The roses have been subjected to axial strength tests,
based on the data provided by the UNI EN 1906: 2012 standard.
The tests have been carried out on roses at room temperature
and on roses kept at a temperature between -18°C and -12°C
for a period of 3 days.
the tensile strength has exceeded a force of 1.000 N,
grade 4 of the standard,
without causing deformations or damages to the rose and mechanism.
(the tests have been carried out internally in atp,
and the result is purely indicative and not binding).
