Scope

Scope: This document specifies the terms and definitions, testing methods, general requirements, comparison specimens, testing procedures, testing records, and testing reports for impact testing of sandwich structures. This document is applicable to the in-service detection of delamination and damage between the skin and core in sandwich structures with titanium alloy and aluminum alloy metal skins, composite skins, and foam skins with a skin thickness not exceeding 2mm. The detection of skin delamination and repair quality in composite skins with honeycomb and foam cores can be carried out with reference to this document.
