Insulation is not the only explanation for moisture. Compare product start, package venting and load layout.
Separate the product event. Record lot, starting condition, package type, vents, position and receipt observation. Refer to the product specification.
Four event fields
- Product lot
- Package venting
- Position in container
- Moisture at receipt
If moisture recurs, first compare lot and packaging data; do not assume a universal relative-humidity target.
