Content of the testing

What is content of the testing?

Prior to determining the chromium VI content, the samples are subjected to an aging process at 80°C and 5% controlled humidity for 24 hours in an unventilated drying chamber.

The testing method is in accordance with EN ISO 17075-1:2017, "Leather – Chemical determination of Chromium (VI) content in leather" – Part 1: colorimetric procedure;

EN ISO 17075-2:2017,  "Leather – Chemical determination of Chromium (VI) content in leather" – Part 2: chromatography and EN ISO 20344 Section 6.11, DIN EN 420 and the official test method as specified in BVL B 82.02-11.

There is a EU-wide ban of Chromium VI in leather articles. With the EU Regulation 301/2014, this ban was also adopted in Annex XVII of the EC Regulation 1907/2006 (REACH). This regulation applies to products placed on the EU market after May 1, 2015.

This ensures that your products do not pose any health risks to your customers due to Chromium VI after thermal ageing.

Test process

  1. Order at the online shop

    Configure your desired individual chemical test in the TÜV Rheinland business client online shop and send us your purchase order.

  2. Delivery of material sample

    Please note that you must send the number of test samples/material samples required for testing to TÜV Rheinland at your own cost. For the exact location, please refer to the accompanying note for the test sample.

    Please enclose the accompanying note for the test sample (attachment of your order confirmation) with your test sample shipment or, for large shipments, attach it on the outside of the outer packaging.  This allows us to quickly and easily match your sample with your order. Receipt and registration of the test sample happens at the respective laboratory site. The same applies for the weighing of the materials to be tested, which is based on the amount of the sample required for the test (material sample collection).

  3. Testing

    The chemical testing of the material samples is performed in our DIN EN ISO 17025 accredited laboratories according to legal and standard market requirements. The chemical testing inevitably destroys the samples, and they cannot be reused.

  4. Sending of test results

    Analysis of the measurement results and documentation of the results in a test report.
