Edge Crush Tester or ECT is one of the two predominant methods, primarily used to test the strength of a corrugated sheet. Manufactured by Testronix Instruments, the crush tester is used to exactly tell you how much weight will take to actually crush the box which is made up of a corrugated sheet. This testing machine determines the edge test of the corrugated sheet to test how much weight will crush it down by applying the weight to the edge of the sheet.  

The instrument measures the cross-section crushing of corrugated cardboard to determine the ability of a sheet of corrugated cardboard to resist crushing forces. The greater the resistance, the stronger is the sheet. Once you arrange your corrugated sheet onto the tester, you measure the bursting strength in kilograms per square centimeter, which will give you the bursting factor as a thousand times the bursting strength. This will be then divided by the grammage of the board that is being tested by the crush tester. Testronix Instruments Edge Crush Tester gets manufactured under Test Standard IS 7063.

Why use crush tester?

The testing instrument has usability features that gives it an edge over other similar testing tools available in the market. It also features as Ring Crush, Edge Crush, or even a Flat Crush Strength tester that measures the rigidity corrugated sheet, edgewise. Other features include:

  • Microprocessor-based display for accurate testing results
  • Display for compression strength of test sample
  • Separate fixtures provided for ring crush, edge crush and flat crush test.
  • Highly accurate test results taken under a compression force
  • Strong gripping clamps that hold tight
  • Bright LED display makes easy readability
  • Inbuilt calibration facility provided
  • Feather touch controls are a boon to be working with

The edge crush tester comes in two models as manufactured by Testronix Testing Instruments. This depends on the usability of the customers too, which one do they need as per the requirements. The first is the Computerised model and the second is the Digital model with printer facility. This gives a ready chance for taking hard prints of the testing displays for future references.
