The Bursting Strength Test is a consistent, reliable and easy-to-use method to define or measure the bursting strength of a paper or paperboard. It is an important measure of quality because it gives an indication of how much pressure a material can resist before . See moreBursting strength is measured utilizing a rubber diaphragm that is expanded hydraulically against the paper sample. A bursting test is also known as a Mullen test [New Window] or pop test [New Window], and a minimum bursting strength is required for cartons used for shipping. Bursting strength has little application for printing papers.“ The .The burst test is frequently used as a general guide to the strength of paper, solid board and corrugated board. Bursting strength is usually quoted in kPa. We determine bursting strength using a digital hydraulic paper or digital .
If you are not clear with how to calculate Bursting Factor (BF) of paper, well this video is especially for you.#burstingfactor #burstingstrengthtester #burs.
The Mullen Test or Bursting Strength Test checks the toughness of the walls of the corrugated board when subjected to force or pressure. In this testing procedure, a rubber diaphragm is used to apply pressure to the walls of the corrugated box until it bursts. . As per the McKee formula: Compression Strength = 5.874 * ECT * CBT0.508 * P0.492 .The simplified McKee formula above provides a quick estimate that should not be used to rate the strength of an actual box. Such an estimate shall not to be used in place of testing conditioned test samples in a controlled, repeatable test environment, with calibrated instrumentation, validated machines, and trained test operators. The bursting factor indicates the material's strength and durability, particularly its resistance to bursting under pressure. How is the grammage of a material measured? The grammage is measured by weighing a standard area of the material, usually expressed in grams per square meter (g/m²).

Another test is carried out without a specimen. The pressure to do this is noted and then deducted from the earlier reading. (P1 - P 2) is the actual bursting strength of the specimen. Mean bursting strength “kN/m 2 ” Mean bursting distance “mm” Click on Image to run the animation Figure: A diaphragm bursting strength tester .Mill Test Pressure. The "Mill Test Pressure" refers to the hydrostatic (water) pressure applied to the pipe at the mill to assure the integrity of the pipe body and weld. P t = 2 S t t / d o (4) where. P t = test pressure (psig) S t = specified yield strength of material - often 60% of yield strength (psi) Wall ThicknessThe 2 Most Commonly Used Methods for Fabric Bursting Strength Test. They are the hydraulic and pneumatic methods. The hydraulic method has a wider range of applications and is capable of doing greater strength bursting tests. . Expansion strength is calculated according to the following formula: A=B-C. A – the average expansion strength of .Bursting Strength Tester is used in all paper and packaging industries to measure the strength of the boxes. To perform the test, the test specimen is placed between the two jaws of the instrument and uniform pressure is created throughout the material with the help of rubber diaphragm until the specimen burst. The structure of the paper .
Bursting Strength Tester Machine is specifically designed for measuring the bursting strength of paper and strong paperboard. The testing procedure involves preparing the specimen and securing it between two circular clamps. Using the geared handle provided, the specimen is tightened. The hydraulic pressure is incrementally applied by .
The HydroBurst Burst Strength Tester utilizes hydraulic bursting (diaphragm method) to determine the burst strength and expansion of knitted fabric, woven fabric, non-woven fabric, laminated fabric, elastic woven fabric, paper, and other materials when subjected to stress in both warp and weft directions, as well as in all other directions, to get the material’s burst strength. Bursting Strength is the pressure required to burst the material, measured using a Bursting Strength Tester. Grammage is the weight of the material per unit area, typically measured in grams per . The test method used is ASTM D3786: “Standard Test Method for Bursting Strength of Textile Fabrics—Diaphragm Bursting Strength Tester Method,” and it is also referenced in an ASTM test method for coated fabrics, ASTM D751. SOURCE ASTM Juli Case is ATA‘s information and technical services manager.

determining the strength of a box, the corrugated box industry uses two test, the Bursting (Mullen) Strength Test and the Edge Crush Test (ECT). The Bursting Test is reported in pounds and is related to the handling durability of the box material. It is measured and determined by the force required to puncture or rupture the actual corrugated box.The formula is named after Peter Barlow, an English mathematician. Equation: Where: P = Fluid Pressure (psi) T = Pipe Wall Thickness (in) O.D. = Pipe Outside Diameter (in) SF = Safety factor (General Calculations 1.5 10, Use 1 For Bursting Pressure) S = Material Strength (psi) Ultimate Tensile strength or Yield strength can be used.TAPPI T 807, Bursting strength of linerboard, Test Method [6] TAPPI T 810, Bursting strength of corrugated board, Test Method [7] TAPPI T 1200, Interlaboratory evaluation of test methods to determine TAPPI repeatability and reproducibility [8] Brauns O., Danielsson E., Jordansson L., Svensk Paperstidning 23 867 (1954) 1) [9]
