Shock o Purposes: 1. probable drop height a given package should be designed to withstand 2. being the basis of preshipment test procedures and 3. provide information for the development of protective packaging systems e fundamental lessons are as follows The probability that a package will be dropped from a height greater than 1 meter(40 inches)is minimal
Shock ⚫ Purposes: 1.probable drop height a given package should be designed to withstand. 2. being the basis of preshipment test procedures and 3. provide information for the development of protective packaging systems. ⚫ Fundamental lessons are as follows: The probability that a package will be dropped from a height greater than 1 meter (40 inches) is minimal
Shock Packages receive many drops from low heights, while few receive more than one drop from greater heights Skidded, wrapped, or otherwise unitized loads are subject to fewer drops than individual packages There is little control over drop orientation with small packages. With larger packages, about half of the drops are on the base a heavier package has a lower probable drop height

Shock The larger or bulkier the package, the lower the probable drop height Handholds reduce the probable drop height by lowering the container relative to the floor Cautionary labeling (fragile, this side up, handle with care) has only a minor effect. Cautionary labeling is no substitute for sound packaging practice Address labels tend to orient the drop to a label- up position regardless of other instructions

Shock The usual results of drops and shocks fall into two categories protective or containment qualities are reduced bending, distortion, or, ultimately, breakage Shock During Rail Transport: Railcar coupling: boxcars assembled into trains by moving individual cars, The average shunting speed is 8. 4 kilometres per hour. This is the average speed; some of the impacts are at greater speeds! (Figure 12.3)
