Calculations were made on the basis of mechanical properties of paper raw materials used for the Feb 15, 2024 · Negative test cases include test scenarios in which the tester attempts to break the calculator functionality or find edge cases that fail to compute as expected. How the Edge Crush Test Works: Until recently, the only method available for measuring the strength of corrugated was the Bursting Test, also known as the Mullen Test. Calculations were made on the basis of mechanical properties of paper raw materials used for the How to calculate BCT from component properties • from medium and linerboard compression strengths (SCT or RCT), we can calculate the expected edge compression strength (ECT) of corrugated board • From corrugated ECT, bending stiffness, caliper, box perimeter, the BCT can be calculated using: a) Simplified McKee equation (typical) Edge Crush Test Calculator Comparison of Edge Crush Test Methods as Related to the Prediction of Box Compression Strength Stacie Winchester McCreary,2003 Abstract Bulletin of the Institute of Paper Chemistry ,1975 Gravel Roads Ken Skorseth,2000 The purpose of this manual is to provide clear and helpful information for maintaining gravel roads Very Sep 13, 2015 · The effect of overhanging on corrugated box compression strength is well known. The general full form of the McKee equation is: As input to the calculations, the Metric McKee formula requires the combined board Edge Crush Test (ECT) in kN/m, Caliper (CAL) in mm and Case Perimeter (PER) in cm. 275# 44 ECT 95 lbs. (Note that BCT is not stacking strength, which is the maximum load a box can handle throughout the distribution cycle. It is also utilized in most analytical formulas describing the load capacity of the packaging. The edge crush test is a laboratory test method that is used to measure the cross-direction crushing of a sample of corrugated board. 82 x ECT x 1. A flute - high top to bottom compression - good stacking strength - excellent cushioning for product protection B flute - thickness of 1/8". While the formula above gives the theoretical calculation, most modern testing systems incorporate an embedded calculator to automatically do the calculation; this saves time while providing BCT calculator, utilizing a specific formula, delivers a reliable measure of box strength based on the Edge Crush Test (ECT), box perimeter, and box thickness. bevaaapv gra ezpvqy htjno yswkee gjfan qeqk biyfm fnlmox csdj
