Italian Certifications and Approvals

Test, certify or register your pipes and mechanical plumbing devices to Italian regulations and programs, including Origine Qualità Controllata (OQC).

NSF offers testing, certification and registration services for Italian water product regulations and programs, including NSF’s own OQC product registration. Registration to OQC distinguishes quality products made in Italy through continuous verification and regular inspection.

As the third-party administrator of OQC, NSF International verifies that all products comply with OQC guidelines. In addition to performing annual audits of your manufacturing facilities, we review quality, material safety and performance documentation.

We require validated third-party test reports to demonstrate your compliance with NSF/ANSI/CAN 61 or other international certifications. We also require proof that your products are made in Italy.

The OQC product registration program includes the following product categories:

Mechanical devices used in drinking water treatment, transmission or distribution
Pipes and related products
Mechanical plumbing devices

Products that comply with these requirements bear the OQC registration mark. Recognized around the world, the OQC mark is a unique quality label for Italian markets and export markets on a global scale.
