DIN EN ISO 17075-2 (accredited)

Our accredited laboratory performs testing in accordance with DIN EN ISO 17075-2 (Leather – Chemical tests – Determination of chromium(VI) content in leather – Part 2: Detection and quantitative determination of chromium(VI)) professionally and using a standardized procedure.

DIN EN ISO 17075-2 specifies a chemical test method for the quantitative determination of hexavalent chromium in leather. Chromium(VI) may form in leather-based materials as a result of tanning processes or oxidative transformations and is considered potentially harmful to health, as it can cause skin irritation and allergic reactions.

In the test procedure according to DIN EN ISO 17075-2, the leather samples are first prepared and homogenized under defined conditions. Chromium(VI) is then extracted from the sample material using an appropriate extraction solution. The released chromium(VI) ions are subsequently detected and quantitatively determined by ion chromatography. The standard defines clear requirements for sample preparation, extraction time, reagents, calibration, and measurement conditions to ensure reproducible and standard-compliant results.

In our laboratory test report, the results are stated in mg/kg (ppm), allowing an unambiguous evaluation of the chromium(VI) content in comparison with legal limits or product-specific requirements.

Testing in accordance with DIN EN ISO 17075-2 is of particular importance for the safety assessment of leather goods, especially products in direct contact with skin such as clothing, footwear, bags, or seat covers. It supports manufacturers, retailers, and certification bodies in verifying compliance with chemical limit values and ensuring a high level of material and product safety.
