall aviation safety.
