[MW:12607] DFT ACCEPTANCE AND REJECTION OF PAINTING.

Dear All,

Can anybody give the acceptance and rejection criteria as per SSPC PA2.  I have applied primer to the shell surface of storage tank.  The minimum DFT required is 75 micron.  The actual average DFT is  70 micron and above but at some spot I got 15, 30 , 40 microns. Is it acceptable the total area is  2500 M2.

I have taken 5 spot reading in 100 Sqft and each spot is the average of three single reading, in the single reading i am getting 15, 30, 40 microns but average spot reading is above 70 microns. 

Thanks in advance 
Manoj John.
