A. Hello Henry!

To get a copy of any US military or federal specification, such as QQ-N-290, go to: ~~astimage.daps.dla.mil/quicksearch/~~ and type the appropriate number in the document ID box.

Good luck!

Ed. note 5/23/13: Make that quicksearch.dla.mil/ currently

A. QQ-N-290 is the US Federal Specification for electrodeposited nickel. Class 1 is for corrosion protection but you will need to read the entire specification to understand the requirements.
