1. EN3637-080:
   Hardness: could you please add hardness values in HRC? Actual values are in Vickers units.
   FPI: why do we have two different sample sizes? (50 and 125 parts)

   Many thanks in advance,
   Best regards.

2. Dear Julien,
   Please find below the feedback from LISI VDR for these opened conditions:
   EN3637-080:
   – Hardness values in HRC => Actual values are in Vickers units. => LISI VDR cannot modify the values on the certificate but here is the equivalence in HRC of the measured values: 401 to 407 HV give 41.7 to 42.3 HRC (EN3005 requirement is 32 to 44 HRC)
   – FPI: 2 different sample sizes (50 and 125 parts) ? => LISI VDR carried out post forging FPI testing on 50 parts for internal verification on this batch. This operation should not have appeared on the Certificate of Conformity. The requested FPI has been carried out on 125 parts.

   Thank you in advance to manage these conditions,
   S.Garcia – MB
