What does ECT stand for in boxes
The Edge Crush Test, or ECT, is a newer test developed to look specifically at how much force a corrugated material can withstand on its edges without crushing. Instead of applying force to the face of the corrugated material, as the Mullen Burst Test does, ECT applies force to the edge.

40 Edge Crush Test (ECT): Great force, can hold a maximum load of 80 lbs, and over 40 lbs of pressure needed to rupture or be punctured.
How is ECT measured?
ECT is a measure of the edgewise compressive strength of corrugated board. It is measured by compressing a predefined section of board on its edge between two rigid platens. This compression is performed perpendicularly to the direction of the flutes until the board collapses and a peak load is reached.
What is board grade?
Board grade – A grade given to corrugated board based on three elements; firstly, the weight and type of outer liner, secondly the type of flute and thirdly the weight and type of inner liner.What is RCT paper?
The ring crush test (RCT) is used to determine the ring crush resistance of a paper strip formed into a ring with a standardized length and width.

What is a Mullen rated box?
To test the strength of the corrugated cardboard boxes, a hydraulic testing device (called a Mullen tester) applies pressure to a flat piece of suspended corrugated. It measures the force (in pounds per square inch) required to burst that board, sometimes referred to as “stacking strength.”

What is burst test?
A burst test is a destructive test and performed to determine the pressure overload capacity of pressure containing parts. The tests are performed with a fluid. … working pressure and the pressure when the product completely fails (burst pressure).
What is ECT and BCT?
The ECT (Edge Crush Test) and BCT (Box Crush Test) are two completely separate tests yet they are similar in various ways. The Edge Crush Test involves taking a 2 x 2 cardboard specimen and crushing the edge between compression platens with our lowest cost tabletop machine.
What is burst strength?
Burst strength is the amount of internal pressure a pipe can withstand before the pipe fails or bursts. … Trenchless rehabilitation methods such as sliplining, thermoformed pipe and pipe bursting can be used to rectify or replace burst pipes without the need to excavate.
How do you calculate compression strength of a box?
Let’s say there are six cartons stacked in a layer stack and each weighs 5.2Kg. Stack load = (6 – 1) X 5.2 = 26Kg of weight will be on the lowest carton. This box must be able to withstand this calculated test force, otherwise, the stack may collapse, the box may deform, and the product/s inside may be damaged.
What is meant by edge crush test?
An edge crush test (ECT) is a laboratory test method used to measure the cross-section crushing of corrugated cardboard. This offers the necessary information to determine the ability of a sheet of corrugated cardboard to resist crushing forces.

What is Cobb test?
The Cobb test determines the amount of water absorbed into the surface by a sized (non-bibulous) paper, paperboard, and corrugated fibreboard paper or paperboard sample in a set period of time, usually 60 or 180 seconds (Cobb60 or Cobb180). Water absorbency is quoted in g/m2.
What is RCT test in Kraft paper?
The ring crush test (RCT) is utilized to decide the ring smash opposition of a paper strip shaped into a ring with an institutionalized length and width. The ring crush test is like the limited capacity to focus test in that the quality of the liner or fluting is estimated both in the machine course and opposite to it.

What is a fol box?
The Full Overlap (FOL) box is a heavy-duty box for heavy-duty purposes. The flaps on this style extend all the way to the opposite side of the box when folded, completely overlapping each other. This adds stacking and structural strength to the box, making it ideal for storing or shipping heavy items.
What is a GREY board?
Grey Board (also known as chipboard) is a 100% recycled material that is formed by transforming recycled fibres and compressing them into a strong, flexible board. Grayboard has the characteristic ‘raw’ look that many recycled paper products have due to the fact that it’s made using recycled fibres.
How much weight can a corrugated box hold?
Cardboard box standards dictate how much weight a specific box can handle, so it depends on the box. But a standard 200# box measures 1.5 cubic feet and is built to hold up to 65 pounds, and the next level up (275#) can hold up to 95 pounds.
How much weight can a box carry?
If you need a box to hold more weight than the 20 to 80 pound range, keep in mind that you can opt for stronger, double-walled and triple-walled types of boxes. Double-walled boxes can typically hold between 60 and 150 pounds of items, while triple-walled boxes can hold up to 300 pounds in items.
