Product Datasheet

General product description

Test rig and accessories for tension and compression testing for single-plane safety glass or ship/marine glass.

The test rig is made of a solid coated metal frame. A hydraulic servo axis is installed in the center. Those raises controlled force loads to the specimen. The compressing indenter attachment and the bearing are made of an Ø 50 mm steel shaft, coated with rubber, and inserted in high performance slide bearings.

G: Glass (single-pane and toughened safety glass)
SG: Shipbuilding and marine structures
E: Welded corner and T-joint

The measurement occurs by a protected measuring system with a range of 500 mm that is installed protected in the hydraulic cylinder. A premium load cell and a carries frequency amplifier measure the force load.

The evaluation of the breaking load and the recording of the measured values in Excel format take place by the software. A comprehensive data evaluation about the optionally contained Excel-Macro is simply possible.

The surrounding and the operating staff are protected by a Plexiglas hood. Furthermore a security check against glass fragments is installed at the doors. A container catches the cullet below the test rig.


On request the following options can be offered:

  • Electro mechanic tension and compression test rig (like basic version however, load initialization via a servo regulated electro spindle and 20 kN premium load cell)
  • Bending strength of plate glasses (EN 1288-3; four point bending indenter and four point controlling bearing incl. rubber coating)
  • Determination of the strength of welded corners and t-joints (DIN ISO 614; compressing indenter and bearing, test gap: 5 mm, test width: 110 mm)
  • Attachment for testing of PVC and plastic corners (standard EN 514; base plate and indenter)
  • Testing of timber blanks and semi-finished profiles according to DIN EN 13307 standard (adjustable 4-point intender)
  • Adjustable 4-point bending indenter:
    • 4-point support
    • Max. length of test specimen: 1100 mm
    • Adjustable support and indenter
    • Rotatable support points
  • Excel analysis software for comfortable evaluation as well as continuous quality monitoring according to the standard
  • Individual coating in RAL colours

Note: Individual features, especially for your needs, can be provided after consulting.
