This Aerospace Material Specification covers the requirements for electrodeposited zinc-nickel alloy plating. Production or quality control requirements generally require that the parts being plated be tested for conformance to AMS2417. However, some parts (due to shape or size) can't be tested. In those cases, the specification describes 'separate specimens' that are plated together with the other parts and then tested at the end of the plating process for conformance.
The following is a list of tests in Specification SAE AMS2417 that use separate test specimens. Click on the test method number for more information about specimens required for each test.
SAE AMS2417 §4.3.3 Separate Test Specimens SAE AMS2417 §3.4.2 Thickness SAE AMS2417 §3.4.3 Adhesion SAE AMS2417 §3.4.4 Corrosion Resistance
SAE AMS2417 §3.4.5 Hydrogen Embrittlement (see ASTM F591)
