Certifications and qualifications: standards, controls, and qualified processes for reliable operations
Certifications and qualifications are a key element in ensuring reliability, traceability, and control in industrial processes. At T.T.N. S.p.A., each process is managed according to recognized standards and validated through control systems that ensure consistency between technical specifications and the results obtained.
Compliance with international standards is supported by customer and industry qualifications, confirming the company’s ability to operate in complex, regulated production contexts. This makes it possible to manage technically demanding applications through a structured approach based on verified processes and measurable results.
Management system and international certifications
ISO 9001: quality and process control
ISO 9001 certification confirms the adoption of a quality management system focused on process control and continuous improvement.
The system makes it possible to:
- define and monitor production processes
- ensure process traceability
- maintain consistency between technical specifications and the finished component
UNI EN 9100: standard for the aerospace sector
UNI EN 9100 certification is specific to the aeronautics and aerospace sector, where precision, safety, and reliability are essential requirements.
It confirms the ability to:
- operate according to high quality standards
- manage complex, controlled processes
- ensure compliance with industry regulations
NADCAP: qualification of special processes
NADCAP certification concerns the validation of special processes, such as heat treatment and coating, which cannot be verified solely on the finished product.
It ensures:
- rigorous control of process parameters
- validation of machining processes and treatments
- compliance with international aerospace standards
ISO 14001: environmental management
ISO 14001:2015 certification confirms the adoption of an environmental management system designed to monitor and reduce the environmental impacts associated with production activities.
It makes it possible to operate with:
- resource control
- reduced environmental impacts
- continuous improvement of efficiency
ISO 45001: occupational health and safety
ISO 45001 certification confirms the adoption of a management system focused on protecting worker health and safety, with processes aimed at risk prevention and the continuous improvement of operating conditions.
SA8000: social responsibility
