That's a bit of a wide open question. If you're trying to simply verify whether not the chrome plating exists, immerse the part in hydrochloric acid. If you see a color change from blue to yellow on the finish, you had chrome present. If you want to verify thickness, corrosion resistance or other physical properties, refer to ASTM B456 for evaluation of decorative chrome finishes. It is very comprehensive.
Good luck.
