EN3019-050
Reusability test after baking:
In QTR, we have elongation = 0,0911 mm / 911 µm
Could you please fix unit conversion?
May we have the detailed math for elongation?
In PFC, for both basket and nut, there are passivation operations.
Have these passivations been done internally or externally?
Only for basket, we have a lubrication operation. Has this operation been done internally or externally?
If surface treatment operations were performed internally (since QTR is dated April 2019), this qualification should be now updated/amended because HFS St Cosme has to subcontract surface treatment operations now (fire accident in June 2019).
EN3020-050
These nuts are silver plated.
Baskets are passivated and lubricated (temporary I guess). Have these operation been done internally?
If these surface treatment operations were performed internally (since QTR is dated April 2019), this qualification should be now updated/amended because HFS St Cosme has to subcontract surface treatment operations now (fire accident in June 2019).
Many thanks.

Mr Gauther, please find below our replies to your comments :
1 – Conversion error , we must read 91.1µm
2 – surface treatment performed before the fire in Howmet St Cosme plant so before the 10/09/2019. We know that we must submit a ACP008 dossier in order to deliver the new parts. The MCR will be submitted to ASD/ CERT when the ACP003 will be approuved.
Hoping these replies help you to validate the qualification, thanks.
kind regards,
Nadege Richard
Many thanks for these answers.
