Quality Acceptance Standard (Yard)

A yard quality acceptance standard is the shipbuilder’s documented set of accept/reject limits for fabrication and welding, the misalignment, distortion, weld profile, and dimensional tolerances that decide whether a part is accepted, repaired, or rejected. Most yard standards are built on IACS Recommendation No. 47 (Shipbuilding and Repair Quality Standard for New Construction), which tabulates standard and limit ranges; deviations inside the standard range pass, beyond the limit range fail, and the band between is dealt with by agreed repair. The standard is approved by the attending classification society and governs the surveyor’s hold points. It ties the abstract class rules to a measurable acceptance criterion on the shop floor.
