Content of the testingWhat is the content of the testing?
The detection of allergenic disperse dyes and additional dyes is being performed according to DIN 54231, which is identical to BVL B 82.02-10.
This ensures that your products do not pose any health risks to your customers due to Allergenic disperse dyes and carcinogenic dyes.
We also offer you the opportunity to have shoes and textiles tested for carcinogenic disperse dyes. Learn more here!
Testing based on composite samplesTesting for allergenic disperse dyes can be done via composite samples.
As a general rule, composite samples are prepared to shorten the processing times or to reduce costs for testing. A composite sample usually consists of up to three compatible individual materials in one sample, which are combined in equal parts and are together subjected to a specific chemical test. The number of materials mixed depends on the methodological requirements. Preparing composite samples generally bears the risk that the result of the composite sample shows deviations, suggesting that at least one of the individual materials does not comply with the legal or standard market limits. Which material within a composite sample caused the deviation is confirmed by retesting all individual materials of the composite sample. This leads to additional costs which are the responsibility of the client. This way you ensure that your products do not pose any health risks to your customers. By having your products tested, you convey your high quality standards to your customers!

- coated textiles
LimitsWhich limits must be hold?
Standard market limit: higher thanstarting at 1 mg/l (=15 mg/kg)
According to convention, a dye is considered "detected" if a content of > 5 mg/l was determined in the extract, which corresponds to a limit value of 75 mg/kg when weighing in 0.5g / extraction volume 7.5 ml.
What does ... mean?Standard market limit value
The use of certain chemicals is not regulated by law or only inadequately regulated from the perspective of market players or consumer protection organizations. Therefore, the market itself established commonly accepted limit values, which are adhered to by manufacturers of materials and by trading companies. Frequently, these standard market limits impose stricter requirements on the use of these chemicals than already existing legal limit values.

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.
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).
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.

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.
