Is YUSI ISO 9001 Certified? Quality Certifications & Compliance

Is YUSI certified to ISO 9001?

Yes. Our quality management system is certified to ISO 9001:2015, covering the full production cycle from raw material inspection to final packaging.

  • Documented material inspection for every production batch
  • Traceable manufacturing records
  • Consistent product specifications across orders

Do YUSI lean pipe products carry CE certification?

Yes. Our lean pipe system products carry CE certification for European market compliance, meeting applicable health, safety, and environmental protection requirements.

What is the surface resistance of YUSI ESD pipe?

Our ESD product line is engineered to the static dissipative range required by electronics manufacturing, aligned with ANSI/ESD S20.20:

  • ESD pipe surface resistance: 106 to 109 ohm
  • Tested per batch, resistance certificates provided with delivery
  • Compatible grounding components: ground wires, common point grounds, wrist strap connectors
  • Suitable for EPA (ESD Protected Area) workstation builds

What material test documentation comes with an order?

Available with every order:

  • Steel tube wall thickness certificate (tolerance ±0.05mm)
  • Coating thickness verification (PE / ABS / ESD coatings)
  • Weld strength test reports (automated TIG welding, 85-95% of base metal strength)
  • ESD surface resistance test results per batch

How do I request certificates for a supplier audit?

Certificate numbers, issuing bodies and validity dates are stated on every quotation and provided on request. Contact our quality team with your audit requirements and we will supply the relevant documentation.

What Our Certificates Actually Cover

Certificates are easy to display and easy to misread. Here is what each one means for a buyer, and what it does not mean.

ISO 9001: the process, not the product

ISO 9001 certifies that our quality management system is documented and audited. It tells you that incoming material, in-process checks and final inspection follow written procedures, and that non-conforming parts are segregated rather than shipped. It does not certify that a particular workbench will hold a particular load. For that, ask for the load calculation or the test report.

CE: which directive applies

CE marking is not a single certificate. It depends on the product and the directive that applies to it. For our range, the relevant declarations are provided per product family, and the declaration of conformity is issued with the shipment documents. If a buyer needs CE documentation for a specific configuration, tell us the configuration before the order, because the declaration has to match what is actually shipped.

ESD: the number matters, not the label

An ESD workbench is only useful if the surface resistivity is in the dissipative range, typically 10^6 to 10^9 ohm, and if the surface is bonded to ground through the frame. We test the coated surface and can supply the measured value. A bench described as "anti-static" without a number is a marketing claim; ask for the test method and the reading.

Documents we can supply with a shipment

  • Declaration of conformity for the product family
  • Material certificates for steel tube and plate on request
  • Surface resistivity test record for ESD-coated products
  • Inspection report with packing list reference

Certificate numbers and issuing bodies are provided with the quotation package, so that your quality department can verify them against the issuing registry rather than against a web page.
