  "standing": "A compilation from the published convention text, not a legal instrument. Flag administrations, class societies and company SMS procedures frequently impose shorter intervals, and convention text is amended — verify against the current text and the vessel's own certificates before relying on a row. The rows have not been independently verified against the instruments by a third party; corrections are welcome. Corrections: on 3 Sep 2026 three rows were corrected against secondary sources (a published transcription of the ISPS Code text, a P&I club's guidance quoting MARPOL Annex VI, and a class society's CIC guidance), not against the instruments themselves: security-drill (the 25% personnel-change trigger now carries the Code's qualifying clause), bdn (the MARPOL sample retention is a floor, not a period), emergency-generator (no convention test interval exists; the interval is set by the SMS under ISM Code 10).",
