The Fischerscope ST200 from Paul N. Gardner is a progressive-load scratch tester designed to analyze the adhesion and cohesion strength of coatings according to ASTM C1624, ISO 20502 and DIN EN 1071-3. Typical fields of application include hard material coatings; automotive engine and drive train components; electroplated coatings; characterization of hard anodic coatings; materials used specifically in medical technology applications; electronic components, connectors and bond wires; and plasma-applied coating systems.
Features include constant-load, progressive-load and incremental-load measurement modes; optical microscopy, friction-force acoustic-emission analyzing methods; a motor-driven XY stage and Z axis; the ability to measure curved surfaces with motion feedback control; an automatic image scan of the whole scratch; diamond indenters of various geometries; optical filters for contrast improvement; integrated electronics; two microscope objectives; and easy creation of test reports.

In Mechanical Finishing, All That Glistens Is … Or Is It?
Surface finish types for commercially supplied stainless steel sheet are detailed in various standards. ASTM A480-12 and EN10088-2 are two; BS 1449-2 (1983) is still available, although no longer active. These standards are very similar in that they define eight grades of surface finish for stainless steel. Grade 7 is “buff polished,” while the highest polish—the so-called mirror polish—is designated Grade 8
