BS EN 2667-2 is the second part of a multi-series standard covering a test method for foaming structural adhesives that enables superior structural joint strength in aerospace applications.
BS EN 2667-2 defines the test method for determining the bond strength of structural foaming adhesive films or pastes by means of the tube test method.
BS EN 2667-2 test method is suitable for determining bond strength in relation to the density after curing of the adhesive foam by means of compressive tube shear specimens. BS EN 2667-2 applies to high expansion ratios, i.e. > 50 % measured according to the method EN 2667-3.
BS EN 2667-2 on test method for foaming structural adhesives applies to:
Foaming adhesives are modified epoxy substances in sheet form and are applied using either restrained foaming or free foaming techniques. They reduce the amount of variation in cell structure caused by process variables like changes in temperatures. They are used in structural aerospace applications, which increases bond strength in joints.
BS EN 2667-2 provides you guidance on apparatus, auxiliary equipment, test tubes, test specimens, procedure, expression of results, designation and test report that ensures the accuracy of the results.
BS EN 2667-2 provides you guidance on the compressive tube shear specimen test method to determine the bond strength of structural foaming adhesives. BS EN 2667-2 also provides you with a step-by-step procedure for the technique that enables you to do the method correctly.
Guidance in BS EN 2667-2 enables you to develop and assess foaming structural adhesives for non-metallic materials, enhancing sealing properties, superior structural joint strength and stress distribution in aerospace applications.
