In all areas, we fulfil the high quality demands of ISO 9001 and IATF 16949.
DEKRA Intertec Certification GmbH certifies that we use a quality management system according to ISO 9001:2015 and an environmental management system according to ISO 14001:2015.
The certification audit according to IATF 16949 was also successfully completed.
The UL test symbol is the most accepted and recognised seal of quality for the security of electrical and electronic products in North America. The UL certification of products or subcomponents such as marking systems (labels or type plates) is the prerequisite that is needed in to be able to sell products in the USA.
The Witte company group offers its customers access to the North American markets by means of various types of certification, which are explained in more detail in the following.
UL is also recognised by the Canadian standard control committee, and the C-UL test symbol is highly regarded in Canada. Nonetheless, the Witte company group also has CSA certification (CSA = Canadian Standards Association).
On the one hand, the listed materials (film/foil in this case) are listed in the individual categories, and on the other hand the certified substrates/surfaces, temperature ranges and application areas and the colour tapes for them. All of these requirements must be met for a label to be UL-compliant. The permitted film/foil is tested in accordance with UL 969, which applies to this product.

Repackaging of UL-accepted materials (Repackaged Product Program). Repackaging includes activities such as:
– Cutting big rolls into smaller ones
– Cutting up the material into smaller pieces
– Re-rolling the material into smaller rolls
– Cutting up the material into individual labels
Re-packed materials are supplied as blank labels. Printing takes place at the end customer’s.
The CSA Group (former Canadian Standards Association) is an independent standards organisation from Canada. The CSA test symbol indicates that products conform to the applicable standards prescribed by North American law.
The permitted film/foil is tested in accordance with the applicable standard for this product CSA Standard C22.2 No 0.15-15, adhesive labels.
Here too, film/foil, subsurfaces, temperature ranges, application areas and printing methods are defined exactly.
Complicated applications can be simulated and tested in our laboratory in order to specify suitable materials or carry out testing in according with required standards.
