Use when a coverglass orientation scheme, coating-side marking or lot packaging convention has to be reviewed. Verify that the face of a delivered coverglass carrying the optical coating is identifiable under clause 8.3.3 of ECSS-E-ST-20-08C, so orientation survives the trip from tray to bond: decide whether an indicator may sit where it is declared at all, whether it still names a face once the piece is turned over, whether it survives the clean before bonding, what it costs inside the clear...

Use when a coverglass visual record has to support a delivery decision. Assess a coverglass inspection record against clause 8.7.1.3.6 of ECSS-E-ST-20-08C, which permits no cracking at all: sort every recorded indication into a crack family, a non-crack family or neither, reject the glass on any crack of the surface, an edge or a corner whatever its length, route a non-crack mark to the clause that does bound it, refer one nobody has named, and certify absence only where the record shows all ...

Use when a coverglass data package is about to go out with the glass. Audit the data package a coverglass delivery is released against under ECSS-E-ST-20-08C clause 8.9: name the qualification family nobody wrote up, catch a record citing an issue that no longer governs, hold anything still in draft at delivery, reconcile the delivered batches against the batch data files in both directions, check every file carries a measured row for each piece its batch delivered, and refuse a row reporting...
