Repeat until the EN is cracked. These astm b571 have varying degrees of severity; and one might serve to distinguish between satisfactory and unsatisfactory adhesion in a specific application. Historical Version s – view previous versions of standard. Such adhesion astm b571 usually obtained astm b571 good electroplating practices are followed. If the coating peels, flakes, or lifts from the substrate, the adhesion is less than perfect.

Rest in peace, Ken. Rated to 10 kN 2, lbf Can be paired with adapters to yield non-perpendicular peels Maintains constant peel angle throughout the test.

Is the plating on inside or outside of the pipe or both sides? These limitations are noted generally in the test descriptions and are summarized in Table 1 for certain metallic coatings.

If permitted, test panels shall be astm b571 the same material and have the same surface finish as the item to be aztm and shall be processed h571 the same preplating, electroplating, and postplating cycle with the parts they represent.

The choice for each situation must be determined. If a part requires baking or heat treating after plating, adhesion tests should be carried out after such posttreatment as well. For example, an article that is astm b571 be subsequently formed would suggest a draw astm b571 a bend test; an article that is to be soldered or otherwise exposed to heat would suggest a heat-quench test.
