Edge Crush Tester (Digital Model) brings hi-end features and technology to test packaging box raw material like corrugated or non-corrugated cardboard sheets.The tester evaluates how resistant a cardboard edge is against a vertical crushing load. It can analyze the strength and sturdiness of cardboard sheets by performing Edge Crush Test (ECT).

The edge crush test measures the compressive force a cardboard material can sustain in its vertical or loading direction before collapsing. A finished box's compression strength is defined by the amount of force needed to crush a section of cardboard when standing on its edge.

Resistance to vertical load. Test method). Have a question or want to make an enquiry? Our glass experts would be happy to help.

For the uniaxial or unconfined compressive strength test a right circular cylinder of the material is compressed between the platens of a testing machine as illustrated in Fig. 8.1. The compressive strength is then defined as the maximum load applied to crush the specimen divided by the cross-sectional area.

Similar to type a, but with no well-formed cones. • Crushing (g): Occurs in the top ¼ of the cylinder. Indicative of defective cylinder. E. Standard 28-day Strength Cylinders (Sets of 3):

• The Edge Crush Test of combined board is dependent on the cross direction ring crush/Short Colum Test of the various paper components. This includes the quality of the fluting process and the bonding between the components. • Structurally speaking, the strongest board combinations balance the vertical

Edge Crush Test(ECT) The Edge Crush Test tells us the weight that can be stacked up on the packing box per square inch before the box breaks. How ECT Works The corrugated paper board specimen is loaded vertically into the machine. The vertical pressure plate slowly applies the weigh on the specimen.

The average crushing strength of the control samples (with no coatings) was 60.5 kN. The graph in Fig. 18 indicates that values of the crushing strength for samples A-1 to 3 (both individual and average values) are apparently higher than for samples C-1 to 3 and E-1 to 3. This allows us to conclude that crushing strengths of the rings coated on ...

ECT - Edge Crush Test BP- Box Perimeter Overhang Factor =1 – [minimum of (square root of Overhang) × 32.25 ÷ 100, 1] HFF-Horizontal Flute Factor = 1 unless non-vertical flute is selected. If non-vertical flute selected, TOPS Pro looks at HFF for the specific board grade. However, there is no generally accepted industry standard for how

definition in any way that might influence the roof strength (e.g., a vehicle with a sunroof would not be tested if the typically equipped vehicle lacks this option). Once the test vehicle has been acquired, either the driver or passenger side of the vehicle is selected for testing. For most vehicles, the test side is chosen at random.

sliding shear failure, toe crushing failure, and diagonal tension failure. These behavior modes are affected by the compressive strength of masonry unit, aspect ratio, and vertical axial stress. From the behavior mode, strength acceptance criteria …

The vertical pressure plate slowly applies the weigh on the specimen. The test completes and gives you the ECT measurement before the edge crushes. Flat Crush Test (FCT) The Flat Crush Test tells us the resistance the box will present to the external force. It measures the resistance of corrugated paperboard to flute Crushing.

Strength of pipes: The crushing strength of sewer pipes is determined by the three-edge bearing test. The pipe is stressed until failure occurs. Table (3) gives the minimum crushing strength for clay pipes. Strength requirements for reinforced concrete pipes are given in table 4, for this table the crushing force correspond to 0.25mm crack.

There are mainly two methods to test the corrugated printed box strength. One is the Mullen test, the other is the Edge Crush Test. Mullen Burst Test. The Mullen Burst Test measures the force required to puncture the face of corrugated board and is reported in pounds per square inch (psi), boards are thus rated accordingly eg #275.

Rebound Hammer Test is a Non-Destructive Test method widely used to measure the quality, uniformity & compressive strength of the concrete.

The second series involved the test of five deep beams without transverse reinforcements. In both series, vertical pre-cracks were created in the shear span of the specimens by means of reversed flexural loading. Then, the beams were loaded in shear to fail by web crushing. The width of pre-existing cracks was a main parameter in the test.
