Chromium VI after UV ageing

Item ID: 10200

Chromium VI after UV ageing

 Protect the health of your consumers by having your products tested for Chromium VI.

Let your products test and convince your customers with your high safety standard!

Content of the testing

What is content of the testing?

We determine the content of Chromium VI after the artificial ageing of your product samples through irradiation with artificial light for 24 hours. The exposure to light is carried out according to DIN EN ISO 105-B02 (exposure cycle A1, procedure 5). 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 UV ageing.

Are you also interested in having your product tested after thermal ageing? We also offer these tests for Chromium VI.


Which materials can be tested for Chromium VI ageing?
  • leather
  • in particular chrome-tanned leather and leather fiber materials, e.g. natural, bright lining leather in shoes and clothing
  • traditional leather
  • as well as leather straps and leather gloves


Which limits must be hold?

Legal limit value: Leather products that come in contact with skin, which contain more than 3 mg/kg (detection limit of the testing method) of Chromium VI, are banned in the EU.

What does ... mean?

Legal limit value

In order to protect the consumer, the use of certain chemical substances is regulated by law. Accordingly, legal limit values for the use of these substances are defined and regulated. These legal limits may not be exceeded.
This way you ensure that your products do not pose any health risks to your customers due to Chromium VI.

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.

Required sample details

  • Product category
    Your material to be tested will later be assigned to this product category.
  • Article name
    What is the article name of the product, in which the material to be tested will later be used?
  • Component
    The component to be tested
  • Material
    What material is the component to be tested made of?
  • Color
    What is the color of the material?
  • Composite sample
    As a general rule, composite samples are prepared to shorten the processing times. A composite sample consists of up to three individual materials in one sample, which are combined in equal parts and are subjected together to a specific chemical test. The number of samples mixed depends on the requirements.
  • Retests
    Preparing composite samples generally bears the risk that the result of the composite sample may show deviations, suggesting that at least one of the individual materials does not comply with the legal or standard market limits. To determine which of the materials within a composite sample had caused the deviation, all materials of the composite sample must be individually retested. This leads to additional costs which are the responsibility of the client.

    In which language should the test report be issued?
