Rationale: AMS5557K is the result of a Five-Year Review and update of the specification. The revision prohibits unauthorized exceptions (3.7, 4.4.5, 5.2.1, 8.4), updates composition testing and reporting (3.1, 3.1.1), updated condition and fabrication requirements (3.2, 3.3), controls tensile testing (3.4.1.1), updates Table 2 adding additional size and footnotes, revises hydrostatic testing consistent with other tubing specifications (3.4.3), updates inspection (3.5), adds NDT acceptance testing (4.2.1, 4.4.3), clarifies tolerances and identification (3.6, 5.2), and allows prior revisions (8.3).
