NF EN ISO/CEI 17025 : General requirements regarding the expertise of test and calibration tests

NADCAP Accreditation: section MTL

Within the framework of its quality policy, EXOVA has opted for setting up a quality system which is described in this quality manual. It covers all the services provided.

• Machining of test specimens and toolilngs,
• Materials  mechanical characterisation testing (dynamic, static…),
• Micrographic examination of materials and electronic devices,
• Extensometer, oven and strain gauge calibration and checks,
• Supply of processs qualification test specimens,
• Setting up inter-lab proficiency test campaigns.

EXOVA was accredited by NADCAP  with mention mention « Merit program » for the folowing scope :
