Control is ours.
The laboratory is inside the plant. Coating thickness and alloy are measured lot by lot, not on request — and certified inspection enters the scope when your project requires it.
The fear behind every supplier audit is simple to state and expensive to live with: am I going to have to stand over this one? Our answer is not a promise, it is where the equipment sits. Measurement is a step in the process here, not a service we go out and buy when someone asks for evidence.
What we measure, and why each one is there.
Coating thickness and alloy — X-ray fluorescence
Two spectrometers, a Skyray Thick200 and a Thick800A. Two matters more than it sounds: process measurement does not stop while one is away for calibration. Standards are traceable to an ISO/IEC 17025 accredited laboratory — the standards are accredited; we are not an accredited laboratory, and we keep that distinction because a supplier who blurs it is telling you how they will describe the rest of the job.
Salt spray — ASTM B117 and NBR 8094
Our own chamber, calibrated, for whatever duration the specification asks for. Some of the figures published on this site come from an external laboratory or from the technology licensor, and each one says so on its own line — naming the source is what makes a number usable.
Bath analysis
The bath is where the alloy is decided, and it drifts. Analysing it is how the deposit stays inside the 12 to 16% nickel range across a production run, rather than only in the sample that happened to be checked.
Certified inspection, on top of it.
Where the project specification requires certified inspection, it enters the scope: ABRACO and NACE/AMPP, levels 1 and 2, through certified partners. ABRACO is the Brazilian corrosion authority — in this market it is the qualification clients actually ask for, and its certification is held by a person, not a company: issued by the SNQC-CP under procedure ABRACO 001, with industrial painting inspection following ABNT NBR 15218:2022.
Two things this is, and one it is not. It is inspection to IOGP S-715 §10.2.5, which asks for a certified inspector. It is available when your specification calls for it, rather than as a standing cost on every order. It is not an applicator-company qualification — FROSIO, NACE NIICAP AS-1S or SSPC QP-3 are a different clause of the same standard, and we do not present one as the other.
What we hold, and what each one covers.
A qualification is granted for a process and a plant, not for a company in general — so the scope travels with the name every time.
| Body | Type | Scope |
|---|---|---|
| BSI | Certification | ISO 9001:2015 quality management system · certificate FS 517766 |
| TechnipFMC | Qualification | Cadmium — about ten years on the approved supplier list |
| IBQN | Qualification | Supply to the nuclear chain |
| PPG (Whitford) | Qualification | Xylan® application — the line is only supplied to an applicator qualified by the coating manufacturer |
The Petrobras specifications converge on the same base standards we work to: ASTM B766 · ASTM B841 · ASTM B633 · Fluoropolímero. Heat treatment follows ASTM B849 and ASTM B850, to the standard and class the specification determines.
Named here, sent on request.
Test reports and calibration certificates are named on this site with the standard, the class and the result — enough to check whether the document answers your question before you ask for it — and are sent on request to clients with an active project. The ISO 9001:2015 certificate is published openly.

What buyers ask before the order.
Will I have to supervise this supplier?
That is the question the whole page answers, so here it is first: no. Control is ours. We run our own laboratory inside the plant under ISO 9001:2015 — coating thickness and alloy by X-ray fluorescence, salt spray, bath analysis — and the measurement happens lot by lot, not on request. When your specification requires certified third-party inspection, that is added to the scope on top of it.
Is your laboratory ISO/IEC 17025 accredited?
Our measurement standards are traceable to an ISO/IEC 17025 accredited laboratory, and calibration certificates carry that traceability. The distinction matters and we keep it: using accredited standards is not the same as being an accredited laboratory, and a supplier who blurs the two is telling you something about how they will describe the rest of the job.
Who inspects, and to what qualification?
Our own control comes first, under ISO 9001:2015. Where the project specification calls for certified inspection, it enters the scope through certified partners at ABRACO and NACE/AMPP levels 1 and 2. ABRACO is the Brazilian corrosion authority and its certification is held by a person, not a company — issued by the SNQC-CP under procedure ABRACO 001, with painting inspection following ABNT NBR 15218:2022. Note what this is and is not: qualified inspectors are not the same thing as an applicator-company qualification such as FROSIO, NACE NIICAP or SSPC QP-3, and we do not present one as the other.
How long can you run salt spray?
Our chamber is our own and calibrated, in ASTM B117 and NBR 8094, and the duration is whatever the specification asks for. Some published figures come from an external laboratory or from the technology licensor — and each one states which, on its own line of the table. That is the point of naming the source: a figure you cannot trace is a figure you cannot use.
Can I get the test report?
Test reports and calibration certificates are named on this site with standard, class and result, and sent on request to clients with an active project. The ISO 9001:2015 certificate is the one document published openly: BSI, number FS 517766.
Why measure alloy and not just thickness?
Because thickness alone does not tell you whether the coating will do its job. A zinc-nickel deposit outside the 12 to 16% nickel range looks identical to one inside it — same colour, same gloss, same thickness reading — and corrodes differently. The failure mode is invisible on the part, which is exactly why it has to be measured rather than assumed.
