Deposit ENP thickness can be measured by using sample coupons along with the parts, by means of weigh plate weigh method as per ASTM B733,para 9.3.5
If necessary, a microscopic examination of the cross section of the coupons can be carried out as per ASTM B733 para
9.3.1
If thickness is in the range of 25- 75 microns, i would suggest you to go for microscopic examination that shall be:-
Direct measurement by micrometer on coupons before and after the plating.
Acceptance: parts shall be considered non-conforming if one
measurement fails to meet the specified tolerance.

You can go for wet chemical method like weight loss method for better results.
