looking for an IOPP study that was published long time ago (could be in 1990s).  It talks about the probability of a package exposed to various transit stress (drop or vibration) in relation to the package weight. 

Sarah,

Unfortunately, I don't see that report in our old files. You might consider IoPP's Transport Packaging book, which has many calculations related to shock, vibration and more. The Third Edition is in the IoPP bookstore.

Hello Sarah, 

Is this the study you are referring to, perhaps? It is not an IoPP study. Let me know if this works!

ABSTRACT

DROP HEIGHTS ENCOUNTERED IN THE UNITED PARCEL SERVICE

SMALL PARCEL ENVIRONMENT IN THE UNITED STATES

BY

Thomas Martin Voss

Packaged goods move through various logistical networks

each day all over the world. Packages moving through these

various networks are exposed to dynamic forces such as drops,

tosses, and kicks. This study investigated the effect of

drops, tosses and kicks encountered in the United Parcel

Service (UPS) small parcel environment in the United States.

The effect of the weight and volume of packages shipped was

studied.

The results of this study showed ‘the highest, drop

observed in the UPS environment in 35 roundtrips from Lansing,

MI to Monterey, CA was 42.1 inches for the Small size package.

The size of the package had no significant effect on the drop

heights" Lighter weight. packages for' the smaller size

experienced higher drop heights. Weight did not have a

significant effect on the Medium and Larger size package drop

heights. 95% of the drops occurred at 30 inches for the

Small/Light package, 24 inches for the Small/Medium package,

18 inches for the Medium/Light package, 24 inches for the

Medium/Medium packages, 26 inches for the Medium/Heavy

package, and 18 inches for the Large/Medium and Large/Heavy packages.

Hi Sarah, 

The copy that I have available is for my company's internal circulation only, so unfortunately I will not be able to share that with you. 

You might just need to have your institution register an account and pay for it.
