Typical scenarios within this site’s subject: questions to ask, materials to prepare and points that can be examined.
Typical scenarios
If a portable device’s packaging says IPX4 but the seller promises operation after immersion, separate those claims. Splash protection and immersion testing concern different exposures. Preserve casing markings, closure positions and the exact seller description before testing.
Typical scenarios
If a marking report compares closed-bottle weight with declared net mass, establish whether packaging was deducted. Bottle, cap and dispenser weights may vary within a delivery. Distinguish product mass, tare and volume where the manufacturer declares volume.
Typical scenarios
If a box code scans before wrapping but not afterwards, preserve both conditions. A checkout scanner’s failure does not establish number alteration or product origin. Folds, seam location, reflections and clear space around the printed symbol matter on the actual pack.
Typical scenarios
If traces of another impression appear beside a batch code, later alteration may be suspected. Examine the label with its packaging rather than a cleaned fragment: overlapping inks, surface damage and adhesive placement can provide different evidence about the order of operations.
Typical scenarios
Suppose a repaired item has a new information plate and traces of an earlier attachment. Replacement alone is used to argue that identifying information changed, although the old plate’s contents are unknown.
Typical scenarios
If a receipt record gives one serial number while a photograph suggests a different character, the discrepancy does not itself establish altered marking. Transcription error, viewpoint, glare, dirt or different copy quality can produce different readings. Each record and photograph must be connected to the particular item.
