FAIR: thread tolerance in this document is 4H6H whereas in EN2909, tolerance is 4H5H (from MJ6 to MJ10). The higher the number, the higher the tolerance is.
Could you please tell us which tolerance class shall be considered?
QTS: could you please add NDT?
Just a remark about FPI: sample size carried out is 50 parts instead of 200 (EN3004, discontinuities are ranked as major defect with AQL=0,065%. Related sampling for this AQL is 200 due to a down-arrow marked against sample size 50 by considering a manufacturing batch size from 281 to 500).
This batch was manufactured in 2015, before ASD-CERT’s communication about sampling as per ISO2859-1 or ANSI/ASQ Z1.4.
Many thanks in advance,
Best regards.
We have correctly thread the parts in accordance with MJ8x1 4H5H, the error has been corrected on the attached dimensional statement.
CND has been added to QTS
All is fine for me now,
Approved on my side.
Best regards.
