HOPPE’s operational guarantee

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".

 

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.

 

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.

 

HOPPE realistically tests door and window handles in situ, – on 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.

 

Grade 6:
Medium frequency of use, for residential hardware: 100,000 test cycles (1 test cycle = once opening and closing of a door).
 

Grade 7:
High frequency of use, for non-residential hardware: 200,000 test cycles.

 

Application-related standards are set for the HOPPE guarantee on the mechanical operation. In all durability tests, the door handles are tested on the doors themselves. Residential hardware is tested in 182,500 operational cycles (1 cycle = 1 x opening and closing the door) and handles for non-residential use are tested in 255,500 operational cycles. This is the equivalent of 50 or 70 operational cycles a day over a period of 10 years. Neither the door 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.

 

 

 

 

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.
