  1. Hardness test: actual values are given in HV units. Could you please give us the conversion into HRC units?
    Silver plating: do we have a chance to know actual silver thicknesses?
    Many thanks in advance,
    Best regards,

  2. LISI’s answers from Nicolas ARLABOSSE:
    “The value measured on the part is specified on the certificate of conformity on the first page. The thickness is 6 µm for the 935133 batch number.”
    “The reference chosen for the renewal file is a Turbomeca standard ST98365 which is similar to EN3613-050016. However, the hardness requirement for the Turbomeca standard is specified on the drawing: 349 to 474 HV30. We do not have any manufacturing made directly on the EN3613-050 standard.”
    All is fine for me.
    Approved from my side.
    Best regards.
