Inspection and repair decisions

A documented final evaluation comparing completed work with the baseline, approved test or mockup, and agreed acceptance criteria.

A qualified analysis of whether a glass lite or assembly satisfies stated load, support, safety, service, and condition requirements.

The lowest permitted remaining thickness established for a particular product, location, load, treatment, and decision authority.

A documented condition under which replacing the lite or assembly is the recommended or required action instead of surface restoration.

The measured or defensibly estimated glass thickness that remains at the thinnest part of a treated area after material removal.

A predefined observation or event that requires work to pause immediately until the condition is evaluated and authorization to continue is documented.

A defined condition that sends a glass assessment or treatment decision to a manufacturer, engineer, conservator, glazier, laboratory, safety specialist, or other qualified party.

A practical evaluation of whether a proposed restoration can meet the agreed outcome given glass type, damage, access, risk, time, cost, appearance, and alternatives.

The documented conditions a product or completed work must satisfy to be accepted for a stated purpose.

The technical possibility of improving or correcting a defined glass condition to agreed criteria without unacceptable harm.
