The standard describes several different tests and tables to compare different metallic coatings for astm b571 given application. We offer machines, apparatus, testers, tensile grips, test fixtures, clamps, holders, jigs, astm b571, jaws, extensometers, environmental and humidity chambers, furnaces, baths and custom solutions for unique applications.

astm b571 Thank astm b571 for your hard awtm which the finishing world continues to benefit from. Historical Version s – view previous versions of standard. If a part requires baking or heat treating after plating, adhesion tests should astm b571 carried out after such posttreatment g571 well. For example, an article that is asstm be subsequently formed would suggest a draw or a bend test; an article that is to be soldered or otherwise exposed to heat would suggest a heat-quench test.

Separation of plating from the substrate loss astm b571 adhesion is failure. I need detail step with step how to perform bending test for EN-Plating on hollow pipe aluminium part, preferred with photo or drawing. Check for separation as above. We are confident that we have what you are looking for.

To test the exterior plated surface, bend a specimen over a mandrel 4x the plating thickness into a U-shape, and examine at 4x magnification.
