ASTM B545 Special Test Specimens

Special test specimens (also called separate test specimens) used in quality conformance testing by ASTM B545 (Specification for Electrodeposited Coatings of Tin). These specimens are made from the same alloy as the parts being plated, and their size, shape, surface finish, and number are agreed on between the purchaser and the seller (or the end user and the plater). Some common sizes for separate test specimens include 1" x 4", 3" x 6", and 3" x 10".
