ASTM D5339-94(1998)

1.1 This practice establishes procedures for a quality assurance plan for structural steel fabrication for highway structures. These procedures pertain to the inspections, measurements, and tests necessary for the fabricator and owner to substantiate material and product conformance to contract requirements. The fabricator's quality control plan (QCP) is to be designed and implemented with the objective of ensuring that all materials incorporated into the work conform to contract requirements. The owners acceptance testing plan (ATP) is designed to provide assurance that the fabricator has successfully met this objective.

1.2 Inherent in this practice is the assumption that design details and specifications allow maximum flexibility in procedures and processes to allow the most cost-effective fabrication to be performed consistent with the quality level specified.

1.3 Alternative sampling methods, processes, procedures, and inspection equipment may be used by the fabricator when such procedures and equipment provide, as a minimum, the quality assurance required by the contract documents. Prior to applying such alternative procedures, the fabricator is to describe the procedure in a written proposal, and demonstrate to the satisfaction of the owner that the effectiveness of these alternative procedures are equal to or better than the contract requirements. In case of dispute, the procedures stipulated in the contract documents will apply.
