PFAS Testing for Powder Coatings: Our SGS Report Explained

Why we are sharing the report

A coating specification becomes more useful when buyers can review the evidence behind it. We commissioned SGS to test a sample of a powder coating material we use and are making the complete report available for customers who need material documentation for their sourcing review.

This article explains what was submitted, what SGS measured and how to read the results. The test was completed in October 2024; publishing the report here in November 2026 does not represent a new test.

What material did SGS test?

The report identifies the sample as INT600 POWDER, specification JN31J0. The tested part is described as black powder, sample A1, with SGS sample ID TAO24-0081249-0001.C001. SGS received it on October 21, 2024 and carried out testing from October 21 to 24, 2024.

The manufacturer is listed as AKZONOBEL. As the report explains, the sample and this identifying information were provided by the client. The test object was the submitted powder material, rather than a finished coated bracket or a complete hardware assembly.

What does the 470-PFAS scope cover?

PFAS stands for perfluoroalkyl and polyfluoroalkyl substances in this report. SGS describes the requested analysis as a 470-PFAS content test. Its scope includes named substances and the salts and derivatives identified in the report’s accompanying tables.

Testing used modified EN 17681-1:2022 and EN 17681-2:2022 methods, with LC-MS or LC-MS/MS and GC-MS analysis. The results are presented in mg/kg. The report also lists grouped and summed results, so the scope should be read together with the result tables and the explanatory notes. It is a defined targeted analysis, rather than a measurement of every possible PFAS or of total fluorine.

What do the ND results mean?

All reported results in the test tables are ND. SGS defines ND as Not Detected, below the method detection limit (MDL). In practical terms, the analysis did not detect the reported substances or groups at their applicable detection limits in this sample.

The individual numerical MDLs range from 0.010 to 0.500 mg/kg, depending on the test item. For example, the PFOS and PFOA entries on page 2 are each reported as ND with an MDL of 0.010 mg/kg. Other entries have different limits, and some summed rows do not list a numerical MDL. The full PDF preserves those distinctions.

ND is a meaningful analytical result, but it is not a statement of an absolute zero concentration. The cover directs readers to “See Results”; it does not issue a blanket PASS or a PFAS-free product certification.

How buyers can use this documentation

The report gives buyers a named material, an independent laboratory record, a defined test scope and reported detection limits. Those details make it possible to compare the evidence with the material specification required for a particular project.

For a specific SUPCONN product or an OEM order, the next step is to connect the product’s actual powder specification and production records with the tested material. A single powder sample report does not establish the result for every formulation, finished product or later production batch.

• Match the requested product, powder specification and production batch to the available material records.
• Read the named substances, salts and derivatives in the report against the customer’s required test scope.
• Check the applicable detection limits and whether the test date meets the project’s documentation requirements.
• Identify any additional finished-product or batch testing needed for the intended specification.

Clear evidence for a specific material

Our approach is to make the underlying document available and describe its findings accurately: the submitted INT600 / JN31J0 powder sample was tested by SGS, and all reported PFAS results were ND within the stated scope and detection limits.

If you need coating documentation for a particular item, contact us with the product code, required finish and test specification. That gives us a clear starting point for reviewing the relevant material records and any additional evidence your project requires.
