The inspection report on this batch came back with three defects on it. It still passed. Here's why that's the honest version.

510 slush makers, headed to Denmark. Before they shipped, a third-party inspector pulled 80 cartons

and went through them against an AQL plan — Level II, ISO 2859-1.

They found two surface scratches and one dent. Three minor defects across the sample.

The order passed.

That part trips people up, so it's worth explaining. An AQL inspection doesn't ask "is this batch perfect?" It asks, "Is the defect rate low enough that the batch is acceptable?" On this sample size, the plan allowed up to seven minor defects.

We had three. Zero major, zero critical.

I bring this up because "100% perfect" is the most common lie in this industry. No mass-production run of several hundred units is flawless. Anyone who tells a buyer otherwise is either not inspecting properly or not telling them what they found.

What actually matters are three things. Is someone independent checking? What's the threshold? And does the supplier show you the defects or hide them?

The rest of the report was the unglamorous stuff that keeps a product out of a recall notice — hi-pot at 1500V, earth continuity under 0.1 ohm, a four-hour load run, power cord pull test, all against IEC/EN 60335-1.

Those scratched units didn't ship, by the way. They came off before the cartons were sealed. That's the whole point of catching them.
