ENCLOSURE 7
(NOISE TESTS)
The acoustic emission of this model is linked to the machine type, but also to the mechanical
characteristics and to the type of profile to be processed and to its length. In case of no precise
indications it has been decided to follow the recommendations given by
UNCSAAL
(Unione
Nazionale Costruttori Serramenti Alluminio Acciaio Leghe). The test method is therefore
referred to the
ISO - 3746
standard and to the use of the R40 profile of the firm Metra for a
cutting length of 2000 mm.
