Rubber Stamping is a permanent marking method for applications requiring MIL-STD-130 (Table II).

This standard provides criteria for the selection of the application process, as well as all other specific requirements that will be part of the deliverable item, such as marking protocol, content, font size, type, location, etc.


Simply stating in the product definition data that the marking be in accordance with MIL-STD-130 is not sufficient. The item identification marking requirements must be determined by the Design and/or Acquiring Activity in their contractual instruments, and tailored to meet the needs of their specific application.
