Dear Customers,

As a result of urgent rebuilding measures, we will be able to continue our business operations only to a very limited extent from November 29, 2017 until probably January 2018.

We strive to handle very urgent orders, but can not guarantee that. We will inform you as soon as normal business operations are possible without restriction.

We ask for your understanding and apologize for the inconvenience.

Standardized production of auxiliary products for colour fastness tests according to ISO 105 series

Due to high demand DEK had to synthesize new quantities of some of our colour fastness auxiliary materials.

Now we have good stocks of the Blue Wool References
1 – 8
and of the Grey Scale for Carpets.

All the newly synthesized products have been tested by accredited institutions and meet the requirements of ISO 105 and DIN EN ISO 105 series standards. All the materials for the testing of colour fastness of textiles from our stock are supplied with appropriate certification.

For standardized testing of colour fastness according to ISO 105 and DIN EN ISO 105 series the use of auxiliary products supplied by DEK can be guaranteed that objective testing of coloured textiles will stand up to any comparison.

March 2011

The availability of Blue Wool Reference No. 1-8 is guaranteed for the future!
