Tubing manufacturer with an ISO 9001-certified quality system
That the tubing you receive today is identical to the one you receive a year from now is no accident: it is a system. Delmàs has its quality management system certified to ISO 9001, so that every batch is manufactured, controlled and documented under the same audited procedure.

What ISO 9001 is
ISO 9001 is the reference international standard for quality management systems (QMS). It does not certify a specific product; rather, the organisation manages its processes —design, manufacture, control, continual improvement— systematically, documented and audited by an independent external body. It is the most widespread quality standard in the industrial world.
What it attests
An ISO 9001 certification attests that the company:
- Has its processesdefined and documented, with clear responsibilities and controls.
- Works oriented to customer requirements and to continual improvement.
- Manages traceability, non-conformities and corrective actions systematically.
- Undergoes periodic external audits that keep the certification alive.
What it means for you
For an industrial buyer, a manufacturer with ISO 9001 means predictability: that batch 1 and batch 100,000 are made under the same system, that incidents are handled by a procedure and that there is traceability behind every delivery. It reduces your supplier risk and simplifies your own quality audit.
The important nuance: it certifies the company, not the tubing
ISO 9001 certifies Delmàs's management system, not each tubing. The tubing meets its product standards (EN 10305, ASTM A513, JIS…) and is delivered with its EN 10204 certificate; ISO 9001 guarantees that the system it is made under is audited. That is why we never say "ISO 9001 tubing", but "manufacturer with an ISO 9001 quality system". Maintaining this distinction is technical rigour, not a detail.
When it is valued · sectors
An ISO 9001 system is valued across all industrial procurement and is often a requirement in tenders and in supplier approval. It is the basis on which more specific sector requirements are built, such as IATF 16949 in automotive.

Relationship with the product standards
ISO 9001 is the system umbrella; within it, the tubing is made to its product standards and delivered with its batch certificate.
