Certifications and quality system — stated precisely, scope by scope

What does Arrow Energy's ISO 9001:2015 certificate actually cover?

The TÜV Rheinland certificate covers spare parts, installation and maintenance services — the exact scope wording. It attests that those activities run under an audited quality management system: documented procedures, competence records, nonconformity control and corrective action, verified by third-party surveillance audit. It is not a product certificate and it does not certify design output.

We state that boundary deliberately, and we do not write "ISO-certified manufacturing", because ISO 9001 certifies a management system for the activities in its scope — nothing more. Assurance for fabrication comes from a different mechanism: construction codes. Boiler pressure parts — the scope described on the boiler pressure parts page — are fabricated to ASME Section I or JIS practice as the contract requires: code-listed materials, qualified weld procedures, calculated minimum wall thicknesses, and the hydrostatic test. Where a project requires an ASME code stamp and authorised-inspector involvement, that scope is stated per project in the quotation — which code edition, which stampholder, which witnessed inspections — rather than implied generally. CONFIRM: current code-stamp scope held, if any.

The practical consequence for a buyer: for spares, installation and maintenance — including the boiler spares scope — the ISO certificate applies directly. For new pressure-part fabrication, ask for the project quality plan; it names the code, the inspection regime and the documentation you will receive, and it is a firmer assurance than any logo.

Each fabrication project runs to an inspection and test plan agreed before work starts. The ITP lists every verification — material check, fit-up, weld visual, NDT, dimensional survey, trial assembly where specified, hydrostatic test for pressure parts, surface preparation and coating, pre-shipment inspection — and marks each as a review, witness or hold point for the customer or their third-party inspector. A hold point means fabrication stops until the point is signed; customers are welcome at the Samut Sakhon factory for any of them, and the same ITP logic extends to site work and commissioning.

At handover the project ships with its QA documentation set: the signed ITP, mill test certificates indexed by heat number and component, WPS/PQR/WPQ records, NDT reports, dimensional and hydrostatic test records, coating reports and the as-built drawing register. Years later, this dossier is what lets a plant order a replacement part in the correct material without guesswork — the working definition of quality documentation that was worth producing.
