Tests & Qualifications

1) Ferric etching
Acid attack before F.P.l, to clean parts.

Our equipment : Ferric etch line.

2) F.P.I (Fluorescent Penetrant Inspection)
lnspection method used to detect cracks and discontinuities on parts after machining.

Our equipment : F.P.I line

3) C.M.M. units (Co-ordinate Measuring Machines)

A three dimensional measurement system to inspect parts with a complex geometry.

Our equipment : 4 C.M.M. in air-conditionning.

4) Profile Projector
To compare theoretical profile with achieved profile.

Our equipment : 2 Profile Projectors, ‘1000mm in diameter each.

5) Ultrasonic testing
With this method, we inspect the position of hole and control the wall thickness of the part.

Our equipment : One ultrasonic depth test instrument.

6) Airflow testing
We can measure air mass flow up to 0,66 lbm/sec using one of the three flow methodes : plenum pressure, pressure ratio or flow parameter,

Our equipment : One airflow system (C.C.D.I.).

7) Moment weighting
With this system, we can define the gravity center of the part.

Our equipment : One moment weight system (SCHENCK).

8) Frequency testing
We are able to measure the own frequency of vibration, to be sure of the resonance of the part.

Our equipment : One frequency test system.

If required, other special tests such as X-Ray, metallurgical tests, etc, can all be arranged externally with specialized and approved laboratories, with whom the company has long established co-operation agreements.
