ASTM B545 Test Specimens

Metaspec manufactures test specimens used in quality testing by ASTM B545, which covers electrodeposited coatings of tin on metal. The production or quality control requirements generally require that the tin-plated parts be tested for conformance to ASTM B545. However, some parts (due to shape or size) can't be tested. In those cases, the specification allows 'special specimens' that are plated together with the other parts and then tested at the end of the plating process for conformance.

The following tests in ASTM B545 require test specimens. Click on the test method number for more information about specimens required for each test.
