49.025 - Materials for aerospace construction

This document provides a series of standard testing methods to determine the resistance of flat or curved surfaces against abrasion, scratch or punch under high dynamics as may occur for example by manually operating actuators or due to impacts of materials like shoes, cases, bags and other common objects of everyday’s usage inside an aircraft cabin. The method is also suitable to test the resistance of a surface against all other high dynamic strains.

This document specifies requirements and test methods for the qualification of laser beam machines
for metal powder bed additive manufacturing for aerospace applications.

This European standard specifies the characteristics of adjustable rod-ends consisting of:
- a spherical plain bearing, metal to metal, in corrosion resisting steel, wide series (EN 4265)
- a rod end with internal threaded shank
They are intended for use in fixed or moving parts of the aircraft structure and their control mechanisms
