Looking for standard rub test for platings

 

I am constantly being asked for an estimate of how long decorative plated metal finishes will last under normal indoor conditions for hardware, plumbing, or architectural metal items. Is there a standard wear test or rub test for plated finishes that simulate the wear on plated finishes over time for household use that might indicate this? This would also include a few of the clear organic coatings normally applied by manufacturers and building maintenance companies to their plated items.

Thanks,

No.

You will have to separate the problem into types of item, (screwhead, sheet, door bracket and handles, etc.) the kind of finish, (black oxide, nickel, zinc, chrome, copper, organic coating type, etc.) You will need to describe what 'normal' is. Describe where indoors (bathroom, kitchen, bedroom)

There is lots of experience with these coatings, but you will have to ask for each one, since some will have experience with one (like copper-nickel-chrome on plumbing brass), but not another (enamel on kitchen hardware).
