The HOPPE Guarantees
HOPPE’s Operational Guarantee
Still the Handle of excellence after 10 years of intense operational strain!
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, as long as the respective assembly and maintenance guidelines are fulfilled; please see: Guarantee or PDF-file).
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 and extend beyond the tests and requirements of DIN EN 1906 or RAL-GZ 607/9.
HOPPE realistically tests door and window handles in situation doors and windows
The new quality benchmark
With the 10-year guarantee on the mechanical operation, HOPPE extends way beyond the statutory 4 years of European regulations.
1. Tests on door handles
There are two durability grades for door handles in DIN EN 1906 necessitating durability tests with various test cycles:
2. Tests on window handles
RAL-GZ 607/9 prescribes 10,000 turn/tilt test cycles in durability tests for window handles. HOPPE, again, tests in an application-related way. In tests for the operational guarantee, HOPPE window handles undergo a 15,000 turn/tilt cycle test on the window itself. This is the equivalent to 4 x opening and closing plus 4 x tilting and closing per day over 10 years (1 turn/tilt cycle = 1 x opening and closing of the window plus 1 x tilting and closing of window). The window handles are then tested for their stability to ensure perfect operation.
