With our emblem »Quality for the future« we guarantee that KLUG products fulfil the requirements to meet maximum archival permanency (ageing resistant). Each of our products has a »Quality Guarantee Certificate«, which legally covers far more than the normal warranty terms, ensuring that the material used meets the requirements for guaranteed permanency.
For you as our valued customer that implies, regardless of any individual tests and results, such as those from independent institutes, for example "The Paper Technological Foundation (PTS)", the quality of the product supplied meets the guaranteed requirements stated in the guarantee certificate. If the quality of the product delivered is contrary to your expectation, then you may with this binding certificate claim for damage, for replacement or for return without any obligation.
We request you to contact the Quality Assurance dept. at email@example.com oder directly by telephone at +49 (0)8323 9653 366.
This applies even if the delivered product does not officially have a "Quality Guarantee Certificate" provided. Generally a quality guarantee covers the entire product and not just an individual lot. Apart from a batch test or just certain materials of the product being tested, which is sometimes required in tenders, these tests will always offer you a glimpse into the past. The tests in general do not cover the audition of the complete product. The "Quality Guarantee Certficate" provides our customers and endusers of KLUG products an indefinite guarantee far beyond the legally required minimium of 24 months.
