Inspecting tire chains

Since we are recovering from winter weather, it's a good time for me to take my chains off the rack and inspect them before putting them back up for next season to determine if any replacements are needed; long before I'm faced with a situation to use them, only to discover I have a problem before I can.

Problem is that my last 2 companies (over 8odd years) used sox (which I liked in concept, just not how they made it through the design stage), so I've forgotten what to look for.

Does anyone have a document that I can use?
