Aerospace series - Metallic materials - Test methods - Part 16: Non-destructive testing - Penetrant testing

This document outlines a specific procedure for non-destructive testing within the aviation sector, focusing on the examination of metallic materials. It addresses the methodology known as penetrant testing, which is designed to detect surface-breaking flaws in components. The approach is part of a broader series dedicated to test methods for aerospace metals, ensuring consistency and reliability in quality assurance processes. This technical specification details the steps, equipment requirements, and evaluation criteria necessary for conducting such inspections effectively. It establishes a uniform framework that facilitates the identification of cracks, porosity, and other discontinuities on the exterior of parts. By adhering to these guidelines, manufacturers and maintenance facilities can assess the integrity of aircraft components without causing damage. The content covers preparation of the test surface, application of penetrant materials, removal processes, and the development of indications. This standardized method supports the maintenance of high safety standards in the aviation industry by providing a clear protocol for detecting potential defects that could compromise structural performance.
