What is the Difference between Bursting Test Strength and Edge Crush Test? By viewing the 'Box Manufacturer's Certificate' (BMC) clearly printed on the bottom flaps, you will see the strength of the board, used to construct the box, as well as its size and weight limit. Also viewable in the seal is the Edge-Crush-Test or Burst-Test.
Corrugated Boxes – Edge Crush Test (ECT) There are currently two tests used throughout the corrugated industry to determine strength. Historically, the long time industry standard has been the Bursting (Mullen) Test, which is related to the rough handling durability of corrugated material.

The study examined that the linear relationship between Gross Domestic Product (Y_t) and Money Supply (X_t) from 1981 to 2014 is spurious and could be avoided by dynamic regression modeling.
An offset test is more demanding of a vehicle's structure than a full-width test, while a full-width test is more demanding of safety belts and airbags. In a full-width test, there is less crushing of the vehicle structure so the decelerations that these restraints must handle are greater.

Edge crush test (ECT) is a measurement of the edgewise-compressive strength of the corrugated board, expressed in pounds per inch. This property relates to the top-to-bottom compressive strength of corrugated shipping containers whereas burst strength relates more to containment properties. So what is the difference between burst and edge crush?

The crushing value should not be greater than 30%. The impact value should not be greater than 30%. The abrasion value should not be greater than 30% .
The difference between affect and effect is so slippery that people have started using "impact" as a verb instead. Don't be one of them! Another trick is to remember that affect comes first alphabetically, and an action (to affect) has to occur before you can have a result (an effect).
The impact crusher adopts the principle of impact crushing. After the material enters from the feed port, it is repeatedly crushed and broken between the hammer and the impact plate until it is discharged after molding.The cone crusher uses laminating crushing, and the rolling wall continuously moves toward the crushing wall, and the material sandwiched between the two is crushed.

Discrepancies between the left and right sides of vehicles spurred us to develop a passenger-side small overlap test and begin issuing passenger-side ratings in 2017. The passenger-side test is the same as the driver-side test except the vehicle overlaps the barrier on the right side.
Methods of test for aggregates for concrete3.81 Мб. With aggregate of ‘aggregate crushing value’ 30 or higher, the result may be anomalous, and in such cases the ‘ ten percent fines value’ should be determined instead.
Difference between Crushing and Grinding View Larger Image When making comparisons of the efficiencies of different grinding and crushing machines it is desirable to be able to estimate the work actually done in crushing the ore from a given size of feed to a given size of product, the screen analysis of both feed and product being determined.
The compressive strength of concrete is given in terms of the characteristic compressive strength of 150 mm size cubes tested at 28 days (fck). The characteristic strength is defined as the strength of the concrete below which not more than 5% of the test results are expected to fall.
Source ( Read full article at) :- Aggregate Crushing Value test. IMPACT TEST ON AGGREGATES: Aggregate Impact Value test determines the Aggregate Impact Value (AIV) of aggregates which provides a relative measure of the resistance of an aggregate to sudden shock or impact. Resistance of the aggregates to impact is termed as toughness.
