Flexure Tests on Glass

The increasingly higher demands of clients and architects are bringing us closer and closer to the limits of what is technically possible in the field of construction. Compared to steel construction, glass construction still has very few standards. Computer control is often not possible, making destructive testing necessary to test the structure and document it accordingly. ZwickRoell supplies fixtures to enable standardized tests to be performed, including 4-point flexure tests on construction glass according to EN 1288-3 or the double-ring flexure test on flat specimens according to DIN EN 1288-5. ZwickRoell also provides solutions for individual testing requirements.

Additional Standard-Compliant Tests on Glass

  • DIN EN 1288-2, October 2007: Glass in building: determining flexural strength of glass—Part 2: Double-ring flexure-test on flat specimens with large test surface areas (ISO/DIS 1288-2:2007); German version EN ISO 1288-2:2007
  • DIN EN 1288-3: Glass in building: determining flexural strength of glass—Part 3: Testing specimens supported at two points (four-point bending) (ISO/DIS 1288-3:2007); German version EN ISO 1288-3:2007
  • DIN EN 1288-5: Glass in building: determining flexural strength of glass—Part 5: Double-ring flexure-test on flat specimens with small test surface areas (ISO/DIS 1288-5:2007); German version EN ISO 1288-5
  • ISO 614: Shipbuilding and marine structures: toughened safety glass for rectangular windows and side scuttles; punch method of non-destructive strength testing (ISO 614:1989-09)

Testing Tiles

ZwickRoell developed this test fixture for determining the adhesive strength of plaster or adhesives on tiles (for example, according to EN 1348). Adhesion tests at an angle of 90° are possible, while several tiles can be bonded to the concrete slab simultaneously and pulled off one after the other through simple position changes. ZwickRoell provides other solutions for tests on tiles, such as the 3-point flexure test according to EN 12002 and determination of shear strength according to EN 12003.

Flexure Tests on Roof Tiles

ZwickRoell's special 3-point flexure test kit enables tests to determine the flexural strength of clay roofing tiles (clay roofing tiles for discontinuous laying as per EN 538). Concrete roofing tiles and fittings can also be tested for flexural strength (as per EN 491).
