HOPPE’s Operational Guarantee

HOPPE’s Operational Guarantee

10-year guarantee on the mechanical operation

According to HOPPE, a brand-name product keeps its promise of quality to the enduser. As a way of ensuring this, HOPPE gives a 10-year guarantee on the mechanical operation of all door and window handles; please see “Guarantee”.

HOPPE realistically tests door and window handles in situation doors and windows.

Realistic load testing

HOPPE brand name products undergo numerous tests to ensure flawless operation. Static impact tests and durability tests are also made depending on the product type. These closely reflect the everyday knocks hardware has to take.

Whereas for DIN EN 1906 and RAL-GZ 607/9 hardware is tested in isolation, HOPPE, more realistically, also conducts operational tests when fitted on the door and window itself. This means that we test not just the function, but also the durability of the attachment between hardware and door or window. The number of operation cycles here is far higher than those demanded by the standards mentioned above – but after all we are talking about the HOPPE Handle of excellence here.

Neither the door or window handle itself, nor any part of it, must become loose during the course of the test. The sets are then tested for their stability, ensuring they work flawlessly.

Still the Handle of excellence after 10 years of intense operational strain.
