TTR Institute srl is an independent and established company whose core business (laboratory testing with particular specialization in plastic and metallic materials) aims to cover the requests of a certainly very specialized but at the same time underserved market area nationally and internationally.
The international recognitions achieved for testing (ACCREDIA certificate no. 00627) guarantee, on the one hand, the high qualitative standard reached and, on the other, the total impartiality and independence of the company, which positions itself on the market as a third-party body for the execution of product verification tests in compliance with the main international standards.
TTR Institute is also accredited as a Type A inspection body in accordance with ISO 17020 in order to provide the customer with a service, similar to testing, with national and international validity (ACCREDIA certificate no. 00627).
In addition to testing activities, the company therefore offers on-site inspection and verification services to meet customer needs, thus providing a complete service for product certification checks, inspections, and third-party expert reports, also for disputes following malfunctions and damages caused by installed products.
The company's internal structure is configured in a flexible and highly versatile manner so as to be able to adapt to customer requests while respecting high quality standards and with rapid response times. This allows our customers to obtain immediate feedback both for the conformity of the tested products and for their development, enabling them to achieve their set objectives in optimal times.
The technical staff's expertise, the instruments used, and the know-how are constantly evolving to meet market demands: TTR's Mission is to support the customer in verifying product performance against current regulatory standards!

Personnel Certification (or competence certification) is an independent third-party recognition issued to attest that an individual possesses and meets specific requirements.
TTR Institute s.r.l., through its accredited Certification Schemes and the expertise of its examiners, verifies that certain professional figures possess and maintain over time the necessary competence, understood as the set of knowledge, skills, and abilities required for the assigned tasks.
The evaluation and examination process, which allows for the issuance of the certificate, generally consists of an initial certification, periodic surveillances for maintenance, and renewal of the professional's certificate.
Certification therefore represents the attestation of professional competencies by a third-party, independent body.
TTR Institute's certification schemes are designed and managed in accordance with specifications, regulations, technical standards, national and international regulations, and the requirements of the UNI CEI EN ISO/IEC 17024 standard, providing the requirements that define the competence profile subject to certification.
