Metaspec manufactures test specimens used in quality assurance testing by MIL-P-27418. This Military Specification covers electrodeposited soft nickel plating using a sulfamate bath. The production or quality control requirements generally require that the parts being plated be tested for conformance to MIL-P-27418. 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.
