There is a mistake in EN3712:2007:
In EN3712:2007, rivet hole dimension “S” has a tolerance equal to 0/+2,2 mm.
Fortunately, HFS considered actual tolerance: 0/+0,2 mm.
Thus, this is not a blocking point, many thanks to HFS for correcting this.
This should be addressed to ASD-STAN for correction.
QTR, dimensional test report:
“J” dimension is considered as minimum value whereas EN3712 specifies this dimension as a maximum.
Hopefully, actual values are in line with 8,7 mm maximum.
Could you please fix this?
Many thanks in advance
Best regards, Julien
Dear Mr Gauther,
It’s a typo on J dimension, it was updated in the QTR 7580 revision A (see it attached on Additonal Documents)
