SLR Document Changes: Error in Acceptance Criteria 1

Overview of purpose of change: Revise the last sentence of the acceptance criteria program element of GALL-SLR AMP XI.M33, Selective Leaching, to cite criterion (d) instead of criterion (c).

Basis Document Input: None required.

Document Changes:

SRP-SLR None GALL-SLR Revise GALL-SLR AMP XI.M33 as follows:

6. Acceptance Criteria: The acceptance criteria are: (a) for copper-based alloys, no noticeable change in color from the normal yellow color to the reddish copper color or green copper oxide; (b) for gray cast iron and ductile iron, the absence of a surface layer that can be easily removed by chipping or scraping or identified in the destructive examinations, (c) the presence of no more than a superficial layer of dealloying, as determined by removal of the dealloyed material by mechanical removal, and (d) the components meet system design requirements such as minimum wall thickness, when extended to the end of the subsequent period of extended operation. When evaluating a component in relation to criterion (cd) no credit is used for the material properties of the dealloyed portion of the component.
