Re: [MW:12610] DFT ACCEPTANCE AND REJECTION OF PAINTING.

Dear John,

As per SSPC PA2 the minimum required thickness is 80% and maximum 120% of the required DFT for a single spot measurement.

as in your case 60 micron should be the min and 90 micron should be the max, hence it is not acceptable.

regards,
madhan

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.
