Report Acceptance and Global Regulatory Compliance

All measurements performed within our melamine foam testing service are executed under the fully accredited scope of our ISO/IEC 17025 quality management system. Each test report that carries the ILAC mark is therefore automatically recognised by regulatory authorities, notified bodies, customs offices and supply‑chain partners in all major economies. For melamine‑foam manufacturers, acoustic‑panel converters, insulation‑product suppliers and cleaning‑sponge importers anywhere in the world, the report constitutes legally robust, internationally accepted evidence that the density, the mechanical strength, the thermal conductivity, the fire‑reaction class, the sound‑absorption coefficient and the long‑term durability of the melamine foam have been determined in accordance with the applicable ISO, ASTM, EN and customer‑specified methods. The documentation can be directly used to support CE marking under the Construction Products Regulation, the issue of inspection certificates according to EN 10204 or equivalent national standards, the compilation of the technical file for the type‑examination, and the resolution of commercial and technical disputes concerning the quality and the performance of any melamine‑resin foam product.
