EN 4106:2013 (E) 5 1 Scope This European Standard defines the requirements for manufacture, qualification, inspection and testing of products in structural adhesive systems where the adhesive is supplied in the form of a paste, either a one-part or two-part system, for aerospace applications. The adhesive may be used in conjunction with a primer whose requirements are also included in this European Standard. It is applicable whenever referenced on a material standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
