English to Russian Tech/Engineering Aerospace / Aviation / Space Small, lightweight, and low-profile MiniSeal high crimp splices (mil-s-81824)

Добрый день!
Помогите, пожалуйста, перевести "certified" в следующем контексте:

Test reports:
The supplier shall furnish the activity responsible for qualification with a certified test report, in duplicate, showing quantitative results for class 1 or 2 splices as required by this specification and further certified in the forwarding letter by an officer of the supplier.

Заранее спасибо!
