摘要

Gray iron castings (for example, castings that are required to be certified per 4-2-1/Table 1) are to be made at ABS-approved foundries where the manufacturer has demonstrated to the satisfaction of ABS that the necessary manufacturing and testing facilities are available and are supervised by qualified personnel.ABS approval is valid for 5 years subject to annual verification and/or endorsement by the attending Surveyor. The Surveyor is permitted at any time to monitor important aspects of casting production, including but not limited to mold preparation and chaplet positioning; pouring times and temperatures; mold breakout; repairs; heat treatment and inspection.
