The drop test lies, and everyone knows it

ISTA and ASTM transit tests are useful and they are not your supply chain. They model a generic journey: a fixed number of drops from fixed heights, a standard vibration profile, a conditioning cycle chosen for reproducibility rather than realism.

Your product goes on a specific route. It sits on a specific dock, in a specific season, handled by people with a specific set of incentives.

What we changed

We started shipping instrumented dummy units on the client's real route — accelerometers and temperature loggers in a case that looks like the product. Three shipments, one per season, and the data is not close to the standard profile.

The most common surprise is not impact. It is sustained compression at temperature: a pallet sitting in a yard at 34°C for eleven hours does more damage to fibre-based trays than any drop.

Why it is cheaper than it sounds

An instrumented run costs about the same as two rounds of lab testing, and it usually replaces four — because it tells you which tests are worth running at all instead of running every test at every level.
