Which standard includes the requirements for door closing speed and gasket clearance?

• A. NSTM 600
• B. NSTM 233
• C. NSTM 231
• D. NSTM 503

Answer: (A)

Understanding how doors perform on a ship is all about ensuring a reliable seal without creating hazards. The requirements for how fast a door should close and how much clearance the gasket needs are part of the standards that govern door performance and sealing. The standard that covers these door characteristics is NSTM 600, which addresses general shipboard mechanical equipment and its operating criteria, including how doors close and how their seals are configured. Adhering to these specs helps ensure watertight or airtight integrity is maintained during normal operation and emergency conditions, preventing unwanted leakage and reducing the risk of injury from door movement. The other standards deal with different systems and do not lay out door closing speed or gasket clearance requirements, so they don’t apply here.
