Mecasem is your essential quality service provider. We carry out mechanical tests, fatigue tests, durability tests, metallographic examinations and chemical analyses, climatic tests, ageing tests, heat treatments and non-destructive tests. We have NadCap accreditation for mechanical testing, fatigue testing and machining services. We also machine our own test specimens for a complete turnkey service. Whatever your field of activity – aeronautics, defence, transport, construction and civil engineering (Infrastructure & Housing), Energy, pharmaceutical and medical, food processing ou industrial supplies– Mecasem offers industrial tests (mechanical tests, fatigue tests, durability tests) to meet your specific needs.
MACHINING
Mecasem has specialised in preparing test specimens since 1980.
This expertise is recognised by demanding customers in the leading sectors of activity in aeronautics, nuclear, metallurgy, medical, etc.
QUALITY AND APPROVALS
The quality level is guaranteed by our ISO 9001, ISO 9100, Nadcap and Cofrac EN 17025* approvals and certifications. Our machining operators are trained and qualified in the latest technological developments. Guaranteed traceability.
SHORT LEAD TIMES
Our machining workshops integrated within our laboratories and our inventory of machines equipped with all the appropriate machining resources provide maximum flexibility and very responsive machining lead times. Our independent testing laboratories have established partnerships with the main inspection bodies: BV, SGS, TUV, Lloyds’ Register, etc.

TESTS ON YOUR PARTS UNDER PRESSURE AND AT TEMPERATURE
Our experts are familiar with the latest standards and regulations, audited annually by an independent certified body. Our technical team adapts to any specific procedure.
We help you define your own test protocol. We have a wide range of test facilities and services, video data recording, monitoring of physical characteristics (pressure, temperature, flow rate, etc.), electronic signature of test reports and data transmission.
Leak detection – Burst tests:
– Hydraulic pressure tests (100 bar)
– Pneumatic pressure tests (33 bar)
– Helium leak detection, specify range 1.10-8 mbar.L/s
– Hydrogen leak detection, specify range 1.10-6 mbar.L/s
