ASTM D1623B Test Fixture | GD1623B-113

GD1623B-113 test fixture meets ASTM D1623B requirements. Each half of the GD1623B-113 fixture incorporates a dual yoke to ensure pure axial load is applied. The fixture is available in three sizes (25 mm, 50 mm and 75 mm square) to fit varying specimen geometries. Each fixture can be supplied with multiple sets of bonding faces to facilitate testing to ASTM D1623.

This sandwich flatwise tension fixture measures the bond strength between the facing and core of a sandwich construction panel. If the bond strength is sufficiently strong then the strength of the core itself can be determined. The specimen is subjected to tensile loading, normal to the bond facing, and applied through thick loading blocks included with the fixture.
