Troubles with tonality differences  

++

My Questions are -
1. Our coated panels are having peak tonality difference.How to check (any meter)the color tonality difference ?
2. Our coated Aluminium panel shows whity patches isolated.
3.Is there any tests to the question 2.
4.Any Tolerance for Tonality Difference ?
5.Any relevant standards in ASTM for above ?

Thanks,
