1. In PFC, could you please replace “salt batch” by “salt bath”, “length” “by length”?
   In FAI:
   Thread major diameter “d max” shall be equal to D1 min – 0,025 as per EN4072, Table 1, note a.
   D1min = 10 – 0,038 = 9,962 mm
   d max = 9,962 – 0,025 = 9,937 mm instead of 10,000 mm written in FAI.
   Actual values measured for major diameter are in line with d max = 9,937 mm, but the right d max shall be implemented for further production batches.

   Many thanks in advance,
   Regards.
