A margin of safety would be nice.


I guess it was enough of a margin as there was no damage.

There is standard testing that is done for packaging and you can have it
tested for NSTA and UPS certification also. Most of it is overkill giving
a good safety margin. .

Some years ago a customer called me and said the packaging we provided
failed their new drop test. I went along with a designer from our company
and we met with his new QC guy and the president of the company that
originally bought the package from us.

The QC guy went on about the testing and the failure of the packaging in the
test and what the specifications and reasoning behind the testing was. .
After a lengthy diatribe, he was interrupted by President who asked two
questions:

Q. How many packages did we ship last year?

A. Over 50,000

Q. How many were damaged

A. None

President: Thank you for coming. The meeting is over and we will have no
need to re-assess our present packaging. It works.
